Changelog for libjpeg8-x86-64-v3-8.2.2-4.20.x86_64.rpm :

* 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
* 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.
