Changelog for libjpeg8-8.3.2-255.1.i586.rpm :

* Sat Sep 28 2024 Dirk Müller - 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 - 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 - 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.
* Mon Jan 15 2024 Andreas Schwab - Do not require SIMD support when it does not exist
* Mon Jan 01 2024 Dirk Müller - 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.
* Fri Jun 23 2023 pgajdosAATTsuse.com- merge two spec files into one
* Thu May 04 2023 Dominique Leuenberger - Add _multibuild to define 2nd spec file as additional flavor. Eliminates the need for source package links in OBS.
* Wed Mar 08 2023 Martin Pluskal - Build AVX2 enabled hwcaps library for x86_64-v3
* Tue Feb 21 2023 Paolo Stivanin - 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.
* Sat Dec 24 2022 Dirk Stoecker - Add explicit provides for jpegtran, so it can be installed easier
* Wed Aug 17 2022 Dirk Müller - 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 - 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.
* Tue Jul 05 2022 Jan Engelhardt - Add requires between baselibs
* Mon Apr 18 2022 Cristian Rodríguez - Use nasm instead of yasm, the latter has not released any update in 7 years.
* Sun Mar 20 2022 Dirk Müller - 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 - 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.
* Wed Sep 29 2021 pgajdosAATTsuse.com- previous version updates fixes following bugs: CVE-2014-9092, CVE-2018-14498, CVE-2019-2201, CVE-2020-17541 (bsc#1128712, bsc#1186764, bsc#807183, bsc#906761)
* Fri Aug 20 2021 pgajdosAATTsuse.com- 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.
