- 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 (forwarded request 1144368 from mnhauke)

- 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 (forwarded request 1136025 from dirkmueller)

- 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, (forwarded request 1066935 from polslinux)

- Add explicit provides for jpegtran, so it can be installed easier Adds an explicit provides line, so that "zypper in jpegtran" will work in future instead of having to search which package contains it.

- 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.

- version update to 2.0.6 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`.) - modified sources % libjpeg-turbo.keyring

- 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. - Fix source verification - Drop patches fixed upstream: * ctest-depends.patch * libjpeg-turbo-CVE-2020-13790.patch - Run spec-cleaner * Remove package groups * Use make macros - Update to version 2.0.5 * Worked around issues in the MIPS DSPr2 SIMD extensions that caused failures in the libjpeg-turbo regression tests.
