| Summary: A SIMD-accelerated library for manipulating JPEG image files | |
The libjpeg-turbo package contains a library of functions for manipulating JPEG images. It supports architecture-specific SIMD instructions, such as SSE/SSE2/AVX2, AltiVec, NEON, MIPS DSPR2, and Loongson MMI. It also includes the following command line utilities: djpeg - decompress a JPEG file to an image file jpegtran - lossless transformation of JPEG files rdjpgcom - display text comments from a JPEG file wrjpgcom - insert text comments into a JPEG file tjbench - a JPEG decompression/compression benchmark

- update to 3.0.4:
* Fixed an issue whereby the CPU usage of the default marker
processor in the decompressor grew exponentially with the
number of markers. This caused an unreasonable slow-down in
`jpeg_read_header()` if an application called `jpeg_save_markers()`
to save markers of a particular type and then attempted to
decompress a JPEG image containing an excessive number of markers
of that type.
* Hardened the default marker processor in the decompressor to guard
against an issue (exposed by 3.0 beta2[6]) whereby attempting to
decompress a specially-crafted malformed JPEG image (specifically
an image with a complete 12-bit-per-sample Start Of Frame segment
followed by an incomplete 8-bit-per-sample Start Of Frame segment)
using buffered-image mode and input prefetching caused a segfault
if the `fill_input_buffer()` method in the calling application's
custom source manager incorrectly returned `FALSE` in response to a
prematurely-terminated JPEG data stream.
* Fixed an issue in cjpeg whereby, when generating a
12-bit-per-sample or 16-bit-per-sample lossless JPEG image,
specifying a point transform value greater than 7 resulted in an
error ("Invalid progressive/lossless parameters") unless the
`-precision` option was specified before the `-lossless` option.
* Fixed a regression introduced by 3.0.3[3] that made it impossible
for calling applications to generate 12-bit-per-sample
arithmetic-coded lossy JPEG images using the TurboJPEG API.
* Fixed an error ("Destination buffer is not large enough") that
occurred when attempting to generate a full-color lossless JPEG
image using the TurboJPEG Java API's `byte[]
TJCompressor.compress()` method if the value of `TJ.PARAM_SUBSAMP`
was not `TJ.SAMP_444`.
* Fixed a segfault in djpeg that occurred if a negative width was
specified with the `-crop` option. Since the cropping region width
was read into an unsigned 32-bit integer, a negative width was
interpreted as a very large value. With certain negative width and
positive left boundary values, the bounds checks in djpeg and
`jpeg_crop_scanline()` overflowed and did not detect the
out-of-bounds width, which caused a buffer overrun in the
upsampling or color conversion routine. Both bounds checks now use
64-bit integers to guard against overflow, and djpeg now checks for
negative numbers when it parses the crop specification from the
command line.
* Fixed an issue whereby the TurboJPEG lossless transformation
function and methods checked the specified cropping region against
the source image dimensions and level of chrominance subsampling
rather than the destination image dimensions and level of
chrominance subsampling, which caused some cropping regions to be
unduly rejected when performing 90-degree rotation, 270-degree
rotation, transposition, transverse transposition, or grayscale
conversion.
* Fixed an issue whereby the TurboJPEG lossless transformation
function and methods did not honor
`TJXOPT_COPYNONE`/`TJTransform.OPT_COPYNONE` unless it was
specified for all lossless transforms.
* Sat Aug 31 2024 Dirk Müller <[email protected]>
- update to 3.0.3:
* The x86-64 SIMD extensions now include support for Intel
Control-flow Enforcement Technology (CET), which is enabled
automatically if CET is enabled in the C compiler.
* Fixed a regression introduced by 3.0 beta2[6] that made it
impossible for calling applications to supply custom Huffman
tables when generating 12-bit-per-component lossy JPEG images
using the libjpeg API.
* Fixed a segfault that occurred when attempting to use the
jpegtran `-drop` option with a specially-crafted malformed
input image or drop image (specifically an image in which all
of the scans contain fewer components than the number of
components specified in the Start Of Frame segment.)
* Mon Feb 05 2024 Martin Hauke <[email protected]>
- Update to version 3.0.2
* Fixed a signed integer overflow in the tj3CompressFromYUV8(),
tj3DecodeYUV8(), tj3DecompressToYUV8(), and tj3EncodeYUV8()
functions, detected by the Clang and GCC undefined behavior
sanitizers, that could be triggered by setting the align
parameter to an unreasonably large value. This issue did not
pose a security threat, but removing the warning made it
easier to detect actual security issues, should they arise in
the future.
* Introduced a new parameter (TJPARAM_MAXMEMORY in the
TurboJPEG C API and TJ.PARAM_MAXMEMORY in the TurboJPEG Java
API) and a corresponding TJBench option (-maxmemory) for
specifying the maximum amount of memory (in megabytes) that
will be allocated for intermediate buffers, which are used
with progressive JPEG compression and decompression, optimized
baseline entropy coding, lossless JPEG compression, and
lossless transformation. The new parameter and option serve
the same purpose as the max_memory_to_use field in the
jpeg_memory_mgr struct in the libjpeg API, the JPEGMEM
environment variable, and the cjpeg/djpeg/jpegtran -maxmemory
option.
* Introduced a new parameter (TJPARAM_MAXPIXELS in the TurboJPEG
C API and TJ.PARAM_MAXPIXELS in the TurboJPEG Java API) and a
corresponding TJBench option (-maxpixels) for specifying the
maximum number of pixels that the decompression, lossless
transformation, and packed-pixel image loading
functions/methods will process.
* Fixed an error ("Unsupported color conversion request") that
occurred when attempting to decompress a 3-component lossless
JPEG image without an Adobe APP14 marker. The decompressor
now assumes that a 3-component lossless JPEG image without an
Adobe APP14 marker uses the RGB colorspace if its component
IDs are 1, 2, and 3.

- Do not require SIMD support when it does not exist
* Mon Jan 01 2024 Dirk Müller <[email protected]>
- update to 3.0.1 (bsc#1211542, CVE-2023-2804):
* The x86-64 SIMD functions now use a standard stack frame,
prologue, and epilogue so that debuggers and profilers can
reliably capture backtraces from within the functions.
* Fixed two minor issues in the interblock smoothing algorithm
that caused mathematical (but not necessarily perceptible)
edge block errors when decompressing progressive JPEG images
exactly two MCU blocks in width or that use vertical
chrominance subsampling.
* The TurboJPEG API now supports 4:4:1 (transposed 4:1:1)
chrominance subsampling, which allows losslessly transposed or
rotated 4:1:1 JPEG images to be losslessly cropped, partially
decompressed, or decompressed to planar YUV images.
* Fixed various segfaults and buffer overruns (CVE-2023-2804)
* that occurred when attempting to decompress various
specially-crafted malformed 12-bit-per-component and
16-bit-per-component lossless JPEG images using color
quantization or merged chroma upsampling/color conversion. The
underlying cause of these issues was that the color
quantization and merged chroma upsampling/color conversion
algorithms were not designed with lossless decompression
in mind. Since libjpeg-turbo explicitly does not support color
conversion when compressing or decompressing lossless JPEG
images, merged chroma upsampling/color conversion never should
have been enabled for such images. Color quantization is a
legacy feature that serves little or no purpose with lossless
JPEG images, so it is also now disabled when decompressing such
images. (As a result, djpeg can no longer decompress a
lossless JPEG image into a GIF image.)
* Fixed an oversight in 1.4 beta1[8] that caused various
segfaults and buffer overruns when attempting to decompress
various specially-crafted malformed 12-bit-per-component JPEG
images using djpeg with both color quantization and RGB565
color conversion enabled.
* Fixed an issue whereby `jpeg_crop_scanline()` sometimes
miscalculated the downsampled width for components with 4x2 or
2x4 subsampling factors if decompression scaling was enabled.
This caused the components to be upsampled incompletely, which
caused the color converter to read from uninitialized memory.
With 12-bit data precision, this caused a buffer overrun or
underrun and subsequent segfault if the sample value read from
uninitialized memory was outside of the valid sample range.
* Fixed a long-standing issue whereby the `tj3Transform()`
function, when used with the `TJXOP_TRANSPOSE`,
`TJXOP_TRANSVERSE`, `TJXOP_ROT90`, or `TJXOP_ROT270` transform
operation and without automatic JPEG destination buffer
(re)allocation or lossless cropping, computed the worst-case
transformed JPEG image size based on the source image
dimensions rather than the transformed image dimensions. If a
calling program allocated the JPEG destination buffer based on
the transformed image dimensions, as the API documentation
instructs, and attempted to transform a specially-crafted
4:2:2, 4:4:0, 4:1:1, or 4:4:1 JPEG source image containing a
large amount of metadata, the issue caused `tj3Transform()` to
overflow the JPEG destination buffer rather than fail
gracefully. The issue could be worked around by setting
`TJXOPT_COPYNONE`. Note that, irrespective of this issue,
`tj3Transform()` cannot reliably transform JPEG source images
that contain a large amount of metadata unless automatic JPEG
destination buffer (re)allocation is used or `TJXOPT_COPYNONE`
is set.
* Significantly sped up the computation of optimal Huffman
tables. This speeds up the compression of tiny images by as
much as 2x and provides a noticeable speedup for images as
large as 256x256 when using optimal Huffman tables.
* All deprecated fields, constructors, and methods in the
TurboJPEG Java API have been removed.
* Arithmetic entropy coding is now supported with
12-bit-per-component JPEG images.
* Overhauled the TurboJPEG API to address long-standing
limitations and to make the API more extensible and intuitive.

- update to 2.1.5.1:
* Fixed a regression introduced by 2.0 beta1[15] that caused a buffer
overrun in the progressive Huffman encoder when attempting to transform
a specially-crafted malformed 12-bit-per-component JPEG image into a
progressive 12-bit-per-component JPEG image using a 12-bit-per-component
build of libjpeg-turbo.
* Fixed an issue whereby, when using a 12-bit-per-component build of
libjpeg-turbo (-DWITH_12BIT=1), passing samples with values greater than 4095
or less than 0 to jpeg_write_scanlines() caused a buffer overrun or
underrun in the RGB-to-YCbCr color converter.
* Fixed a floating point exception that occurred when attempting to use
the jpegtran -drop and -trim options to losslessly transform a
specially-crafted malformed JPEG image.
* Fixed an issue in tjBufSizeYUV2() whereby it returned a bogus result,
rather than throwing an error, if the align parameter was not a power of 2.
* Fixed a similar issue in tjCompressFromYUV() whereby it generated a corrupt
JPEG image in certain cases, rather than throwing an error,
if the align parameter was not a power of 2.
* Fixed an issue whereby tjDecompressToYUV2(), which is a wrapper for
tjDecompressToYUVPlanes(), used the desired YUV image dimensions
rather than the actual scaled image dimensions when computing the plane
pointers and strides to pass to tjDecompressToYUVPlanes().
This caused a buffer overrun and subsequent segfault if the desired
image dimensions exceeded the scaled image dimensions.
* Fixed an issue whereby, when decompressing a 12-bit-per-component JPEG
image (-DWITH_12BIT=1) using an alpha-enabled output color space such as
JCS_EXT_RGBA, the alpha channel was set to 255 rather than 4095.
* Fixed an issue whereby the Java version of TJBench did not accept a range
of quality values.
* Fixed an issue whereby, when -progressive was passed to TJBench,
the JPEG input image was not transformed into a progressive JPEG image
prior to decompression.

- Add explicit provides for jpegtran, so it can be installed easier
* Wed Aug 17 2022 Dirk Müller <[email protected]>
- update to 2.1.4:
* The `tjDecompressHeader3()` function in the TurboJPEG C API and the
`TJDecompressor.setSourceImage()` method in the TurboJPEG Java API now accept
"abbreviated table specification" (AKA "tables-only") datastreams, which can be
used to prime the decompressor with quantization and Huffman tables that can be
used when decompressing subsequent "abbreviated image" datastreams.
* libjpeg-turbo now performs run-time detection of AltiVec instructions on
OS X/PowerPC systems if AltiVec instructions are not enabled at compile time.
This allows both AltiVec-equipped (PowerPC G4 and G5) and non-AltiVec-equipped
(PowerPC G3) CPUs to be supported using the same build of libjpeg-turbo.
* Fixed an error ("Bogus virtual array access") that occurred when attempting
to decompress a progressive JPEG image with a height less than or equal to one
iMCU (8 * the vertical sampling factor) using buffered-image mode with
interblock smoothing enabled.
* Fixed two issues that prevented partial image decompression from working
properly with buffered-image mode:
- Attempting to call `jpeg_crop_scanline()` after
`jpeg_start_decompress()` but before `jpeg_start_output()` resulted in an error
("Improper call to JPEG library in state 207".)
- Attempting to use `jpeg_skip_scanlines()` resulted in an error ("Bogus
virtual array access") under certain circumstances.
* Mon Aug 15 2022 Tom Mbrt <[email protected]>
- update to 2.1.4:
* Fixed a regression introduced in 2.1.3 that caused build failures with
Visual Studio 2010.
* The tjDecompressHeader3() function in the TurboJPEG C API and the
TJDecompressor.setSourceImage() method in the TurboJPEG Java API now
accept "abbreviated table specification" (AKA "tables-only") datastreams,
which can be used to prime the decompressor with quantization and Huffman
tables that can be used when decompressing subsequent "abbreviated image"
datastreams.
* libjpeg-turbo now performs run-time detection of AltiVec instructions on
OS X/PowerPC systems if AltiVec instructions are not enabled at compile
time. This allows both AltiVec-equipped (PowerPC G4 and G5) and
non-AltiVec-equipped (PowerPC G3) CPUs to be supported using the same
build of libjpeg-turbo.
* Fixed an error ("Bogus virtual array access") that occurred when
attempting to decompress a progressive JPEG image with a height less than
or equal to one iMCU (8 * the vertical sampling factor) using
buffered-image mode with interblock smoothing enabled. This was a
regression introduced by 2.1 beta1[6(b)].
* Fixed two issues that prevented partial image decompression from working
properly with buffered-image mode:
* Attempting to call jpeg_crop_scanline() after jpeg_start_decompress()
but before jpeg_start_output() resulted in an error ("Improper call to
JPEG library in state 207".)
* Attempting to use jpeg_skip_scanlines() resulted in an error ("Bogus
virtual array access") under certain circumstances.

* Sun Mar 20 2022 Dirk Müller <[email protected]>
- update to 2.1.3:
* Fixed a regression introduced by 2.0 beta1[7] whereby cjpeg compressed PGM
input files into full-color JPEG images unless the `-grayscale` option was
used.
* cjpeg now automatically compresses GIF and 8-bit BMP input files into
grayscale JPEG images if the input files contain only shades of gray.
* The build system now enables the intrinsics implementation of the AArch64
(Arm 64-bit) Neon SIMD extensions by default when using GCC 12 or later.
* Fixed a segfault that occurred while decompressing a 4:2:0 JPEG image using
the merged (non-fancy) upsampling algorithms (that is, with
`cinfo.do_fancy_upsampling` set to `FALSE`) along with `jpeg_crop_scanline()`.
Specifically, the segfault occurred if the number of bytes remaining in the
output buffer was less than the number of bytes required to represent one
uncropped scanline of the output image. For that reason, the issue could only
be reproduced using the libjpeg API, not using djpeg.
* Wed Nov 24 2021 Dirk Müller <[email protected]>
- update to 2.1.2:
* Fixed a regression introduced by 2.1 beta1[13] that caused the remaining
GAS implementations of AArch64 (Arm 64-bit) Neon SIMD functions (which are used
by default with GCC for performance reasons) to be placed in the `.rodata`
section rather than in the `.text` section. This caused the GNU linker to
automatically place the `.rodata` section in an executable segment, which
prevented libjpeg-turbo from working properly with other linkers and also
represented a potential security risk.
* Fixed an issue whereby the `tjTransform()` function incorrectly computed the
MCU block size for 4:4:4 JPEG images with non-unary sampling factors and thus
unduly rejected some cropping regions, even though those regions aligned with
8x8 MCU block boundaries.
* Fixed a regression introduced by 2.1 beta1[13] that caused the build system
to enable the Arm Neon SIMD extensions when targetting Armv6 and other legacy
architectures that do not support Neon instructions.
* libjpeg-turbo now performs run-time detection of AltiVec instructions on
FreeBSD/PowerPC systems if AltiVec instructions are not enabled at compile
time. This allows both AltiVec-equipped and non-AltiVec-equipped CPUs to be
supported using the same build of libjpeg-turbo.
* cjpeg now accepts a `-strict` argument similar to that of djpeg and
jpegtran, which causes the compressor to abort if an LZW-compressed GIF input
image contains incomplete or corrupt image data.

- version update to 2.1.1
1. Fixed a regression introduced in 2.1.0 that caused build failures
with non-GCC-compatible compilers for Un*x/Arm platforms.
2. Fixed a regression introduced by 2.1 beta1[13] that prevented the
Arm 32-bit (AArch32) Neon SIMD extensions from building unless
the C compiler flags included -mfloat-abi=softfp or -mfloat-abi=hard.
3. Fixed an issue in the AArch32 Neon SIMD Huffman encoder whereby
reliance on undefined C compiler behavior led to crashes
("SIGBUS: illegal alignment") on Android systems when running
AArch32/Thumb builds of libjpeg-turbo built with recent versions
of Clang.
4. Added a command-line argument (-copy icc) to jpegtran that causes
it to copy only the ICC profile markers from the source file and
discard any other metadata.
5. libjpeg-turbo should now build and run on CHERI-enabled
architectures, which use capability pointers that are larger than
the size of size_t.
6. Fixed a regression introduced by 2.1 beta1[5] that caused a segfault
in the 64-bit SSE2 Huffman encoder when attempting to losslessly
transform a specially-crafted malformed JPEG image.
