Changelog for libjpeg8-32bit-8.1.2-107.1.x86_64.rpm :
Wed Jan 18 13:00:00 2017
- set build date to enable reproducible builds

Wed Sep 21 14:00:00 2016
- Update to version 1.5.1
+ Fix for PowerPC platforms lacking AltiVec instructions
+ Fix ABI problem with clang/llvm on aarch64.
+ Fancy upsampling is now supported when decompressing JPEG
images that use 4:4:0 (h1v2) chroma subsampling.
+ If merged upsampling isn\'t SIMD-accelerated but YCbCr-to-RGB
conversion is, then libjpeg-turbo will now disable merged
upsampling when decompressing YCbCr JPEG images into RGB
or extended RGB output images. This significantly speeds up
the decompression of 4:2:0 and 4:2:2 JPEGs on ARM platforms
if fancy upsampling is not used
(for example, if the -nosmooth option to djpeg is specified.)
+ The TurboJPEG API will now decompress 4:2:2 and 4:4:0 JPEG
images with 2x2 luminance sampling factors and 2x1 or 1x2
chrominance sampling factors.
+ Fixed an unsigned integer overflow in the libjpeg memory manager.
+ Fixed additional negative left shifts and other issues reported
by the GCC and Clang undefined behavior sanitizers when
attempting to decompress specially-crafted malformed JPEG
images. None of these issues posed a security threat, but
removing the warnings makes it easier to detect actual
security issues, should they arise in the future.
+ Fixed an out-of-bounds array reference, introduced by
1.4.902 and detected by the Clang undefined behavior sanitizer,
that could be triggered by a specially-crafted malformed
JPEG image with more than four components. Because the
out-of-bounds reference was still within the same structure,
it was not known to pose a security threat, but removing
the warning makes it easier to detect actual security issues,
should they arise in the future.

Wed Jun 8 14:00:00 2016
- Update to version 1.5.0
+ Fixed an issue whereby a malformed motion-JPEG frame could
cause the \"fast path\" of libjpeg-turbo\'s Huffman decoder to
read from uninitialized memory.
+ Added libjpeg-turbo version and build information to the global
string table of the libjpeg and TurboJPEG API libraries.
+ Fixed a couple of issues in the PPM reader that would cause
buffer overruns in cjpeg if one of the values in a binary
PPM/PGM input file exceeded the maximum value defined in the
file\'s header. libjpeg-turbo 1.4.2 already included a similar
fix for ASCII PPM/PGM files. Note that these issues were not
security bugs, since they were confined to the cjpeg program
and did not affect any of the libjpeg-turbo libraries.
+ Fixed an issue whereby attempting to decompress a JPEG file with
a corrupt header using the tjDecompressToYUV2() function would
cause the function to abort without returning an error and,
under certain circumstances, corrupt the stack. This only
occurred if tjDecompressToYUV2() was called prior to calling
tjDecompressHeader3(), or if the return value from
tjDecompressHeader3() was ignored (both cases represent
incorrect usage of the TurboJPEG API.)
+ The jpeg_stdio_src(), jpeg_mem_src(), jpeg_stdio_dest(),
and jpeg_mem_dest() functions in the libjpeg API will now
throw an error if a source/destination manager has already
been assigned to the compress or decompress object by a
different function or by the calling program.

Thu Oct 8 14:00:00 2015

dependent on directory structure.

Mon Mar 2 13:00:00 2015
- Remove float tests with new libjpeg-turbo-remove-test.patch
same as Fedora bug 1161585 related to upstream issue

Sat Jan 10 13:00:00 2015
- Update to version 1.4.0
+ Fixed a build issue on OS X PowerPC platforms (md5cmp failed to build
because OS X does not provide the le32toh() and htole32() functions.)
+ The non-SIMD RGB565 color conversion code did not work correctly on big
endian machines. This has been fixed.
+ Fixed an issue in tjPlaneSizeYUV() whereby it would erroneously return 1
instead of -1 if componentID was > 0 and subsamp was TJSAMP_GRAY.
+ Fixed an issue in tjBufSizeYUV2() wherby it would erroneously return 0
instead of -1 if width was < 1.
+ The Huffman encoder now uses clz and bsr instructions for bit counting on
ARM64 platforms (see 1.4 beta1 [5].)
+ The close() method in the TJCompressor and TJDecompressor Java classes is
now idempotent. Previously, that method would call the native tjDestroy()
function even if the TurboJPEG instance had already been destroyed. This
caused an exception to be thrown during finalization, if the close() method had
already been called. The exception was caught, but it was still an expensive
+ The TurboJPEG API previously generated an error (\"Could not determine
subsampling type for JPEG image\") when attempting to decompress grayscale JPEG
images that were compressed with a sampling factor other than 1 (for instance,
with \'cjpeg -grayscale -sample 2x2\'). Subsampling technically has no meaning
with grayscale JPEGs, and thus the horizontal and vertical sampling factors
for such images are ignored by the decompressor. However, the TurboJPEG API
was being too rigid and was expecting the sampling factors to be equal to 1
before it treated the image as a grayscale JPEG.
+ cjpeg, djpeg, and jpegtran now accept an argument of -version, which will
print the library version and exit.
+ Referring to 1.4 beta1 [15], another extremely rare circumstance was
discovered under which the Huffman encoder\'s local buffer can be overrun
when a buffered destination manager is being used and an
extremely-high-frequency block (basically junk image data) is being encoded.
Even though the Huffman local buffer was increased from 128 bytes to 136 bytes
to address the previous issue, the new issue caused even the larger buffer to
be overrun. Further analysis reveals that, in the absolute worst case (such as
setting alternating AC coefficients to 32767 and -32768 in the JPEG scanning
order), the Huffman encoder can produce encoded blocks that approach double the
size of the unencoded blocks. Thus, the Huffman local buffer was increased to
256 bytes, which should prevent any such issue from re-occurring in the future.
+ The new tjPlaneSizeYUV(), tjPlaneWidth(), and tjPlaneHeight() functions
were not actually usable on any platform except OS X and Windows, because
those functions were not included in the libturbojpeg mapfile. This has been
+ Restored the JPP(), JMETHOD(), and FAR macros in the libjpeg-turbo header
files. The JPP() and JMETHOD() macros were originally implemented in libjpeg
as a way of supporting non-ANSI compilers that lacked support for prototype
parameters. libjpeg-turbo has never supported such compilers, but some
software packages still use the macros to define their own prototypes.
Similarly, libjpeg-turbo has never supported MS-DOS and other platforms that
have far symbols, but some software packages still use the FAR macro. A pretty
good argument can be made that this is a bad practice on the part of the
software in question, but since this affects more than one package, it\'s just
easier to fix it here.
+ Fixed issues that were preventing the ARM 64-bit SIMD code from compiling
for iOS, and included an ARMv8 architecture in all of the binaries installed by
the \"official\" libjpeg-turbo SDK for OS X.

cause libjpeg-turbo to use uninitialized memory during

that occurred when calling the TurboJPEG YUV encoding function
with a very small (< 5x5) source image, and added a unit test
to check for this error.

Thu May 19 14:00:00 2011
- updated to 1.1.1:

* Fixed a 1-pixel error in row 0, column 21 of the luminance
plane generated by tjEncodeYUV().

* libjpeg-turbo\'s accelerated Huffman decoder previously
ignored unexpected markers found in the middle of the
JPEG data stream during decompression. It will now
hand off decoding of a particular block to the unaccelerated
Huffman decoder if an unexpected marker is found, so that
the unaccelerated Huffman decoder can generate an appropriate

* Fixed a bug in jpeg_read_coefficients() whereby it would
not initialize cinfo->image_width and cinfo->image_height
if libjpeg v7 or v8 emulation was enabled. This specifically
caused the jpegoptim program to fail if it was linked against
a version of libjpeg-turbo that was built with libjpeg v7 or
v8 emulation.

BMP files in cjpeg.
