- 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

- 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

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.)

=====
* The x86-64 SIMD functions now use a standard stack frame, prologue, and

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.
* Fixed a regression introduced by 3.0 beta2[6] that, in rare cases, caused
the C Huffman encoder (which is not used by default on x86 and Arm CPUs) to
generate incorrect results if the Neon SIMD extensions were explicitly disabled
at build time (by setting the `WITH_SIMD` CMake variable to `0`) in an AArch64
build of libjpeg-turbo.

- 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,

- 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.

- 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.

- 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.

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.
OBS-URL: https://build.opensuse.org/package/show/graphics/libjpeg-turbo?expand=0&rev=122
1. Fixed "using JNI after critical get" errors that occurred on Android
platforms when using any of the YUV encoding/compression/decompression/decoding
methods in the TurboJPEG Java API.
2. Fixed or worked around multiple issues with `jpeg_skip_scanlines()`:
- Fixed segfaults or "Corrupt JPEG data: premature end of data segment"
errors in `jpeg_skip_scanlines()` that occurred when decompressing 4:2:2 or
4:2:0 JPEG images using merged (non-fancy) upsampling/color conversion (that
is, when setting `cinfo.do_fancy_upsampling` to `FALSE`.) 2.0.0[6] was a
similar fix, but it did not cover all cases.
- `jpeg_skip_scanlines()` now throws an error if two-pass color
quantization is enabled. Two-pass color quantization never worked properly
with `jpeg_skip_scanlines()`, and the issues could not readily be fixed.
- Fixed an issue whereby `jpeg_skip_scanlines()` always returned 0 when
skipping past the end of an image.
3. The Arm 64-bit (Armv8) Neon SIMD extensions can now be built using MinGW
toolchains targetting Arm64 (AArch64) Windows binaries.
4. Fixed unexpected visual artifacts that occurred when using
`jpeg_crop_scanline()` and interblock smoothing while decompressing only the DC
scan of a progressive JPEG image.
5. Fixed an issue whereby libjpeg-turbo would not build if 12-bit-per-component
JPEG support (`WITH_12BIT`) was enabled along with libjpeg v7 or libjpeg v8
API/ABI emulation (`WITH_JPEG7` or `WITH_JPEG8`.)

- Update to version 2.0.5
* Worked around issues in the MIPS DSPr2 SIMD extensions that caused failures
in the libjpeg-turbo regression tests. Specifically, the
jsimd_h2v1_downsample_dspr2() and jsimd_h2v2_downsample_dspr2() functions
in the MIPS DSPr2 SIMD extensions are now disabled until/unless they can be
fixed, and other functions that are incompatible with big endian MIPS CPUs
are disabled when building libjpeg-turbo for such CPUs.
* Fixed an oversight in the TJCompressor.compress(int) method in the
TurboJPEG Java API that caused an error ("java.lang.IllegalStateException:
No source image is associated with this instance") when attempting to use
that method to compress a YUV image.
* Fixed an issue (CVE-2020-13790) in the PPM reader that caused a buffer
overrun in cjpeg, TJBench, or the tjLoadImage() function if one of the
values in a binary PPM/PGM input file exceeded the maximum value defined in
the file's header and that maximum value was less than 255. libjpeg-turbo
1.5.0 already included a similar fix for binary PPM/PGM files with maximum
values greater than 255.
* The TurboJPEG API library's global error handler, which is used in
functions such as tjBufSize() and tjLoadImage() that do not require a
TurboJPEG instance handle, is now thread-safe on platforms that support
thread-local storage.

- Upate to version 2.0.4:
- bug 388 was fixed upstream
https://github.com/libjpeg-turbo/libjpeg-turbo/issues/388
- removed patches, as it is included in this release.
* Fixed a regression in the Windows packaging system
(introduced by 2.0 beta1[2]) whereby, if both the 64-bit libjpeg-turbo
SDK for GCC and the 64-bit libjpeg-turbo SDK for Visual C++ were installed
on the same system, only one of them could be uninstalled.
* Fixed a signed integer overflow and subsequent segfault that occurred when
attempting to decompress images with more than 715827882 pixels using the 64-bit C version of TJBench.
* Fixed out-of-bounds write in tjDecompressToYUV2() and tjDecompressToYUVPlanes()
(sometimes manifesting as a double free) that occurred when attempting to decompress
grayscale JPEG images that were compressed with a sampling factor other than 1
(for instance, with cjpeg -grayscale -sample 2x2).
* Fixed a regression introduced by 2.0.2[5] that caused the TurboJPEG API to incorrectly
identify some JPEG images with unusual sampling factors as 4:4:4 JPEG images.
This was known to cause a buffer overflow when attempting to decompress some such images using
tjDecompressToYUV2() or tjDecompressToYUVPlanes().
* Fixed an issue, detected by ASan, whereby attempting to losslessly transform a specially-crafted
malformed JPEG image containing an extremely-high-frequency coefficient block
(junk image data that could never be generated by a legitimate JPEG compressor) could cause the
Huffman encoder's local buffer to be overrun. (Refer to 1.4.0[9] and 1.4beta1[15].)
Given that the buffer overrun was fully contained within the stack and did not cause a segfault
or other user-visible errant behavior, and given that the lossless transformer (unlike the decompressor)
is not generally exposed to arbitrary data exploits, this issue did not likely pose a security risk.
The ARM 64-bit (ARMv8) NEON SIMD assembly code now stores constants in a separate read-only data
section rather than in the text section, to support execute-only memory layouts.

1. Fixed a regression introduced by 2.0.1[5] that prevented a runtime search
path (rpath) from being embedded in the libjpeg-turbo shared libraries and
executables for macOS and iOS. This caused a fatal error of the form
"dyld: Library not loaded" when attempting to use one of the executables,
unless `DYLD_LIBRARY_PATH` was explicitly set to the location of the
libjpeg-turbo shared libraries.
2. Fixed an integer overflow and subsequent segfault (CVE-2018-20330) that
occurred when attempting to load a BMP file with more than 1 billion pixels
using the `tjLoadImage()` function.
3. Fixed a buffer overrun (CVE-2018-19664) that occurred when attempting to
decompress a specially-crafted malformed JPEG image to a 256-color BMP using
djpeg.
4. Fixed a floating point exception that occurred when attempting to
decompress a specially-crafted malformed JPEG image with a specified image
width or height of 0 using the C version of TJBench.
5. The TurboJPEG API will now decompress 4:4:4 JPEG images with 2x1, 1x2, 3x1,
or 1x3 luminance and chrominance sampling factors. This is a non-standard way
of specifying 1x subsampling (normally 4:4:4 JPEGs have 1x1 luminance and
chrominance sampling factors), but the JPEG format and the libjpeg API both
allow it.
6. Fixed a regression introduced by 2.0 beta1[7] that caused djpeg to generate
incorrect PPM images when used with the `-colors` option.
7. Fixed an issue whereby a static build of libjpeg-turbo (a build in which
`ENABLE_SHARED` is `0`) could not be installed using the Visual Studio IDE.
8. Fixed a severe performance issue in the Loongson MMI SIMD extensions that
occurred when compressing RGB images whose image rows were not 64-bit-aligned.

1. Fixed a NullPointerException in the TurboJPEG Java wrapper that occurred
when using the YUVImage constructor that creates an instance backed by separate
image planes and allocates memory for the image planes.
2. Fixed an issue whereby the Java version of TJUnitTest would fail when
testing BufferedImage encoding/decoding on big endian systems.
3. Fixed a segfault in djpeg that would occur if an output format other than
PPM/PGM was selected along with the `-crop` option. The `-crop` option now
works with the GIF and Targa formats as well (unfortunately, it cannot be made
to work with the BMP and RLE formats due to the fact that those output engines
write scanlines in bottom-up order.) djpeg will now exit gracefully if an
output format other than PPM/PGM, GIF, or Targa is selected along with the
`-crop` option.
4. Fixed an issue whereby `jpeg_skip_scanlines()` would segfault if color
quantization was enabled.
5. TJBench (both C and Java versions) will now display usage information if any
command-line argument is unrecognized. This prevents the program from silently
ignoring typos.
6. Fixed an access violation in tjbench.exe (Windows) that occurred when the
program was used to decompress an existing JPEG image.
7. Fixed an ArrayIndexOutOfBoundsException in the TJExample Java program that
occurred when attempting to decompress a JPEG image that had been compressed
with 4:1:1 chrominance subsampling.
8. Fixed an issue whereby, when using `jpeg_skip_scanlines()` to skip to the
end of a single-scan (non-progressive) image, subsequent calls to
`jpeg_consume_input()` would return `JPEG_SUSPENDED` rather than
`JPEG_REACHED_EOI`.
9. `jpeg_crop_scanlines()` now works correctly when decompressing grayscale
JPEG images that were compressed with a sampling factor other than 1 (for
instance, with `cjpeg -grayscale -sample 2x2`).

max_memory_to_use structure member in jpeg_memory_mgr,
which can be set to the maximum amount of memory (in bytes)
that libjpeg-turbo should use during decompression or
multi-pass (including progressive) compression. This limit
can also be set using the JPEGMEM environment variable or
using the -maxmemory switch in cjpeg/djpeg/jpegtran.

+ The libjpeg-turbo memory manager will now honor the

+ Fix for PowerPC platforms lacking AltiVec instructions
+ Fix ABI problem with clang/llvm on aarch64.
+ Fancy upsampling is now supported when decompressing JPEG
images that use 4:4:0 (h1v2) chroma subsampling.
+ If merged upsampling isn't SIMD-accelerated but YCbCr-to-RGB
conversion is, then libjpeg-turbo will now disable merged
upsampling when decompressing YCbCr JPEG images into RGB
or extended RGB output images. This significantly speeds up
the decompression of 4:2:0 and 4:2:2 JPEGs on ARM platforms
if fancy upsampling is not used
(for example, if the -nosmooth option to djpeg is specified.)
+ The TurboJPEG API will now decompress 4:2:2 and 4:4:0 JPEG
images with 2x2 luminance sampling factors and 2x1 or 1x2
chrominance sampling factors.
+ Fixed an unsigned integer overflow in the libjpeg memory manager.
+ Fixed additional negative left shifts and other issues reported
by the GCC and Clang undefined behavior sanitizers when
attempting to decompress specially-crafted malformed JPEG
images. None of these issues posed a security threat, but
removing the warnings makes it easier to detect actual
security issues, should they arise in the future.
+ Fixed an out-of-bounds array reference, introduced by
1.4.902 and detected by the Clang undefined behavior sanitizer,
that could be triggered by a specially-crafted malformed
JPEG image with more than four components. Because the
out-of-bounds reference was still within the same structure,
it was not known to pose a security threat, but removing
the warning makes it easier to detect actual security issues,
should they arise in the future.

+ Fixed an issue whereby a malformed motion-JPEG frame could
cause the "fast path" of libjpeg-turbo's Huffman decoder to
read from uninitialized memory.
+ Added libjpeg-turbo version and build information to the global
string table of the libjpeg and TurboJPEG API libraries.
+ Fixed a couple of issues in the PPM reader that would cause
buffer overruns in cjpeg if one of the values in a binary
PPM/PGM input file exceeded the maximum value defined in the
file's header. libjpeg-turbo 1.4.2 already included a similar
fix for ASCII PPM/PGM files. Note that these issues were not
security bugs, since they were confined to the cjpeg program
and did not affect any of the libjpeg-turbo libraries.
+ Fixed an issue whereby attempting to decompress a JPEG file with
a corrupt header using the tjDecompressToYUV2() function would
cause the function to abort without returning an error and,
under certain circumstances, corrupt the stack. This only
occurred if tjDecompressToYUV2() was called prior to calling
tjDecompressHeader3(), or if the return value from
tjDecompressHeader3() was ignored (both cases represent
incorrect usage of the TurboJPEG API.)
+ The jpeg_stdio_src(), jpeg_mem_src(), jpeg_stdio_dest(),
and jpeg_mem_dest() functions in the libjpeg API will now
throw an error if a source/destination manager has already
been assigned to the compress or decompress object by a
different function or by the calling program.
- Update to version 1.5.0
+ Fixed an issue whereby a malformed motion-JPEG frame could
cause the "fast path" of libjpeg-turbo's Huffman decoder to
