| Version: 1.9.15p5 | Vendor: openSUSE |
| Release: 2.2 | Build date: Mon Jul 29 06:55:32 2024 |
| Group: System/Base | Build host: reproducible |
| Size: 8161740 | Source RPM: sudo-1.9.15p5-2.2.src.rpm |

| Summary: Execute some commands as root | |
Sudo is a command that allows users to execute some commands as root. Sudo reads either /etc/sudoers or /usr/etc/sudoers (in that order, whichever one it finds first), to determine what users have access to sudo and which commands they can run. Sudo logs all its activities to syslogd, so the system administrator can keep an eye on things. Sudo asks for the password to initialize a check period of a given time N (where N is defined at installation and is set to 5 minutes by default). Administrators can edit the sudoers file with 'visudo'.

* Mon Jul 29 2024 Simon Lees <[email protected]>
- A quick note that bsc#1227574 is expected behavior in this
version of sudo. It was a regression in 15.6 which doesn't have
the /etc/ split for pam.d yet.
* Tue Jan 02 2024 Otto Hollmann <[email protected]>
- Update to 1.9.15p5:
* Fixed evaluation of the lecture, listpw, verifypw, and fdexec sudoers
Defaults settings when used without an explicit value. Previously, if
specified without a value they were evaluated as boolean false, even when
the negation operator ('!') was not present.
* Fixed a bug introduced in sudo 1.9.14 that prevented LDAP netgroup queries
using the NETGROUP_BASE setting from being performed.
* Sudo will now transparently rename a user's lecture file from the older
name-based path to the newer user-ID-based path. GitHub issue #342.
* Fixed a bug introduced in sudo 1.9.15 that could cause a memory allocation
failure if sysconf(_SC_LOGIN_NAME_MAX) fails. Bug #1066.
* Mon Dec 18 2023 Otto Hollmann <[email protected]>
- For existing products (SLE15-SP* and older) keep using /etc and don't
switch to /usr/etc. So only SLES16/ALP, Tumbleweed and newer products
will use both /etc and /usr/etc locations.
* Mon Dec 18 2023 Otto Hollmann <[email protected]>
- Update to 1.9.15p4:
* Fixed a bug introduced in sudo 1.9.15 that could prevent a user’s
privileges from being listed by sudo -l if the sudoers entry
in /etc/nsswitch.conf contains [SUCCESS=return]. This did not affect the
ability to run commands via sudo. Bug #1063.
- Update to 1.9.15p3:
* Always disable core dumps when sudo sends itself a fatal signal. Fixes a
problem where sudo could potentially dump core dump when it re-sends the
fatal signal to itself. This is only an issue if the command * received
a signal that would normally result in a core dump but the command did
not actually dump core.
* Fixed a bug matching a command with a relative path name when the sudoers
rule uses shell globbing rules for the path name. Bug #1062.
* Permit visudo to be run even if the local host name is not set. GitHub
issue #332.
* Fixed an editing error introduced in sudo 1.9.15 that could prevent
sudoreplay from replaying sessions correctly. GitHub issue #334.
* Fixed a bug introduced in sudo 1.9.15 where sudo -l > /dev/null could hang
on Linux systems. GitHub issue #335.
* Fixed a bug introduced in sudo 1.9.15 where Solaris privileges specified
in sudoers were not applied to the command being run.
* Wed Nov 22 2023 Otto Hollmann <[email protected]>
- Update to 1.9.15p2:
* Fixed a bug on BSD systems where sudo would not restore the
terminal settings on exit if the terminal had parity enabled.
GitHub issue #326.
- Update to 1.9.15p1:
* Fixed a bug introduced in sudo 1.9.15 that prevented LDAP-based
sudoers from being able to read the ldap.conf file.
GitHub issue #325.
- Update to 1.9.15:
* Fixed an undefined symbol problem on older versions of macOS
when "intercept" or "log_subcmds" are enabled in sudoers.
GitHub issue #276.
* Fixed "make check" failure related to getpwent(3) wrapping
on NetBSD.
* Fixed the warning message for "sudo -l command" when the command
is not permitted. There was a missing space between "list" and
the actual command due to changes in sudo 1.9.14.
* Fixed a bug where output could go to the wrong terminal if
"use_pty" is enabled (the default) and the standard input, output
or error is redirected to a different terminal. Bug #1056.
* The visudo utility will no longer create an empty file when the
specified sudoers file does not exist and the user exits the
editor without making any changes. GitHub issue #294.
* The AIX and Solaris sudo packages on www.sudo.ws now support
"log_subcmds" and "intercept" with both 32-bit and 64-bit
binaries. Previously, they only worked when running binaries
with the same word size as the sudo binary. GitHub issue #289.
* The sudoers source is now logged in the JSON event log. This
makes it possible to tell which rule resulted in a match.
* Running "sudo -ll command" now produces verbose output that
includes matching rule as well as the path to the sudoers file
the matching rule came from. For LDAP sudoers, the name of the
matching sudoRole is printed instead.
* The embedded copy of zlib has been updated to version 1.3.
* The sudoers plugin has been modified to make it more resilient
to ROWHAMMER attacks on authentication and policy matching.
This addresses CVE-2023-42465.
* The sudoers plugin now constructs the user time stamp file path
name using the user-ID instead of the user name. This avoids a
potential problem with user names that contain a path separator
('/') being interpreted as part of the path name. A similar
issue in sudo-rs has been assigned CVE-2023-42456.
* A path separator ('/') in a user, group or host name is now
replaced with an underbar character ('_') when expanding escapes
in @include and @includedir directives as well as the "iolog_file"
and "iolog_dir" sudoers Default settings.
* The "intercept_verify" sudoers option is now only applied when
the "intercept" option is set in sudoers. Previously, it was
also applied when "log_subcmds" was enabled. Sudo 1.9.14
contained an incorrect fix for this. Bug #1058.
* Changes to terminal settings are now performed atomically, where
possible. If the command is being run in a pseudo-terminal and
the user's terminal is already in raw mode, sudo will not change
the user's terminal settings. This prevents concurrent sudo
processes from restoring the terminal settings to the wrong values.
GitHub issue #312.
* Reverted a change from sudo 1.9.4 that resulted in PAM session
modules being called with the environment of the command to be
run instead of the environment of the invoking user.
GitHub issue #318.
* New Indonesian translation from translationproject.org.
* The sudo_logsrvd server will now raise its open file descriptor
limit to the maximum allowed value when it starts up. Each
connection can require up to nine open file descriptors so the
default soft limit may be too low.
* Better log message when rejecting a command if the "intercept"
option is enabled and the "intercept_allow_setid" option is
disabled. Previously, "command not allowed" would be logged and
the user had no way of knowing what the actual problem was.
* Sudo will now log the invoking user's environment as "submitenv"
in the JSON logs. The command's environment ("runenv") is no
longer logged for commands rejected by the sudoers file or an
approval plugin.
* Tue Nov 21 2023 Dominique Leuenberger <[email protected]>
- Package/ship empty /etc/sudoers.d directory for admins to
discover where to put their won config.
* Wed Sep 20 2023 Ludwig Nussel <[email protected]>
- Introduce optional wheel and sudo group policies as separate packages
(bsc#1203978, jsc#PED-260)
* Thu Sep 14 2023 Otto Hollmann <[email protected]>
- Install config files into /usr/etc and read from both location:
/etc and /usr/etc (bsc#1205118)
* Tue Sep 12 2023 Otto Hollmann <[email protected]>
- Update to 1.9.14p3:
* Fixed a crash with Python 3.12 when the sudo Python python is unloaded.
This only affects make check for the Python plugin.
* Adapted the sudo Python plugin test output to match Python 3.12.
- Update to 1.9.14p2:
* Fixed a crash on Linux systems introduced in version 1.9.14 when running a
command with a NULL argv[0] if log_subcmds or intercept is enabled in
sudoers.
* Fixed a problem with "stair-stepped" output when piping or redirecting the
output of a sudo command that takes user input when running a command in
a pseudo-terminal.
* Fixed a bug introduced in sudo 1.9.14 that affects matching sudoers rules
containing a Runas_Spec with an empty Runas user. These rules should only
match when sudo’s -g option is used but were matching even without the -g
option. #290.
* Wed Jul 12 2023 Paolo Stivanin <[email protected]>
- Update to 1.9.14p1:
* Fixed an invalid free bug in sudo_logsrvd that was introduced
in version 1.9.14 which could cause sudo_logsrvd to crash.
* The sudoers plugin no longer tries to send the terminal name
to the log server when no terminal is present. This bug was
introduced in version 1.9.14.
* Fixed a bug where if the "intercept" or "log_subcmds" sudoers
option was enabled and a sub-command was run where the first
entry of the argument vector didn't match the command being run.
This resulted in commands like "sudo su -" being killed due to
the mismatch. Bug #1050.
* The sudoers plugin now canonicalizes command path names before
matching (where possible). This fixes a bug where sudo could
execute the wrong path if there are multiple symbolic links with
the same target and the same base name in sudoers that a user is
allowed to run. GitHub issue #228.
* Improved command matching when a chroot is specified in sudoers.
The sudoers plugin will now change the root directory id needed
before performing command matching. Previously, the root directory
was simply prepended to the path that was being processed.
* When NETGROUP_BASE is set in the ldap.conf file, sudo will now
perform its own netgroup lookups of the host name instead of
using the system innetgr(3) function. This guarantees that user
and host netgroup lookups are performed using the same LDAP
server (or servers).
* Fixed a bug introduced in sudo 1.9.13 that resulted in a missing
" ; " separator between environment variables and the command
in log entries.
* The visudo utility now displays a warning when it ignores a file
in an include dir such as /etc/sudoers.d.
* When running a command in a pseudo-terminal, sudo will initialize
the terminal settings even if it is the background process.
Previously, sudo only initialized the pseudo-terminal when running
in the foreground. This fixes an issue where a program that
checks the window size would read the wrong value when sudo was
running in the background.
* Fixed a bug where only the first two digits of the TSID field
being was logged. Bug #1046.
* The "log_pty" sudoers option is now enabled by default. To
restore the historic behavior where a command is run in the
user's terminal, add "Defaults !use_pty" to the sudoers file.
GitHub issue #258.
* Sudo's "-b" option now works when the command is run in a
pseudo-terminal.
* When disabling core dumps, sudo now only modifies the soft limit
and leaves the hard limit as-is. This avoids problems on Linux
when sudo does not have CAP_SYS_RESOURCE, which may be the case
when run inside a container. GitHub issue #42.
* Sudo configuration file paths have been converted to colon-separated
lists of paths. This makes it possible to have configuration
files on a read-only file system while still allowing for local
modifications in a different (writable) directory. The new
- -enable-adminconf configure option can be used to specify a
directory that is searched for configuration files in preference
to the sysconfdir (which is usually /etc).
* The "intercept_verify" sudoers option is now only applied when
the "intercept" option is set in sudoers. Previously, it was
also applied when "log_subcmds" was enabled.
* The NETGROUP_QUERY ldap.conf parameter can now be disabled for
LDAP servers that do not support querying the nisNetgroup object
by its nisNetgroupTriple attribute, while still allowing sudo to
query the LDAP server directly to determine netgroup membership.
* Fixed a long-standing bug where a sudoers rule without an explicit
runas list allowed the user to run a command as root and any
group instead of just one of the groups that root is a member
of. For example, a rule such as "myuser ALL = ALL" would permit
"sudo -u root -g othergroup" even if root did not belong to
"othergroup".
* Fixed a bug where a sudoers rule with an explicit runas list
allowed a user to run sudo commands as themselves. For example,
a rule such as "myuser ALL = (root) ALL", "myuser" should only
allow commands to be run as root (optionally using one of root's
groups). However, the rule also allowed the user to run
"sudo -u myuser -g myuser command".
* Fixed a bug that prevented the user from specifying a group on
the command line via "sudo -g" if the rule's Runas_Spec contained
a Runas_Alias.
* Sudo now requires a C compiler that conforms to ISO C99 or higher
to build.

* Thu Mar 09 2023 Jason Sikes <[email protected]>
- Update to 1.9.13p3:
Fixed a bug introduced in sudo 1.9.13 that caused a syntax error
when list was used as a user or host name. GitHub issue #246.
Fixed a bug that could cause sudo to hang when running a command
in a pseudo-terminal when there is still input buffered after a
command has exited. [bsc#1203201]
Fixed sudo -U otheruser -l command. This is a regression in
sudo 1.9.13. GitHub issue #248.
Fixed sudo -l command args when matching a command in sudoers
with command line arguments. This is a regression in sudo 1.9.13.
GitHub issue #249.
* Tue Feb 28 2023 Jason Sikes <[email protected]>
- Update to 1.9.13p2 (bsc#1208595, CVE-2023-27320):
Fixed the --enable-static-sudoers option, broken in sudo 1.9.13.
GitHub issue #245.
Fixed a potential double-free bug when matching a sudoers rule
that contains a per-command chroot directive (CHROOT=dir).
This bug was introduced in sudo 1.9.8.
* Sun Feb 19 2023 Jason Sikes <[email protected]>
- Update to 1.9.13p1:
Fixed a typo in the configure script that resulted in a line like
“]: command not found” in the output. GitHub issue #238.
Corrected the order of the C23 [[noreturn]] attribute in function
prototypes. This fixes a build error with GCC 13. GitHub issue #239.
The check make target misbehaved when there was more than one
version of the UTF-8 C locale in the output of locale -a.
GitHub issue #241.
Removed a dependency on the AC_SYS_YEAR2038 macro in configure.ac.
This was added in autoconf 2.72 but sudo’s configure.ac only
required autoconf 2.70. GitHub issue #242.
Relaxed the autoconf version requirement to version 2.69.
* Wed Feb 15 2023 Jason Sikes <[email protected]>
- Update to 1.9.13:
* Changes in 1.9.13:
Fixed a bug running relative commands via sudo when log_subcmds
is enabled. GitHub issue #194.
Fixed a signal handling bug when running sudo commands in a shell
script. Signals were not being forwarded to the command when the
sudo process was not run in its own process group.
Fixed a bug in the cvtsudoers LDIF parsing when the file ends without
a newline and a backslash is the last character of the file.
Fixed a potential use-after-free bug with cvtsudoers filtering.
GitHub issue #198.
Added a reminder to the default lecture that the password will not
echo. This line is only displayed when the pwfeedback option is
disabled. GitHub issue #195.
Fixed potential memory leaks in error paths. GitHub issue #199.
GitHub issue #202.
Fixed potential NULL dereferences on memory allocation failure.
GitHub issue #204. GitHub issue #211.
Sudo now uses C23-style attributes in function prototypes instead
of gcc-style attributes if supported.
Added a new list pseudo-command in sudoers to allow a user to list
another user’s privileges. Previously, only root or a user with
the ability to run any command as either root or the target user
on the current host could use the -U option. This also includes a
fix to the log entry when a user lacks permission to run
sudo -U otheruser -l command. Previously, the logs would indicate
that the user tried to run the actual command, now the log entry
includes the list operation.
JSON logging now escapes control characters if they happen to
appear in the command or environment.
New Albanian translation from translationproject.org.
Regular expressions in sudoers or logsrvd.conf may no longer contain
consecutive repetition operators. This is implementation- specific
behavior according to POSIX, but some implementations will allocate
excessive amounts of memory. This mainly affects the fuzzers.
Sudo now builds AIX-style shared libraries and dynamic shared
objects by default instead of svr4-style. This means that the
default sudo plugins are now .a (archive) files that contain a .so
shared object file instead of bare .so files. This was done to
improve compatibility with the AIX Freeware ecosystem, specifically,
the AIX Freeware build of OpenSSL. Sudo will still load
svr4-style .so plugins and if a .so file is requested, either via
sudo.conf or the sudoers file, and only the .a file is present,
sudo will convert the path from plugin.so to plugin.a(plugin.so)
when loading it. This ensures compatibility with existing
configurations. To restore the old, pre-1.9.13 behavior, run
configure using the –with-aix-soname=svr4 option.
Sudo no longer checks the ownership and mode of the plugins that
it loads. Plugins are configured via either the sudo.conf or
sudoers file which are trusted configuration files. These checks
suffered from time-of-check vs. time-of-use race conditions and
complicate loading plugins that are not simple paths. Ownership
and mode checks are still performed when loading the sudo.conf
and sudoers files, which do not suffer from race conditions.
The sudo.conf developer_mode setting is no longer used.
Control characters in sudo log messages and sudoreplay -l output
are now escaped in octal format. Space characters in the command
path are also escaped. Command line arguments that contain spaces
are surrounded by single quotes and any literal single quote or
backslash characters are escaped with a backslash. This makes it
possible to distinguish multiple command line arguments from a
single argument that contains spaces.
Improved support for DragonFly BSD which uses a different
struct procinfo than either FreeBSD or 4.4BSD.
Fixed a compilation error on Linux arm systems running older
kernels that may not define EM_ARM in linux/elf-em.h.
GitHub issue #232.
Fixed a compilation error when LDFLAGS contains -Wl,–no-undefined.
Sudo will now link using -Wl,–no-undefined by default if possible.
GitHub issue #234.
Fixed a bug executing a command with a very long argument vector
when log_subcmds or intercept is enabled on a system where
intercept_type is set to trace. GitHub issue #194.
When sudo is configured to run a command in a pseudo-terminal but
the standard input is not connected to a terminal, the command
will now be run as a background process. This works around a problem
running sudo commands in the background from a shell script where
changing the terminal to raw mode could interfere with the interactive
shell that ran the script. GitHub issue #237.
A missing include file in sudoers is no longer a fatal error unless
the error_recovery plugin argument has been set to false.
* Thu Jan 19 2023 Jason Sikes <[email protected]>
- Update to 1.9.12p2:
* Fixes bsc#1207082
* Changes in 1.9.12p2:
Fixed a compilation error on Linux/aarch64. GitHub issue #197.
Fixed a potential crash introduced in the fix GitHub issue #134.
If a user’s sudoers entry did not have any RunAs user’s set,
running sudo -U otheruser -l would dereference a NULL pointer.
Fixed a bug introduced in sudo 1.9.12 that could prevent sudo
from creating a I/O files when the iolog_file sudoers setting
contains six or more Xs.
Fixed a compilation issue on AIX with the native compiler.
GitHub issue #231.
Fixed CVE-2023-22809, a flaw in sudo’s -e option (aka sudoedit)
that could allow a malicious user with sudoedit privileges to
edit arbitrary files. For more information, see Sudoedit can
edit arbitrary files.
* Mon Nov 21 2022 Jason Sikes <[email protected]>
- Update to 1.9.12p1:
* Changes in 1.9.12p1:
- Sudo’s configure script now does a better job of detecting when
the -fstack-clash-protection compiler option does not work.
GitHub issue #191.
- Fixed CVE-2022-43995, a potential out-of-bounds write for passwords
smaller than 8 characters when passwd authentication is enabled.
This does not affect configurations that use other authentication
methods such as PAM, AIX authentication or BSD authentication.
- Fixed a build error with some configurations compiling host_port.c.
* Dropped sudo-CVE-2022-43995.patch
* Thu Nov 03 2022 Jason Sikes <[email protected]>
- Added sudo-CVE-2022-43995.patch
* CVE-2022-43995
* bsc#1204986
* Fixed a potential heap-based buffer over-read when entering a password
of seven characters or fewer and using the crypt() password backend.
* Tue Oct 25 2022 Jason Sikes <[email protected]>
- Update to 1.9.12:
* Dropped sudo-1.9.10-update_sudouser_to_utf8.patch
* Changes in Sudo 1.9.12:
* Fixed a bug when logging the command’s exit status in intercept mode.
The wrong command could be logged with the exit status.
* For ptrace-based intercept mode, sudo will now attempt to verify that
the command path name, arguments and environment have not changed from
the time when they were authorized by the security policy. The new
intercept_verify sudoers setting can be used to control this behavior.
* Fixed running commands with a relative path (e.g. ./foo) in intercept
mode. Previously, this would fail if sudo’s current working directory
was different from that of the command.
* Sudo now supports passing the execve(2) system call the NULL pointer
for the argv and/or envp arguments when in intercept mode. Linux treats
a NULL pointer like an empty array.
* The sudoers LDAP schema now allows sudoUser, sudoRunasUser and
sudoRunasGroup to include UTF-8 characters, not just 7-bit ASCII.
* Fixed a problem with sudo -i on SELinux when the target user’s home
directory is not searchable by sudo. GitHub issue #160.
* Neovim has been added to the list of visudo editors that support passing
the line number on the command line.
* Fixed a bug in sudo’s SHA384 and SHA512 message digest padding.
* Added a new -N (no-update) command line option to sudo which can be used
to prevent sudo from updating the user’s cached credentials. It is now
possible to determine whether or not a user’s cached credentials are
currently valid by running:
$ sudo -Nnv
and checking the exit value. One use case for this is to indicate in a
shell prompt that sudo is “active” for the user.
* PAM approval modules are no longer invoked when running sub-commands in
intercept mode unless the intercept_authenticate option is set. There is
a substantial performance penalty for calling into PAM for each command
run. PAM approval modules are still called for the initial command.
* Intercept mode on Linux now uses process_vm_readv(2) and process_vm_writev(2)
if available.
* The XDG_CURRENT_DESKTOP environment variable is now preserved by default.
This makes it possible for graphical applications to choose the correct
theme when run via sudo.
* On 64-bit systems, if sudo fails to load a sudoers group plugin, it will
use system-specific heuristics to try to locate a 64-bit version of the plugin.
* The cvtsudoers manual now documents the JSON and CSV output formats.
GitHub issue #172.
* Fixed a bug where sub-commands were not being logged to a remote log server
when log_subcmds was enabled. GitHub issue #174.
* The new log_stdin, log_stdout, log_stderr, log_ttyin, and log_ttyout
sudoers settings can be used to support more fine-grained I/O logging.
The sudo front-end no longer allocates a pseudo-terminal when running a
command if the I/O logging plugin requests logging of stdin, stdout, or
stderr but not terminal input/output.
* Quieted a libgcrypt run-time initialization warning. This fixes Debian
bug #1019428 and Ubuntu bug #1397663.
* Fixed a bug in visudo that caused literal backslashes to be removed from
the EDITOR environment variable. GitHub issue #179.
* The sudo Python plugin now implements the find_spec method instead of the
the deprecated find_module. This fixes a test failure when a newer version
of setuptools that doesn’t include find_module is found on the system.
* Fixed a bug introduced in sudo 1.9.9 where sudo_logsrvd created the process
ID file, usually /var/run/sudo/sudo_logsrvd.pid, as a directory instead of a
plain file. The same bug could result in I/O log directories that end in six
or more X’s being created literally in addition to the name being used as a
template for the mkdtemp(3) function.
* Fixed a long-standing bug where a sudoers rule with a command line argument
of “”, which indicates the command may be run with no arguments, would also
match a literal "" on the command line. GitHub issue #182.
* Added the -I option to visudo which only edits the main sudoers file. Include
files are not edited unless a syntax error is found.
* Fixed sudo -l -U otheruser output when the runas list is empty. Previously,
sudo would list the invoking user instead of the list user. GitHub issue #183.
* Fixed the display of command tags and options in sudo -l output when the RunAs
user or group changes. A new line is started for RunAs changes which means we
need to display the command tags and options again. GitHub issue #184.
* The sesh helper program now uses getopt_long(3) to parse the command line options.
* The embedded copy of zlib has been updated to version 1.2.13.
* Fixed a bug that prevented event log data from being sent to the log server when
I/O logging was not enabled. This only affected systems without PAM or
configurations where the pam_session and pam_setcred options were disabled in
the sudoers file.
* Fixed a bug where sudo -l output included a carriage return after the newline.
This is only needed when displaying to a terminal in raw mode. Bug #1042.
* Sat Sep 10 2022 Jason Sikes <[email protected]>
- Modified sudo-sudoers.patch
* bsc#1177578
* Removed redundant and confusing 'secure_path' settings in
sudo-sudoers file.
* Sat Aug 20 2022 Jason Sikes <[email protected]>
- Update to 1.9.11p3:
* Changes in Sudo 1.9.11
* Fixed a crash in the Python module with Python 3.9.10 on some systems.
Additionally, make check now passes for Python 3.9.10.
* Error messages sent via email now include more details, including the file
name and the line number and column of the error. Multiple errors are sent in
a single message. Previously, only the first error was included.
* Fixed logging of parse errors in JSON format. Previously, the JSON logger would
not write entries unless the command and runuser were set. These may not be
known at the time a parse error is encountered.
* Fixed a potential crash parsing sudoers lines larger than twice the value of
LINE_MAX on systems that lack the getdelim() function.
* The tests run by make check now unset the LANGUAGE environment variable.
Otherwise, localization strings will not match if LANGUAGE is set to a
non-English locale. Bug #1025.
* The “starttime” test now passed when run under Debian faketime. Bug #1026.
* The Kerberos authentication module now honors the custom password prompt if one
has been specified.
* The embedded copy of zlib has been updated to version 1.2.12.
* Updated the version of libtool used by sudo to version 2.4.7.
* Sudo now defines _TIME_BITS to 64 on systems that define __TIMESIZE in the
header files (currently only GNU libc). This is required to allow the use of
64-bit time values on some 32-bit systems.
* Sudo’s intercept and log_subcmds options no longer force the command to run in
its own pseudo-terminal. It is now also possible to intercept the system(3) function.
* Fixed a bug in sudo_logsrvd when run in store-first relay mode where the commit
point messages sent by the server were incorrect if the command was suspended
or received a window size change event.
* Fixed a potential crash in sudo_logsrvd when the tls_dhparams configuration
setting was used.
* The intercept and log_subcmds functionality can now use ptrace(2) on Linux
systems that support seccomp(2) filtering. This has the advantage of working
for both static and dynamic binaries and can work with sudo’s SELinux RBAC mode.
The following architectures are currently supported: i386, x86_64, aarch64, arm,
mips (log_subcmds only), powerpc, riscv, and s390x. The default is to use
ptrace(2) where possible; the new intercept_type sudoers setting can be used
to explicitly set the type.
* New Georgian translation from translationproject.org.
* Fixed creating packages on CentOS Stream.
* Fixed a bug in the intercept and log_subcmds support where the execve(2)
wrapper was using the current environment instead of the passed environment
pointer. Bug #1030.
* Added AppArmor integration for Linux. A sudoers rule can now specify an
APPARMOR_PROFILE option to run a command confined by the named AppArmor profile.
* Fixed parsing of the server_log setting in sudo_logsrvd.conf. Non-paths were
being treated as paths and an actual path was treated as an error.
* Changes in Sudo 1.9.11p1:
* Correctly handle EAGAIN in the I/O read/right events. This fixes a hang seen on
some systems when piping a large amount of data through sudo, such as via rsync.
Bug #963.
* Changes to avoid implementation or unspecified behavior when bit shifting signed
values in the protobuf library.
* Fixed a compilation error on Linux/aarch64.
* Fixed the configure check for seccomp(2) support on Linux.
* Corrected the EBNF specification for tags in the sudoers manual page.
GitHub issue #153.
* Changes in Sudo 1.9.11p2:
* Fixed a compilation error on Linux/x86_64 with the x32 ABI.
* Fixed a regression introduced in 1.9.11p1 that caused a warning when logging to
sudo_logsrvd if the command returned no output.
* Changes in Sudo 1.9.11p3:
* Fixed “connection reset” errors on AIX when running shell scripts with the intercept
or log_subcmds sudoers options enabled. Bug #1034.
* Fixed very slow execution of shell scripts when the intercept or log_subcmds sudoers
options are set on systems that enable Nagle’s algorithm on the loopback device,
such as AIX. Bug #1034.
* Modified sudo-sudoers.patch

- update to 1.9.10:
* Added new log_passwords and passprompt_regex sudoers options. If
log_passwords is disabled, sudo will attempt to prevent passwords from being
logged. If sudo detects any of the regular expressions in the passprompt_regex
list in the terminal output, sudo will log ‘*’ characters instead of the
terminal input until a newline or carriage return is found in the input or an
output character is received.
* Added new log_passwords and passprompt_regex settings to sudo_logsrvd that
operate like the sudoers options when logging terminal input.
* Fixed several few bugs in the cvtsudoers utility when merging multiple sudoers
sources.
* Fixed a bug in sudo_logsrvd parsing the sudo_logsrvd.conf file, where the
retry_interval in the [relay] section was not being recognized.
* Restored the pre-1.9.9 behavior of not performing authentication when sudo’s -n
option is specified. A new noninteractive_auth sudoers option has been added to
enable PAM authentication in non-interactive mode. GitHub issue #131.
* On systems with /proc, if the /proc/self/stat (Linux) or /proc/pid/psinfo
(other systems) file is missing or invalid, sudo will now check file
descriptors 0-2 to determine the user’s terminal. Bug #1020.
* Fixed a compilation problem on Debian kFreeBSD. Bug #1021.
* Fixed a crash in sudo_logsrvd when running in relay mode if an alert message is
received.
* Fixed an issue that resulting in “problem with defaults entries” email to be
sent if a user ran sudo when the sudoers entry in the nsswitch.conf file
includes “sss” but no sudo provider is configured in /etc/sssd/sssd.conf.
* Updated the warning displayed when the invoking user is not allowed to run
sudo. If sudo has been configured to send mail on failed attempts (see the
mail_* flags in sudoers), it will now print “This incident has been reported to
the administrator.” If the mailto or mailerpath sudoers settings are disabled,
the message will not be printed and no mail will be sent.
* Fixed a bug where the user-specified command timeout was not being honored if
the sudoers rule did not also specify a timeout.
* Added support for using POSIX extended regular expressions in sudoers rules. A
command and/or arguments in sudoers are treated as a regular expression if they
start with a ‘^’ character and end with a ‘$’. The command and arguments are
matched separately, either one (or both) may be a regular expression.
* A user may now only run sudo -U otheruser -l if they have a “sudo ALL”
privilege where the RunAs user contains either root or otheruser. Previously,
having “sudo ALL” was sufficient, regardless of the RunAs user. GitHub issue
[#134].
* The sudo lecture is now displayed immediately before the password prompt. As a
result, sudo will no longer display the lecture unless the user needs to enter
a password. Authentication methods that don’t interact with the user via a
terminal do not trigger the lecture.
* Sudo now uses its own closefrom() emulation on Linux systems. The glibc version
may not work in a chroot jail where /proc is not available. If close_range(2)
is present, it will be used in preference to /proc/self/fd.

- Update to 1.9.9
* Sudo can now be built with OpenSSL 3.0 without generating
warnings about deprecated OpenSSL APIs.
* A digest can now be specified along with the ALL command in
the LDAP and SSSD back-ends. Sudo 1.9.0 introduced support for
this in the sudoers file but did not include corresponding
changes for the other back-ends.
* visudo now only warns about an undefined alias or a cycle in
an alias once for each alias.
* The sudoRole cn was truncated by a single character in warning
messages. GitHub issue #115.
* The cvtsudoers utility has new --group-file and --passwd-file
options to use a custom passwd or group file when the
- -match-local option is also used.
* The cvtsudoers utility can now filter or match based on a command.
* The cvtsudoers utility can now produce output in csv
(comma-separated value) format. This can be used to help generate
entitlement reports.
* Fixed a bug in sudo_logsrvd that could result in the connection
being dropped for very long command lines.
* Fixed a bug where sudo_logsrvd would not accept a restore point
of zero.
* Fixed a bug in visudo where the value of the editor setting was
not used if it did not match the user’s EDITOR environment
variable. This was only a problem if the env_editor setting was
not enabled. Bug #1000.
* Sudo now builds with the -fcf-protection compiler option and the
- z now linker option if supported.
* The output of sudoreplay -l now more closely matches the
traditional sudo log format.
* The sudo_sendlog utility will now use the full contents of the
log.json file, if present. This makes it possible to send
sudo-format I/O logs that use the newer log.json format to
sudo_logsrvd without losing any information.
* Fixed compilation of the arc4random_buf() replacement on systems
with arc4random() but no arc4random_buf(). Bug #1008.
* Sudo now uses its own getentropy() by default on Linux. The GNU
libc version of getentropy() will fail on older kernels that
don’t support the getrandom() system call.
* It is now possible to build sudo with WolfSSL’s OpenSSL
compatibility layer by using the --enable-wolfssl configure
option.
* Fixed a bug related to Daylight Saving Time when parsing
timestamps in Generalized Time format. This affected the NOTBEFORE
and NOTAFTER options in sudoers. Bug #1006.
* Added the -O and -P options to visudo, which can be used to check
or set the owner and permissions. This can be used in conjunction
with the -c option to check that the sudoers file ownership and
permissions are correct. Bug #1007.
* It is now possible to set resource limits in the sudoers file
itself. The special values default and “user” refer to the
default system limit and invoking user limit respectively. The
core dump size limit is now set to 0 by default unless overridden
by the sudoers file.
* The cvtsudoers utility can now merge multiple sudoers sources into
a single, combined sudoers file. If there are conflicting entries,
cvtsudoers will attempt to resolve them but manual intervention
may be required. The merging of sudoers rules is currently fairly
simplistic but will be improved in a future release.
* Sudo was parsing but not applying the “deref” and “tls_reqcert”
ldap.conf settings. This meant the options were effectively ignored
which broke dereferencing of aliases in LDAP. Bug #1013.
* Clarified in the sudo man page that the security policy may
override the user’s PATH environment variable. Bug #1014.
* When sudo is run in non-interactive mode (with the -n option), it
will now attempt PAM authentication and only exit with an error if
user interaction is required. This allows PAM modules that don’t
interact with the user to succeed. Previously, sudo would not
attempt authentication if the -n option was specified. Bug #956
and GitHub issue #83.
* Fixed a regression introduced in version 1.9.1 when sudo is built
with the --with-fqdn configure option. The local host name was
being resolved before the sudoers file was processed, making it
impossible to disable DNS lookups by negating the fqdn sudoers
option. Bug #1016.
* Added support for negated sudoUser attributes in the LDAP and SSSD
sudoers back ends. A matching sudoUser that is negated will cause
the sudoRole containing it to be ignored.
* Fixed a bug where the stack resource limit could be set to a value
smaller than that of the invoking user and not be reset before the
command was run. Bug #1016.

- update to 1.9.8p2
* Fixed a potential out-of-bounds read with "sudo -i" when the
target user's shell is bash. This is a regression introduced
in sudo 1.9.8. Bug #998.
* sudo_logsrvd now only sends a log ID for first command of a session.
There is no need to send the log ID for each sub-command.
* Fixed a few minor memory leaks in intercept mode.
* Fixed a problem with sudo_logsrvd in relay mode if "store_first"
was enabled when handling sub-commands. A new zero-length journal
file was created for each sub-command instead of simply using
the existing journal file.
- update to 1.9.8p1
* Fixed support for passing a prompt (sudo -p) or a login class
(sudo -l) on the command line. This is a regression introduced
in sudo 1.9.8. Bug #993.
* Fixed a crash with "sudo ALL" rules in the LDAP and SSSD back-ends.
This is a regression introduced in sudo 1.9.8. Bug #994.
* Fixed a compilation error when the --enable-static-sudoers configure
option was specified. This is a regression introduced in sudo
1.9.8 caused by a symbol clash with the intercept and log server
protobuf functions.
* It is now possible to transparently intercepting sub-commands
executed by the original command run via sudo. Intercept support
is implemented using LD_PRELOAD (or the equivalent supported by
the system) and so has some limitations. The two main limitations
are that only dynamic executables are supported and only the
execl, execle, execlp, execv, execve, execvp, and execvpe library
functions are currently intercepted. Its main use case is to
support restricting privileged shells run via sudo.
To support this, there is a new "intercept" Defaults setting and
an INTERCEPT command tag that can be used in sudoers. For example:
Cmnd_Alias SHELLS=/bin/bash, /bin/sh, /bin/csh, /bin/ksh, /bin/zsh
Defaults!SHELLS intercept
would cause sudo to run the listed shells in intercept mode.
This can also be set on a per-rule basis. For example:
Cmnd_Alias SHELLS=/bin/bash, /bin/sh, /bin/csh, /bin/ksh, /bin/zsh
chuck ALL = INTERCEPT: SHELLS
would only apply intercept mode to user "chuck" when running one
of the listed shells.
In intercept mode, sudo will not prompt for a password before
running a sub-command and will not allow a set-user-ID or
set-group-ID program to be run by default. The new
intercept_authenticate and intercept_allow_setid sudoers settings
can be used to change this behavior.
* The new "log_subcmds" sudoers setting can be used to log additional
commands run in a privileged shell. It uses the same mechanism as
the intercept support described above and has the same limitations.
* The new "log_exit_status" sudoers setting can be used to log
the exit status commands run via sudo. This is also a corresponding
"log_exit" setting in the sudo_logsrvd.conf eventlog stanza.
* Support for logging sudo_logsrvd errors via syslog or to a file.
Previously, most sudo_logsrvd errors were only visible in the
debug log.
* Better diagnostics when there is a TLS certificate validation error.
* Using the "+=" or "-=" operators in a Defaults setting that takes
a string, not a list, now produces a warning from sudo and a
syntax error from inside visudo.
* Fixed a bug where the "iolog_mode" setting in sudoers and sudo_logsrvd
had no effect when creating I/O log parent directories if the I/O log
file name ended with the string "XXXXXX".
* Fixed a bug in the sudoers custom prompt code where the size
parameter that was passed to the strlcpy() function was incorrect.
No overflow was possible since the correct amount of memory was
already pre-allocated.
* The mksigname and mksiglist helper programs are now built with
the host compiler, not the target compiler, when cross-compiling.
Bug #989.
* Fixed compilation error when the --enable-static-sudoers configure
option was specified. This was due to a typo introduced in sudo
1.9.7. GitHub PR #113.

- update to 1.9.7p2

recording collection (without it's clear text)
- fixed SLES12 build
* When formatting JSON output, octal numbers are now stored as
strings, not numbers. The JSON spec does not actually support
octal numbers with a '0' prefix.
* Fixed a compilation issue on Solaris 9.
* Sudo now can handle the getgroups() function returning a different
number of groups for subsequent invocations. GitHub PR #106.
* When loading a Python plugin, python_plugin.so now verifies
that the module loaded matches the one we tried to load. This
allows sudo to display a more useful error message when trying
to load a plugin with a name that conflicts with a Python module
installed in the system location.
* Sudo no longer sets the the open files resource limit to "unlimited"
while it runs. This avoids a problem where sudo's closefrom()
emulation would need to close a very large number of descriptors
on systems without a way to determine which ones are actually open.
* Sudo now includes a configure check for va_copy or __va_copy and
only defines its own version if the configure test fails.
* Fixed a bug in sudo's utmp file handling which prevented old
entries from being reused. As a result, the utmp (or utmpx)
file was appended to unnecessarily. GitHub PR #108.
* Fixed a bug introduced in sudo 1.9.7 that prevented sudo_logsrvd
from accepting TLS connections when OpenSSL is used. Bug #988.
* Fixed an SELinux sudoedit bug when the edited temporary file
could not be opened. The sesh helper would still be run even
when there are no temporary files available to install.
* Fixed a compilation problem on FreeBSD.
* The sudo_noexec.so file is now built as a module on all systems
other than macOS. This makes it possible to use other libtool
implementations such as slibtool. On macOS shared libraries and
modules are not interchangeable and the version of libtool shipped
with sudo must be used.
* Fixed a few bugs in the getgrouplist() emulation on Solaris when
reading from the local group file.
* Fixed a bug in sudo_logsrvd that prevented periodic relay server
connection retries from occurring in "store_first" mode.
* Disabled the nss_search()-based getgrouplist() emulation on HP-UX
due to a crash when the group source is set to "compat" in
/etc/nsswitch.conf. This is probably due to a mismatch between
include/compat/nss_dbdefs.h and what HP-UX uses internally. On
HP-UX we now just cycle through groups the slow way using
getgrent(). Bug #978.

- update to 1.9.7
* The "fuzz" Makefile target now runs all the fuzzers for 8192
passes (can be overridden via the FUZZ_RUNS variable). This makes
it easier to run the fuzzers in-tree. To run a fuzzer indefinitely,
set FUZZ_RUNS=-1, e.g. "make FUZZ_RUNS=-1 fuzz".
* Fixed fuzzing on FreeBSD where the ld.lld linker returns an
error by default when a symbol is multiply-defined.
* Added support for determining local IPv6 addresses on systems
that lack the getifaddrs() function. This now works on AIX,
HP-UX and Solaris (at least). Bug #969.
* Fixed a bug introduced in sudo 1.9.6 that caused "sudo -V" to
report a usage error. Also, when invoked as sudoedit, sudo now
allows a more restricted set of options that matches the usage
statement and documentation. GitHub issue #95.
* Fixed a crash in sudo_sendlog when the specified certificate
or key does not exist or is invalid. Bug #970
* Fixed a compilation error when sudo is configured with the
- -disable-log-client option.
* Sudo's limited support for SUCCESS=return entries in nsswitch.conf
is now documented. Bug #971.
* Sudo now requires autoconf 2.70 or higher to regenerate the
configure script. Bug #972.
* sudo_logsrvd now has a relay mode which can be used to create
a hierarchy of log servers. By default, when a relay server is
defined, messages from the client are forwarded immediately to
the relay. However, if the "store_first" setting is enabled,
the log will be stored locally until the command completes and
then relayed. Bug #965.
* Sudo now links with OpenSSL by default if it is available unless
the --disable-openssl configure option is used or both the
- -disable-log-client and --disable-log-server configure options
are specified.
* Fixed configure's Python version detection when the version minor
number is more than a single digit, for example Python 3.10.
* The sudo Python module tests now pass for Python 3.10.
* Sudo will now avoid changing the datasize resource limit
as long as the existing value is at least 1GB. This works around
a problem on 64-bit HP-UX where it is not possible to exactly
restore the original datasize limit. Bug #973.
* Fixed a race condition that could result in a hang when sudo is
executed by a process where the SIGCHLD handler is set to SIG_IGN.
This fixes the bug described by GitHub PR #98.
* Fixed an out-of-bounds read in sudoedit and visudo when the
EDITOR, VISUAL or SUDO_EDITOR environment variables end in an
unescaped backslash. Also fixed the handling of quote characters
that are escaped by a backslash. GitHub issue #99.
* Fixed a bug that prevented the "log_server_verify" sudoers option
from taking effect.
* The sudo_sendlog utility has a new -s option to cause it to stop
sending I/O records after a user-specified elapsed time. This
can be used to test the I/O log restart functionality of sudo_logsrvd.
* Fixed a crash introduced in sudo 1.9.4 in sudo_logsrvd when
attempting to restart an interrupted I/O log transfer.
* The TLS connection timeout in the sudoers log client was previously
hard-coded to 10 seconds. It now uses the value of log_server_timeout.
* The configure script now outputs a summary of the user-configurable
options at the end, separate from output of configure script tests.
Bug #820.
* Corrected the description of which groups may be specified via the
- g option in the Runas_Spec section. Bug #975.
* Sat Mar 20 2021 Dirk Müller <[email protected]>
- update to 1.9.6p1
* Fixed a regression introduced in sudo 1.9.6 that resulted in an
error message instead of a usage message when sudo is run with
no arguments.
* Fixed a sudo_sendlog compilation problem with the AIX xlC compiler.
* Fixed a regression introduced in sudo 1.9.4 where the
- -disable-root-mailer configure option had no effect.
* Added a --disable-leaks configure option that avoids some
memory leaks on exit that would otherwise occur. This is intended
to be used with development tools that measure memory leaks. It
is not safe to use in production at this time.
* Plugged some memory leaks identified by oss-fuzz and ASAN.
* Fixed the handling of sudoOptions for an LDAP sudoRole that
contains multiple sudoCommands. Previously, some of the options
would only be applied to the first sudoCommand.
* Fixed a potential out of bounds read in the parsing of NOTBEFORE
and NOTAFTER sudoers command options (and their LDAP equivalents).
* The parser used for reading I/O log JSON files is now more
resilient when processing invalid JSON.
* Fixed typos that prevented "make uninstall" from working.
* Fixed a regression introduced in sudo 1.9.4 where the last line
in a sudoers file might not have a terminating NUL character
added if no newline was present.
* Integrated oss-fuzz and LLVM's libFuzzer with sudo. The new
- -enable-fuzzer configure option can be combined with the
- -enable-sanitizer option to build sudo with fuzzing support.
Multiple fuzz targets are available for fuzzing different parts
of sudo. Fuzzers are built and tested via "make fuzz" or as part
of "make check" (even when sudo is not built with fuzzing support).
Fuzzing support currently requires the LLVM clang compiler (not gcc).
* Fixed the --enable-static-sudoers configure option.
* Fixed a potential out of bounds read sudo when is run by a user
with more groups than the value of "max_groups" in sudo.conf.
* Added an "admin_flag" sudoers option to make the use of the
~/.sudo_as_admin_successful file configurable on systems where
sudo is build with the --enable-admin-flag configure option.
This mostly affects Ubuntu and its derivatives.
* The "max_groups" setting in sudo.conf is now limited to 1024.
This setting is obsolete and should no longer be needed.
* Fixed a bug in the tilde expansion of "CHROOT=dir" and "CWD=dir"
sudoers command options. A path "~/foo" was expanded to
"/home/userfoo" instead of "/home/user/foo". This also affects
the runchroot and runcwd Defaults settings.
* Fixed a bug on systems without a native getdelim(3) function
where very long lines could cause parsing of the sudoers file
to end prematurely.
* Fixed a potential integer overflow when converting the
timestamp_timeout and passwd_timeout sudoers settings to a
timespec struct.
* The default for the "group_source" setting in sudo.conf is now
"dynamic" on macOS. Recent versions of macOS do not reliably
return all of a user's non-local groups via getgroups(2), even
when _DARWIN_UNLIMITED_GETGROUPS is defined.
* Fixed a potential use-after-free in the PAM conversation function.
* Fixed potential redefinition of sys/stat.h macros in sudo_compat.h.
* Wed Jan 27 2021 Simon Lees <[email protected]>
- Update to 1.9.5.p2
* When invoked as sudoedit, the same set of command line
options are now accepted as for sudo -e. The -H and -P
options are now rejected for sudoedit and sudo -e which
matches the sudo 1.7 behavior. This is part of the fix for
CVE-2021-3156.
* Fixed a potential buffer overflow when unescaping backslashes
in the command's arguments. Normally, sudo escapes special
characters when running a command via a shell (sudo -s or
sudo -i). However, it was also possible to run sudoedit with
the -s or -i flags in which case no escaping had actually
been done, making a buffer overflow possible.
This fixes CVE-2021-3156. (bsc#1181090)
* Fixed sudo's setprogname(3) emulation on systems that don't
provide it.
* Fixed a problem with the sudoers log server client where a
partial write to the server could result the sudo process
consuming large amounts of CPU time due to a cycle in the
buffer queue. Bug #954.
* Added a missing dependency on libsudo_util in libsudo_eventlog.
Fixes a link error when building sudo statically.
* The user's KRB5CCNAME environment variable is now preserved
when performing PAM authentication. This fixes GSSAPI
authentication when the user has a non-default ccache.
* Thu Jan 14 2021 Kristyna Streitova <[email protected]>
- Update to 1.9.5.p1
* Fixed a regression introduced in sudo 1.9.5 where the editor run
by sudoedit was set-user-ID root unless SELinux RBAC was in use.
The editor is now run with the user's real and effective user-IDs.
- News in 1.9.5
* Fixed a crash introduced in 1.9.4 when running "sudo -i" as an
unknown user. This is related to but distinct from Bug #948.
* If the "lecture_file" setting is enabled in sudoers, it must now
refer to a regular file or a symbolic link to a regular file.
* Fixed a potential use-after-free bug in sudo_logsrvd when the
server shuts down if there are existing connections from clients
that are only logging events and not session I/O data.
* Fixed a buffer size mismatch when serializing the list of IP
addresses for configured network interfaces. This bug is not
actually exploitable since the allocated buffer is large enough
to hold the list of addresses.
* If sudo is executed with a name other than "sudo" or "sudoedit",
it will now fall back to "sudo" as the program name. This affects
warning, help and usage messages as well as the matching of Debug
lines in the /etc/sudo.conf file. Previously, it was possible
for the invoking user to manipulate the program name by setting
argv[0] to an arbitrary value when executing sudo. (bsc#1180687)
* Sudo now checks for failure when setting the close-on-exec flag
on open file descriptors. This should never fail but, if it
were to, there is the possibility of a file descriptor leak to
a child process (such as the command sudo runs).
* Fixed CVE-2021-23239, a potential information leak in sudoedit
that could be used to test for the existence of directories not
normally accessible to the user in certain circumstances. When
creating a new file, sudoedit checks to make sure the parent
directory of the new file exists before running the editor.
However, a race condition exists if the invoking user can replace
(or create) the parent directory. If a symbolic link is created
in place of the parent directory, sudoedit will run the editor
as long as the target of the link exists. If the target of the
link does not exist, an error message will be displayed. The
race condition can be used to test for the existence of an
arbitrary directory. However, it _cannot_ be used to write to
an arbitrary location. (bsc#1180684)
* Fixed CVE-2021-23240, a flaw in the temporary file handling of
sudoedit's SELinux RBAC support. On systems where SELinux is
enabled, a user with sudoedit permissions may be able to set the
owner of an arbitrary file to the user-ID of the target user.
On Linux kernels that support "protected symlinks", setting
/proc/sys/fs/protected_symlinks to 1 will prevent the bug from
being exploited. For more information see

* Added writability checks for sudoedit when SELinux RBAC is in use.
This makes sudoedit behavior consistent regardless of whether
or not SELinux RBAC is in use. Previously, the "sudoedit_checkdir"
setting had no effect for RBAC entries.
* A new sudoers option "selinux" can be used to disable sudo's
SELinux RBAC support.
* Quieted warnings from PVS Studio, clang analyzer, and cppcheck.
Added suppression annotations for PVS Studio false positives.
