* Mon Sep 02 2024 Jaime Marquínez Ferrándiz <[email protected]>
- Update to version 2.28.9:
Security
* Unlike previously documented, enabling MBEDTLS_PSA_HMAC_DRBG_MD_TYPE does
not cause the PSA subsystem to use HMAC_DRBG: it uses HMAC_DRBG only when
MBEDTLS_PSA_CRYPTO_EXTERNAL_RNG and MBEDTLS_CTR_DRBG_C are disabled.
CVE-2024-45157
Bugfix
* Fix the build in some configurations when check_config.h is not included.
Fix gh#Mbed-TLS/mbedtls#9152.
* Fix issue of redefinition warning messages for _GNU_SOURCE in
entropy_poll.c and sha_256.c. There was a build warning during building for
linux platform. Resolves gh#Mbed-TLS/mbedtls#9026
* Fix error handling when creating a key in a dynamic secure element
(feature enabled by MBEDTLS_PSA_CRYPTO_SE_C). In a low memory condition,
the creation could return PSA_SUCCESS but using or destroying the key would
not work. Fixes gh#Mbed-TLS/mbedtls#8537.
* Fix a memory leak that could occur when failing to process an RSA
key through some PSA functions due to low memory conditions. Document and
enforce the limitation of mbedtls_psa_register_se_key()
to persistent keys. Resolves gh#Mbed-TLS/mbedtls#9253.
- Add fix_calloc-transposed-args.patch
* Sun Mar 31 2024 Jaime Marquínez Ferrándiz <[email protected]>
- Update to version 2.28.8:
Features
* AES-NI is now supported in Windows builds with clang and clang-cl.
Resolves gh#Mbed-TLS/mbedtls#8372.
* Add pc files for pkg-config, e.g.:
pkg-config --cflags --libs (mbedtls|mbedcrypto|mbedx509)
Security
* Passing buffers that are stored in untrusted memory as arguments
to PSA functions is now secure by default.
The PSA core now protects against modification of inputs or exposure
of intermediate outputs during operations. This is currently implemented
by copying buffers.
This feature increases code size and memory usage. If buffers passed to
PSA functions are owned exclusively by the PSA core for the duration of
the function call (i.e. no buffer parameters are in shared memory),
copying may be disabled by setting MBEDTLS_PSA_ASSUME_EXCLUSIVE_BUFFERS.
Note that setting this option will cause input-output buffer overlap to
be only partially supported (gh#Mbed-TLS/mbedtls#3266).
Fixes CVE-2024-28960 boo#1222157 .
Bugfix
* Fix the build with CMake when Everest is enabled through
a user configuration file or the compiler command line. Fixes gh#Mbed-TLS/mbedtls#8165.
* Fix an inconsistency between implementations and usages of __cpuid,
which mainly causes failures when building Windows target using
mingw or clang. Fixes gh#Mbed-TLS/mbedtls#8334 & gh#Mbed-TLS/mbedtls#8332.
* Correct initial capacities for key derivation algorithms: TLS12_PRF,
TLS12_PSK_TO_MS.
* Fix mbedtls_pk_get_bitlen() for RSA keys whose size is not a
multiple of 8. Fixes gh#Mbed-TLS/mbedtls#868.
* Avoid segmentation fault caused by releasing not initialized
entropy resource in gen_key example. Fixes gh#Mbed-TLS/mbedtls#8809.
* Fix missing bitflags in SSL session serialization headers. Their absence
allowed SSL sessions saved in one configuration to be loaded in a
different, incompatible configuration.
* Fix the restoration of the ALPN when loading serialized connection with
the mbedtls_ssl_context_load() API.
* Fully support arbitrary overlap between inputs and outputs of PSA
functions. Note that overlap is still only partially supported when
MBEDTLS_PSA_ASSUME_EXCLUSIVE_BUFFERS is set (gh#Mbed-TLS/mbedtls#3266).
Changes
* Use heap memory to allocate DER encoded public/private key.
This reduces stack usage significantly for writing a public/private
key to a PEM string.
* cmake: Use GnuInstallDirs to customize install directories
Replace custom LIB_INSTALL_DIR variable with standard CMAKE_INSTALL_LIBDIR
variable. For backward compatibility, set CMAKE_INSTALL_LIBDIR if
LIB_INSTALL_DIR is set.
* Wed Jan 31 2024 Martin Pluskal <[email protected]>
- Update to version 2.28.7:
- Resolves CVE-2024-23170 boo#1219336
* Fri Nov 10 2023 Jaime Marquínez Ferrándiz <[email protected]>
- Update to 2.28.6:
Changes:
* Mbed TLS is now released under a dual Apache-2.0 OR GPL-2.0-or-later
license. Users may choose which license they take the code under.
* Sat Oct 07 2023 Jaime Marquínez Ferrándiz <[email protected]>
- Update to 2.28.5:
Features
* The documentation of mbedtls_ecp_group now describes the optimized
representation of A for some curves. Fixes gh#Mbed-TLS/mbedtls#8045.
Security
* Developers using mbedtls_pkcs5_pbes2() or mbedtls_pkcs12_pbe() should
review the size of the output buffer passed to this function, and note that
the output after decryption may include CBC padding. Consider moving to the
new functions mbedtls_pkcs5_pbes2_ext() or mbedtls_pkcs12_pbe_ext() which
checks for overflow of the output buffer and reports the actual length of
the output.
* Improve padding calculations in CBC decryption, NIST key unwrapping and
RSA OAEP decryption. With the previous implementation, some compilers
(notably recent versions of Clang and IAR) could produce non-constant time
code, which could allow a padding oracle attack if the attacker has access
to precise timing measurements.
* Fix a buffer overread when parsing short TLS application data records in
ARC4 or null-cipher cipher suites. Credit to OSS-Fuzz.
Bugfix
* Fix x509 certificate generation to conform to RFC 5480 / RFC 5758 when
using ECC key. The certificate was rejected by some crypto frameworks.
Fixes gh#Mbed-TLS/mbedtls#2924.
* Fix some cases where mbedtls_mpi_mod_exp, RSA key construction or ECDSA
signature can silently return an incorrect result in low memory conditions.
* Fix IAR compiler warnings. Fixes gh#Mbed-TLS/mbedtls#7873,
gh#Mbed-TLS/mbedtls#4300.
* Fix an issue when parsing an otherName subject alternative name into a
mbedtls_x509_san_other_name struct. The type-id of the otherName was not
copied to the struct. This meant that the struct had incomplete information
about the otherName SAN and contained uninitialized memory.
* Fix the detection of HardwareModuleName otherName SANs. These were being
detected by comparing the wrong field and the check was erroneously
inverted.
* Fix an error when MBEDTLS_ECDSA_SIGN_ALT is defined but not
MBEDTLS_ECDSA_VERIFY_ALT, causing ecdsa verify to fail. Fixes
gh#Mbed-TLS/mbedtls#7498. Functions in the ssl_cache module now return a
negative MBEDTLS_ERR_xxx error code on failure. Before, they returned 1 to
indicate failure in some cases involving a missing entry or a full cache.
Changes
* In configurations with ARIA or Camellia but not AES, the value of
MBEDTLS_CIPHER_BLKSIZE_MAX was 8, rather than 16 as the name might suggest.
This did not affect any library code, because this macro was only used in
relation with CMAC which does not support these ciphers. Its value is now
16 if ARIA or Camellia are present. This may affect application code that
uses this macro.
* Wed Aug 16 2023 Scott Bradnick <[email protected]>
- Update to 2.28.4:
Features
* Allow MBEDTLS_CONFIG_FILE and MBEDTLS_USER_CONFIG_FILE to be set by
setting the CMake variable of the same name at configuration time.
Bugfix
* Fix crypt_and_hash decryption fail when used with a stream cipher
mode of operation, due to the input not being a multiple of the block
size. Resolves #7417.
* Fix a bug where mbedtls_x509_string_to_names() would return success
when given a invalid name string, if it did not contain '=' or ','.
* Fix missing PSA initialization in sample programs when
MBEDTLS_USE_PSA_CRYPTO is enabled.
* Fix clang and armclang compilation error when targeting certain Arm
M-class CPUs (Cortex-M0, Cortex-M0+, Cortex-M1, Cortex-M23,
SecurCore SC000). Fixes #1077.
* Fixed an issue that caused compile errors when using CMake and the IAR
toolchain.
* Fix the build with MBEDTLS_PSA_INJECT_ENTROPY. Fixes #7516.
* Fix builds on Windows with clang.
* Fix compilation warnings in aes.c for certain combinations
of configuration options.
* Fix a compilation error on some platforms when including mbedtls/ssl.h
with all TLS support disabled. Fixes #6628.
Changes
* Update test data to avoid failures of unit tests after 2023-08-07, and
update expiring certififcates in the certs
* Mon May 08 2023 Jaime Marquínez Ferrándiz <[email protected]>
- Fix the use of the %{release} macro for the mbedtls-devel version
* Tue May 02 2023 Jaime Marquínez Ferrándiz <[email protected]>
- Update to 2.28.3:
Features
* Use HOSTCC (if it is set) when compiling C code during generation of the
configuration-independent files. This allows them to be generated when CC
is set for cross compilation.
* AES-NI is now supported with Visual Studio.
* AES-NI is now supported in 32-bit builds, or when MBEDTLS_HAVE_ASM is
disabled, when compiling with GCC or Clang or a compatible compiler for a
target CPU that supports the requisite instructions (for example gcc -m32
- msse2 -maes -mpclmul). (Generic x86 builds with GCC-like compilers still
require MBEDTLS_HAVE_ASM and a 64-bit target.)
Security
* MBEDTLS_AESNI_C, which is enabled by default, was silently ignored on
builds that couldn't compile the GCC-style assembly implementation (most
notably builds with Visual Studio), leaving them vulnerable to timing
side-channel attacks. There is now an intrinsics-based AES-NI
implementation as a fallback for when the assembly one cannot be used.
Bugfix
* Fix a build issue on Windows where the source and build directory could
not be on different drives (#5751).
* Fix possible integer overflow in mbedtls_timing_hardclock(), which
could cause a crash for certain platforms & compiler options.
* Fix IAR compiler warnings. Fixes #6924.
* Fix a bug in the build where directory names containing spaces were
causing generate_errors.pl to error out resulting in a build failure.
Fixes issue #6879.
* Fix compile error where MBEDTLS_RSA_C and MBEDTLS_X509_CRT_WRITE_C are
defined, but MBEDTLS_PK_RSA_ALT_SUPPORT is not defined. Fixes #3174.
* Fix a build issue when defining MBEDTLS_TIMING_ALT and MBEDTLS_SELF_TEST.
The library would not link if the user didn't provide an external self-test
function. The self-test is now provided regardless of the choice of
internal/alternative timing implementation. Fixes #6923.
* mbedtls_x509write_crt_set_serial() now explicitly rejects serial numbers
whose binary representation is longer than 20 bytes. This was already
forbidden by the standard (RFC5280 - section 4.1.2.2) and now it's being
enforced also at code level.
* Fix potential undefined behavior in mbedtls_mpi_sub_abs(). Reported by
Pascal Cuoq using TrustInSoft Analyzer in #6701; observed independently by
Aaron Ucko under Valgrind.
* Fix behavior of certain sample programs which could, when run with no
arguments, access uninitialized memory in some cases. Fixes #6700 (which
was found by TrustInSoft Analyzer during REDOCS'22) and #1120.
* Fix build errors in test programs when MBEDTLS_CERTS_C is disabled.
Fixes #6243.
* Fix parsing of X.509 SubjectAlternativeName extension. Previously,
malformed alternative name components were not caught during initial
certificate parsing, but only on subsequent calls to
mbedtls_x509_parse_subject_alt_name(). Fixes #2838.
* Fix bug in conversion from OID to string in
mbedtls_oid_get_numeric_string(). OIDs such as 2.40.0.25 are now printed
correctly.
* Reject OIDs with overlong-encoded subidentifiers when converting them to a
string.
* Reject OIDs with subidentifier values exceeding UINT_MAX. Such
subidentifiers can be valid, but Mbed TLS cannot currently handle them.
* Reject OIDs that have unterminated subidentifiers, or (equivalently) have
the most-significant bit set in their last byte.
* Silence a warning about an unused local variable in bignum.c on some
architectures. Fixes #7166.
* Silence warnings from clang -Wdocumentation about empty \retval
descriptions, which started appearing with Clang 15. Fixes #6960.
* Fix undefined behavior in mbedtls_ssl_read() and mbedtls_ssl_write() if
len argument is 0 and buffer is NULL.
Changes
* The C code follows a new coding style. This is transparent for users but
affects contributors and maintainers of local patches. For more
information, see
https://mbed-tls.readthedocs.io/en/latest/kb/how-to/rewrite-branch-for-coding-style/
* Changed the default MBEDTLS_ECP_WINDOW_SIZE from 6 to 2. As tested in
issue 6790, the correlation between this define and RSA decryption
performance has changed lately due to security fixes. To fix the
performance degradation when using default values the window was reduced
from 6 to 2, a value that gives the best or close to best results when
tested on Cortex-M4 and Intel i7.
* Mon May 01 2023 Jaime Marquínez Ferrándiz <[email protected]>
- Setup the mbedtls-2 package
* Wed Mar 08 2023 Martin Pluskal <[email protected]>
- Build AVX2 enabled hwcaps library for x86_64-v3
* Wed Dec 21 2022 Alexander Bergmann <[email protected]>
- Update to 2.28.2: (bsc#1206576, CVE-2022-46393)
Security:
* Fix potential heap buffer overread and overwrite in DTLS if
MBEDTLS_SSL_DTLS_CONNECTION_ID is enabled and
MBEDTLS_SSL_CID_IN_LEN_MAX > 2 * MBEDTLS_SSL_CID_OUT_LEN_MAX.
* An adversary with access to precise enough information about memory
accesses (typically, an untrusted operating system attacking a secure
enclave) could recover an RSA private key after observing the victim
performing a single private-key operation if the window size used for the
exponentiation was 3 or smaller. Found and reported by Zili KOU,
Wenjian HE, Sharad Sinha, and Wei ZHANG. See "Cache Side-channel Attacks
and Defenses of the Sliding Window Algorithm in TEEs" - Design, Automation
and Test in Europe 2023.
Bugfix:
* Fix a long-standing build failure when building x86 PIC code with old
gcc (4.x). The code will be slower, but will compile. We do however
recommend upgrading to a more recent compiler instead. Fixes #1910.
* Fix support for little-endian Microblaze when MBEDTLS_HAVE_ASM is defined.
Contributed by Kazuyuki Kimura to fix #2020.
* Use double quotes to include private header file psa_crypto_cipher.h.
Fixes 'file not found with include' error when building with Xcode.
* Fix handling of broken symlinks when loading certificates using
mbedtls_x509_crt_parse_path(). Instead of returning an error as soon as a
broken link is encountered, skip the broken link and continue parsing
other certificate files. Contributed by Eduardo Silva in #2602.
* Fix a compilation error when using CMake with an IAR toolchain.
Fixes #5964.
* Fix bugs and missing dependencies when building and testing
configurations with only one encryption type enabled in TLS 1.2.
* Provide the missing definition of mbedtls_setbuf() in some configurations
with MBEDTLS_PLATFORM_C disabled. Fixes #6118, #6196.
* Fix compilation errors when trying to build with
PSA drivers for AEAD (GCM, CCM, Chacha20-Poly1305).
* Fix memory leak in ssl_parse_certificate_request() caused by
mbedtls_x509_get_name() not freeing allocated objects in case of error.
Change mbedtls_x509_get_name() to clean up allocated objects on error.
* Fix checks on PK in check_config.h for builds with PSA and RSA. This does
not change which builds actually work, only moving a link-time error to
an early check.
* Fix ECDSA verification, where it was not always validating the
public key. This bug meant that it was possible to verify a
signature with an invalid public key, in some cases. Reported by
Guido Vranken using Cryptofuzz in #4420.
* Fix a possible null pointer dereference if a memory allocation fails
in TLS PRF code. Reported by Michael Madsen in #6516.
* Fix a bug in which mbedtls_x509_crt_info() would produce non-printable
bytes when parsing certificates containing a binary RFC 4108
HardwareModuleName as a Subject Alternative Name extension. Hardware
serial numbers are now rendered in hex format. Fixes #6262.
* Fix bug in error reporting in dh_genprime.c where upon failure,
the error code returned by mbedtls_mpi_write_file() is overwritten
and therefore not printed.
* In the bignum module, operations of the form (-A) - (+A) or (-A) - (-A)
with A > 0 created an unintended representation of the value 0 which was
not processed correctly by some bignum operations. Fix this. This had no
consequence on cryptography code, but might affect applications that call
bignum directly and use negative numbers.
* Fix undefined behavior (typically harmless in practice) of
mbedtls_mpi_add_mpi(), mbedtls_mpi_add_abs() and mbedtls_mpi_add_int()
when both operands are 0 and the left operand is represented with 0 limbs.
* Fix undefined behavior (typically harmless in practice) when some bignum
functions receive the most negative value of mbedtls_mpi_sint. Credit
to OSS-Fuzz. Fixes #6597.
* Fix undefined behavior (typically harmless in practice) in PSA ECB
encryption and decryption.
* Fri Nov 04 2022 Mia Herkt <[email protected]>
- Update to 2.28.1: (CVE-2022-35409)
Default behavior changes
* mbedtls_cipher_set_iv will now fail with ChaCha20 and
ChaCha20+Poly1305 for IV lengths other than 12. The library was
silently overwriting this length with 12, but did not inform
the caller about it.
gh#Mbed-TLS/mbedtls#4301
Features
* When MBEDTLS_PSA_CRYPTO_CONFIG is enabled, you may list the PSA
crypto feature requirements in the file named by the new macro
MBEDTLS_PSA_CRYPTO_CONFIG_FILE instead of the default
psa/crypto_config.h. Furthermore you may name an additional
file to include after the main file with the macro
MBEDTLS_PSA_CRYPTO_USER_CONFIG_FILE.
Security
* Zeroize dynamically-allocated buffers used by the PSA Crypto
key storage module before freeing them. These buffers contain
secret key material, and could thus potentially leak the key
through freed heap.
* Fix a potential heap buffer overread in TLS 1.2 server-side
when MBEDTLS_USE_PSA_CRYPTO is enabled, an opaque key (created
with mbedtls_pk_setup_opaque()) is provisioned, and a static
ECDH ciphersuite is selected. This may result in an application
crash or potentially an information leak.
* Fix a buffer overread in DTLS ClientHello parsing in servers
with MBEDTLS_SSL_DTLS_CLIENT_PORT_REUSE enabled.
An unauthenticated client or a man-in-the-middle could cause a
DTLS server to read up to 255 bytes after the end of the SSL
input buffer. The buffer overread only happens when
MBEDTLS_SSL_IN_CONTENT_LEN is less than a threshold that
depends on the exact configuration: 258 bytes if using
mbedtls_ssl_cookie_check(), and possibly up to 571 bytes with
a custom cookie check function.
Reported by the Cybeats PSI Team.
Bugfix
* Fix a memory leak if mbedtls_ssl_config_defaults() is called
twice.
* Fix several bugs (warnings, compiler and linker errors, test
failures) in reduced configurations when MBEDTLS_USE_PSA_CRYPTO
is enabled.
* Fix a bug in (D)TLS curve negotiation: when
MBEDTLS_USE_PSA_CRYPTO was enabled and an ECDHE-ECDSA or
ECDHE-RSA key exchange was used, the client would fail to check
that the curve selected by the server for ECDHE was indeed one
that was offered. As a result, the client would accept any
curve that it supported, even if that curve was not allowed
according to its configuration.
gh#Mbed-TLS/mbedtls#5291
* Fix unit tests that used 0 as the file UID. This failed on some
implementations of PSA ITS.
gh#Mbed-TLS/mbedtls#3838
* Fix API violation in mbedtls_md_process() test by adding a call
to mbedtls_md_starts().
gh#Mbed-TLS/mbedtls#2227
* Fix compile errors when MBEDTLS_HAVE_TIME is not defined.
Add tests to catch bad uses of time.h.
* Fix bug in the alert sending function
mbedtls_ssl_send_alert_message() potentially leading to
corrupted alert messages being sent in case the function needs
to be re-called after initially returning
MBEDTLS_SSL_WANT_WRITE.
gh#Mbed-TLS/mbedtls#1916
* In configurations with MBEDTLS_SSL_DTLS_CONNECTION_ID enabled
but none of MBEDTLS_SSL_HW_RECORD_ACCEL,
MBEDTLS_SSL_EXPORT_KEYS or MBEDTLS_DEBUG_C, DTLS handshakes
using CID would crash due to a null pointer dereference.
Fix this.
gh#Mbed-TLS/mbedtls#3998
* Fix incorrect documentation of mbedtls_x509_crt_profile. The
previous documentation stated that the allowed_pks field
applies to signatures only, but in fact it does apply to the
public key type of the end entity certificate, too.
gh#Mbed-TLS/mbedtls#1992
* Fix PSA cipher multipart operations using ARC4. Previously, an
IV was required but discarded. Now, an IV is rejected, as it
should be.
* Fix undefined behavior in mbedtls_asn1_find_named_data(), where
val is not NULL and val_len is zero. psa_raw_key_agreement()
now returns PSA_ERROR_BUFFER_TOO_SMALL when applicable.
gh#Mbed-TLS/mbedtls#5735
* Fix a bug in the x25519 example program where the removal of
MBEDTLS_ECDH_LEGACY_CONTEXT caused the program not to run.
gh#Mbed-TLS/mbedtls#4901
gh#Mbed-TLS/mbedtls#3191
* Encode X.509 dates before 1/1/2000 as UTCTime rather than
GeneralizedTime.
gh#Mbed-TLS/mbedtls#5465
* Fix order value of curve x448.
* Fix string representation of DNs when outputting values
containing commas and other special characters, conforming to
RFC 1779.
gh#Mbed-TLS/mbedtls#769
* Silence a warning from GCC 12 in the selftest program.
gh#Mbed-TLS/mbedtls#5974
* Fix mbedtls_asn1_write_mpi() writing an incorrect encoding of
0.
* Fix resource leaks in mbedtls_pk_parse_public_key() in low
memory conditions.
* Fix server connection identifier setting for outgoing encrypted
records on DTLS 1.2 session resumption. After DTLS 1.2 session
resumption with connection identifier, the Mbed TLS client now
properly sends the server connection identifier in encrypted
record headers.
gh#Mbed-TLS/mbedtls#5872
* Fix a null pointer dereference when performing some operations
on zero represented with 0 limbs (specifically
mbedtls_mpi_mod_int() dividing by 2, and
mbedtls_mpi_write_string() in base 2).
* Fix record sizes larger than 16384 being sometimes accepted
despite being non-compliant. This could not lead to a buffer
overflow. In particular, application data size was already
checked correctly.
* Mon Jan 17 2022 Guillaume GARDET <[email protected]>
- Fix baselib.conf
* Thu Jan 13 2022 Guillaume GARDET <[email protected]>
- Update to 2.28.0: (bsc#1193979, CVE-2021-45450)
API changes
* Some fields of mbedtls_ssl_session and mbedtls_ssl_config are in a
different order. This only affects applications that define such
structures directly or serialize them.
Requirement changes
* Sign-magnitude and one's complement representations for signed integers are
not supported. Two's complement is the only supported representation.
Removals
* Remove config option MBEDTLS_TLS_DEFAULT_ALLOW_SHA1_IN_CERTIFICATES,
which allowed SHA-1 in the default TLS configuration for certificate
signing. It was intended to facilitate the transition in environments
with SHA-1 certificates. SHA-1 is considered a weak message digest and
its use constitutes a security risk.
* Remove the partial support for running unit tests via Greentea on Mbed OS,
which had been unmaintained since 2018.
Features
* The identifier of the CID TLS extension can be configured by defining
MBEDTLS_TLS_EXT_CID at compile time.
* Warn if errors from certain functions are ignored. This is currently
supported on GCC-like compilers and on MSVC and can be configured through
the macro MBEDTLS_CHECK_RETURN. The warnings are always enabled
(where supported) for critical functions where ignoring the return
value is almost always a bug. Enable the new configuration option
MBEDTLS_CHECK_RETURN_WARNING to get warnings for other functions. This
is currently implemented in the AES, DES and md modules, and will be
extended to other modules in the future.
* Add missing PSA macros declared by PSA Crypto API 1.0.0:
PSA_ALG_IS_SIGN_HASH, PSA_ALG_NONE, PSA_HASH_BLOCK_LENGTH, PSA_KEY_ID_NULL.
* Add new API mbedtls_ct_memcmp for constant time buffer comparison.
* Add PSA API definition for ARIA.
Security
* Zeroize several intermediate variables used to calculate the expected
value when verifying a MAC or AEAD tag. This hardens the library in
case the value leaks through a memory disclosure vulnerability. For
example, a memory disclosure vulnerability could have allowed a
man-in-the-middle to inject fake ciphertext into a DTLS connection.
* In psa_cipher_generate_iv() and psa_cipher_encrypt(), do not read back
from the output buffer. This fixes a potential policy bypass or decryption
oracle vulnerability if the output buffer is in memory that is shared with
an untrusted application.
* Fix a double-free that happened after mbedtls_ssl_set_session() or
mbedtls_ssl_get_session() failed with MBEDTLS_ERR_SSL_ALLOC_FAILED
(out of memory). After that, calling mbedtls_ssl_session_free()
and mbedtls_ssl_free() would cause an internal session buffer to
be free()'d twice.
Bugfix
* Stop using reserved identifiers as local variables. Fixes #4630.
* The GNU makefiles invoke python3 in preference to python except on Windows.
* The check was accidentally not performed when cross-compiling for Windows
on Linux. Fix this. Fixes #4774.
* Prevent divide by zero if either of PSA_CIPHER_ENCRYPT_OUTPUT_SIZE() or
PSA_CIPHER_UPDATE_OUTPUT_SIZE() were called using an asymmetric key type.
* Fix a parameter set but unused in psa_crypto_cipher.c. Fixes #4935.
* Don't use the obsolete header path sys/fcntl.h in unit tests.
These header files cause compilation errors in musl.
Fixes #4969.
* Fix missing constraints on x86_64 and aarch64 assembly code
for bignum multiplication that broke some bignum operations with
(at least) Clang 12.
Fixes #4116, #4786, #4917, #4962.
* Fix mbedtls_cipher_crypt: AES-ECB when MBEDTLS_USE_PSA_CRYPTO is enabled.
* Failures of alternative implementations of AES or DES single-block
functions enabled with MBEDTLS_AES_ENCRYPT_ALT, MBEDTLS_AES_DECRYPT_ALT,
MBEDTLS_DES_CRYPT_ECB_ALT or MBEDTLS_DES3_CRYPT_ECB_ALT were ignored.
This does not concern the implementation provided with Mbed TLS,
where this function cannot fail, or full-module replacements with
MBEDTLS_AES_ALT or MBEDTLS_DES_ALT. Reported by Armelle Duboc in #1092.
* Some failures of HMAC operations were ignored. These failures could only
happen with an alternative implementation of the underlying hash module.
* Fix the error returned by psa_generate_key() for a public key. Fixes #4551.
* Fix the build of sample programs when neither MBEDTLS_ERROR_C nor
MBEDTLS_ERROR_STRERROR_DUMMY is enabled.
* Fix PSA_ALG_RSA_PSS verification accepting an arbitrary salt length.
This algorithm now accepts only the same salt length for verification
that it produces when signing, as documented. Use the new algorithm
PSA_ALG_RSA_PSS_ANY_SALT to accept any salt length. Fixes #4946.
* The existing predicate macro name PSA_ALG_IS_HASH_AND_SIGN is now reserved
for algorithm values that fully encode the hashing step, as per the PSA
Crypto API specification. This excludes PSA_ALG_RSA_PKCS1V15_SIGN_RAW and
PSA_ALG_ECDSA_ANY. The new predicate macro PSA_ALG_IS_SIGN_HASH covers
all algorithms that can be used with psa_{sign,verify}_hash(), including
these two.
* Fix issue in Makefile on Linux with SHARED=1, that caused shared libraries
not to list other shared libraries they need.
* Fix a bug in mbedtls_gcm_starts() when the bit length of the iv
exceeds 2^32. Fixes #4884.
* Fix an uninitialized variable warning in test_suite_ssl.function with GCC
version 11.
* Fix the build when no SHA2 module is included. Fixes #4930.
* Fix the build when only the bignum module is included. Fixes #4929.
* Fix a potential invalid pointer dereference and infinite loop bugs in
pkcs12 functions when the password is empty. Fix the documentation to
better describe the inputs to these functions and their possible values.
Fixes #5136.
* The key usage flags PSA_KEY_USAGE_SIGN_MESSAGE now allows the MAC
operations psa_mac_compute() and psa_mac_sign_setup().
* The key usage flags PSA_KEY_USAGE_VERIFY_MESSAGE now allows the MAC
operations psa_mac_verify() and psa_mac_verify_setup().
Changes
* Set config option MBEDTLS_TLS_DEFAULT_ALLOW_SHA1_IN_KEY_EXCHANGE to be
disabled by default.
* Improve the performance of base64 constant-flow code. The result is still
slower than the original non-constant-flow implementation, but much faster
than the previous constant-flow implementation. Fixes #4814.
* Indicate in the error returned if the nonce length used with
ChaCha20-Poly1305 is invalid, and not just unsupported.
* The mbedcrypto library includes a new source code module constant_time.c,
containing various functions meant to resist timing side channel attacks.
* This module does not have a separate configuration option, and functions
from this module will be included in the build as required. Currently
most of the interface of this module is private and may change at any
time.
* Tue Jul 20 2021 Pedro Monreal <[email protected]>
- Update to 2.27.0:
API changes:
* Update AEAD output size macros to bring them in line with the PSA Crypto
API version 1.0 spec. This version of the spec parameterizes them on the
key type used, as well as the key bit-size in the case of
PSA_AEAD_TAG_LENGTH.
The old versions of these macros were renamed and deprecated as follows:
- PSA_AEAD_TAG_LENGTH -> PSA_AEAD_TAG_LENGTH_1_ARG
- PSA_AEAD_ENCRYPT_OUTPUT_SIZE -> PSA_AEAD_ENCRYPT_OUTPUT_SIZE_2_ARG
- PSA_AEAD_DECRYPT_OUTPUT_SIZE -> PSA_AEAD_DECRYPT_OUTPUT_SIZE_2_ARG
- PSA_AEAD_UPDATE_OUTPUT_SIZE -> PSA_AEAD_UPDATE_OUTPUT_SIZE_2_ARG
- PSA_AEAD_FINISH_OUTPUT_SIZE -> PSA_AEAD_FINISH_OUTPUT_SIZE_1_ARG
- PSA_AEAD_VERIFY_OUTPUT_SIZE -> PSA_AEAD_VERIFY_OUTPUT_SIZE_1_ARG
* Implement one-shot cipher functions, psa_cipher_encrypt and
psa_cipher_decrypt, according to the PSA Crypto API 1.0.0
specification.
Features:
* Add mbedtls_rsa_rsassa_pss_sign_ext() function allowing to generate a
signature with a specific salt length. This function allows to validate
test cases provided in the NIST's CAVP test suite.
* Added support for built-in driver keys through the PSA opaque crypto
driver interface. Refer to the documentation of
MBEDTLS_PSA_CRYPTO_BUILTIN_KEYS for more information.
* Implement psa_sign_message() and psa_verify_message().
* The new function mbedtls_mpi_random() generates a random value in a
given range uniformly.
* Implement psa_mac_compute() and psa_mac_verify() as defined in the
PSA Cryptograpy API 1.0.0 specification.
* MBEDTLS_ECP_MAX_BITS is now determined automatically from the configured
curves and no longer needs to be configured explicitly to save RAM.
Security
* Fix a bias in the generation of finite-field Diffie-Hellman-Merkle (DHM)
private keys and of blinding values for DHM and elliptic curves (ECP)
computations.
* Fix a potential side channel vulnerability in ECDSA ephemeral key generation.
An adversary who is capable of very precise timing measurements could
learn partial information about the leading bits of the nonce used for the
signature, allowing the recovery of the private key after observing a
large number of signature operations. This completes a partial fix in
Mbed TLS 2.20.0.
* It was possible to configure MBEDTLS_ECP_MAX_BITS to a value that is
too small, leading to buffer overflows in ECC operations. Fail the build
in such a case.
* An adversary with access to precise enough information about memory
accesses (typically, an untrusted operating system attacking a secure
enclave) could recover an RSA private key after observing the victim
performing a single private-key operation.
* An adversary with access to precise enough timing information (typically, a
co-located process) could recover a Curve25519 or Curve448 static ECDH key
after inputting a chosen public key and observing the victim performing the
corresponding private-key operation.
Bugfix
* Add printf function attributes to mbedtls_debug_print_msg to ensure we
get printf format specifier warnings.
* Fix premature fopen() call in mbedtls_entropy_write_seed_file which may
lead to seed file corruption in the case where the path to the seed file is
equal to MBEDTLS_PLATFORM_STD_NV_SEED_FILE.
* PSA functions other than psa_open_key now return PSA_ERROR_INVALID_HANDLE
rather than PSA_ERROR_DOES_NOT_EXIST for an invalid handle, bringing them
in line with version 1.0.0 of the specification.
* PSA functions creating a key now return PSA_ERROR_INVALID_ARGUMENT rather
than PSA_ERROR_INVALID_HANDLE when the identifier specified for the key
to create is not valid, bringing them in line with version 1.0.0 of the
specification.
* Fix some cases in the bignum module where the library constructed an
unintended representation of the value 0 which was not processed
correctly by some bignum operations. This could happen when
mbedtls_mpi_read_string() was called on "-0", or when
mbedtls_mpi_mul_mpi() and mbedtls_mpi_mul_int() was called with one of
the arguments being negative and the other being 0.
* Fix a bug in ECDSA that would cause it to fail when the hash is all-bits
zero.
* Fix a compilation error when MBEDTLS_ECP_RANDOMIZE_MXZ_ALT is
defined.
* Fix an incorrect error code when parsing a PKCS#8 private key.
* In a TLS client, enforce the Diffie-Hellman minimum parameter size
set with mbedtls_ssl_conf_dhm_min_bitlen() precisely. Before, the
minimum size was rounded down to the nearest multiple of 8.
* In library/net_sockets.c, _POSIX_C_SOURCE and _XOPEN_SOURCE are
defined to specific values. If the code is used in a context
where these are already defined, this can result in a compilation
error. Instead, assume that if they are defined, the values will
be adequate to build Mbed TLS.
* The cipher suite TLS-RSA-WITH-CAMELLIA-256-GCM-SHA384 was not available
when SHA-1 was disabled and was offered when SHA-1 was enabled but SHA-384
was disabled. Fix the dependency.
* Do not offer SHA384 cipher suites when SHA-384 is disabled.
* With MBEDTLS_PSA_CRYPTO_C disabled, some functions were getting built
nonetheless, resulting in undefined reference errors when building a
shared library.
* Fix test suite code on platforms where int32_t is not int, such as
Arm Cortex-M.
* Fix some issues affecting MBEDTLS_ARIA_ALT implementations: a misplaced
directive in a header and a missing initialization in the self-test.
* Fix a missing initialization in the Camellia self-test, affecting
MBEDTLS_CAMELLIA_ALT implementations.
* Restore the ability to configure PSA via Mbed TLS options to support RSA
key pair operations but exclude RSA key generation. When MBEDTLS_GENPRIME
is not defined PSA will no longer attempt to use mbedtls_rsa_gen_key().
* Fix a regression introduced in 2.24.0 which broke (D)TLS CBC ciphersuites
(when the encrypt-then-MAC extension is not in use) with some ALT
implementations of the underlying hash (SHA-1, SHA-256, SHA-384), causing
the affected side to wrongly reject valid messages.
* Remove outdated check-config.h check that prevented implementing the
timing module on Mbed OS.
* Fix PSA_ALG_TLS12_PRF and PSA_ALG_TLS12_PSK_TO_MS being too permissive
about missing inputs.
* Fix a resource leak in a test suite with an alternative AES
implementation.
* Fix a crash in mbedtls_mpi_debug_mpi on a bignum having 0 limbs. This
could notably be triggered by setting the TLS debug level to 3 or above
and using a Montgomery curve for the key exchange.
* psa_verify_hash() was relying on implementation-specific behavior of
mbedtls_rsa_rsassa_pss_verify() and was causing failures in some _ALT
implementations. This reliance is now removed.
* Disallow inputs of length different from the corresponding hash when
signing or verifying with PSA_ALG_RSA_PSS (The PSA Crypto API mandates
that PSA_ALG_RSA_PSS uses the same hash throughout the algorithm.)
* Fix a null pointer dereference when mbedtls_mpi_exp_mod() was called with
A=0 represented with 0 limbs. Up to and including Mbed TLS 2.26, this bug
could not be triggered by code that constructed A with one of the
mbedtls_mpi_read_xxx functions (including in particular TLS code) since
those always built an mpi object with at least one limb.
* Fix mbedtls_mpi_gcd(G,A,B) when the value of B is zero. This had no
effect on Mbed TLS's internal use of mbedtls_mpi_gcd(), but may affect
applications that call mbedtls_mpi_gcd() directly.
* The PSA API no longer allows the creation or destruction of keys with a
read-only lifetime. The persistence level PSA_KEY_PERSISTENCE_READ_ONLY
can now only be used as intended, for keys that cannot be modified through
normal use of the API.
* When MBEDTLS_PSA_CRYPTO_SPM is enabled, crypto_spe.h was not included
in all the right places. Include it from crypto_platform.h, which is
the natural place.
* mbedtls_pk_sign() and mbedtls_pk_verify() and their extended and
restartable variants now always honor the specified hash length if
nonzero. Before, for RSA, hash_len was ignored in favor of the length of
the specified hash algorithm.
* Fix which alert is sent in some cases to conform to the
applicable RFC: on an invalid Finished message value, an
invalid max_fragment_length extension, or an
unsupported extension used by the server.
* Correct (change from 12 to 13 bytes) the value of the macro describing the
maximum nonce length returned by psa_aead_generate_nonce().
Changes
* Add extra printf compiler warning flags to builds.
* Fix memsan build false positive in x509_crt.c with Clang 11
* Fix the setting of the read timeout in the DTLS sample programs.
* Remove the AES sample application programs/aes/aescrypt2 which shows
bad cryptographic practice.
* Alternative implementations of CMAC may now opt to not support 3DES as a
CMAC block cipher, and still pass the CMAC self test.
* Remove configs/config-psa-crypto.h, which was identical to the default
configuration except for having some extra cryptographic mechanisms
enabled and for unintended differences. This configuration was primarily
intended to demonstrate the PSA API, and lost most of its usefulness when
MBEDTLS_PSA_CRYPTO_C became enabled by default.
* When building the test suites with GNU make, invoke python3 or python, not
python2, which is no longer supported upstream.
* When using session cache based session resumption on the server,
double-check that custom session cache implementations return
sessions which are consistent with the negotiated ciphersuite
and compression method.
* Fix build failure on MinGW toolchain when __USE_MING_ANSI_STDIO is on.
When that flag is on, standard GNU C printf format specifiers
should be used.
* Reduce the default value of MBEDTLS_ECP_WINDOW_SIZE. This reduces RAM usage
during ECC operations at a negligible performance cost.
* mbedtls_mpi_read_binary(), mbedtls_mpi_read_binary_le() and
mbedtls_mpi_read_string() now construct an mbedtls_mpi object with 0 limbs
when their input has length 0. Note that this is an implementation detail
and can change at any time, so this change should be transparent, but it
may result in mbedtls_mpi_write_binary() or mbedtls_mpi_write_string()
now writing an empty string where it previously wrote one or more
zero digits when operating from values constructed with an mpi_read
function and some mpi operations.
* Implicitly add PSA_KEY_USAGE_SIGN_MESSAGE key usage policy flag when
PSA_KEY_USAGE_SIGN_HASH flag is set and PSA_KEY_USAGE_VERIFY_MESSAGE flag
when PSA_KEY_USAGE_VERIFY_HASH flag is set. This usage flag extension
is also applied when loading a key from storage.
