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.

Buildroot is a simple, efficient and easy-to-use tool to generate embedded Linux systems through cross-compilation. The documentation can be found in docs/manual. You can generate a text document with 'make manual-text' and read output/docs/manual/manual.text. Online documentation can be found at http://buildroot.org/docs.html To build and use the buildroot stuff, do the following: 1) run 'make menuconfig' 2) select the target architecture and the packages you wish to compile 3) run 'make' 4) wait while it compiles 5) find the kernel, bootloader, root filesystem, etc. in output/images You do not need to be root to build or run buildroot. Have fun! Buildroot comes with a basic configuration for a number of boards. Run 'make list-defconfigs' to view the list of provided configurations. Please feed suggestions, bug reports, insults, and bribes back to the buildroot mailing list: buildroot@buildroot.org You can also find us on #buildroot on Freenode IRC. If you would like to contribute patches, please read https://buildroot.org/manual.html#submitting-patches
