- 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

Dirk Mueller (dirkmueller) 4 months ago (revision 149)

- 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

  =====
  * 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

    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.

Paolo Stivanin (polslinux) about 1 year ago (revision 136)

- 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,
