libjpeg-turbo: update 1.4.1 -> 1.4.2
https://github.com/libjpeg-turbo/libjpeg-turbo/blob/1.4.2/ChangeLog.txt
1.4.2
=====
[1] Fixed an issue whereby cjpeg would segfault if a Windows bitmap with a
negative width or height was used as an input image (Windows bitmaps can have
a negative height if they are stored in top-down order, but such files are
rare and not supported by libjpeg-turbo.)
[2] Fixed an issue whereby, under certain circumstances, libjpeg-turbo would
incorrectly encode certain JPEG images when quality=100 and the fast integer
forward DCT were used. This was known to cause 'make test' to fail when the
library was built with '-march=haswell' on x86 systems.
[3] Fixed an issue whereby libjpeg-turbo would crash when built with the latest
& greatest development version of the Clang/LLVM compiler. This was caused by
an x86-64 ABI conformance issue in some of libjpeg-turbo's 64-bit SSE2 SIMD
routines. Those routines were incorrectly using a 64-bit mov instruction to
transfer a 32-bit JDIMENSION argument, whereas the x86-64 ABI allows the upper
(unused) 32 bits of a 32-bit argument's register to be undefined. The new
Clang/LLVM optimizer uses load combining to transfer multiple adjacent 32-bit
structure members into a single 64-bit register, and this exposed the ABI
conformance issue.
[4] Fixed a bug in the MIPS DSPr2 4:2:0 "plain" (non-fancy and non-merged)
upsampling routine that caused a buffer overflow (and subsequent segfault) when
decompressing a 4:2:0 JPEG image whose scaled output width was less than 16
pixels. The "plain" upsampling routines are normally only used when
decompressing a non-YCbCr JPEG image, but they are also used when decompressing
a JPEG image whose scaled output height is 1.
[5] Fixed various negative left shifts and other issues reported by the GCC and
Clang undefined behavior sanitizers. None of these was known to pose a
security threat, but removing the warnings makes it easier to detect actual
security issues, should they arise in the future.
