package/jpeg-turbo: security bump to version 2.0.3
Fixes the following security vulnerabilities:
- CVE-2019-2201: In generate_jsimd_ycc_rgb_convert_neon of
jsimd_arm64_neon.S, there is a possible out of bounds write due to a
missing bounds check. This could lead to remote code execution in an
unprivileged process with no additional execution privileges needed.
For more details, see the upstream bugtracker:
https://github.com/libjpeg-turbo/libjpeg-turbo/issues/361
Additionally, it fixes a number of other issues. From the release notes:
- Fixed a regression in the SIMD feature detection code, introduced by the
AVX2 SIMD extensions (2.0 beta1[1]), that was known to cause an illegal
instruction exception, in rare cases, on CPUs that lack support for CPUID
leaf 07H (or on which the maximum CPUID leaf has been limited by way of a
BIOS setting.)
- The 4:4:0 (h1v2) fancy (smooth) chroma upsampling algorithm in the
decompressor now uses a similar bias pattern to that of the 4:2:2 (h2v1)
fancy chroma upsampling algorithm, rounding up or down the upsampled
result for alternate pixels rather than always rounding down. This
ensures that, regardless of whether a 4:2:2 JPEG image is rotated or
transposed prior to decompression (in the frequency domain) or after
decompression (in the spatial domain), the final image will be similar.
- Fixed a regression introduced by 2.0 beta1[15] whereby attempting to
generate a progressive JPEG image on an SSE2-capable CPU using a scan
script containing one or more scans with lengths divisible by 16 would
result in an error ("Missing Huffman code table entry") and an invalid
JPEG image.
- Fixed an issue whereby tjDecodeYUV() and tjDecodeYUVPlanes() would throw
an error ("Invalid progressive parameters") or a warning ("Inconsistent
progression sequence") if passed a TurboJPEG instance that was previously
used to decompress a progressive JPEG image.
