- update to 3.0.4:
* Fixed an issue whereby the CPU usage of the default marker
processor in the decompressor grew exponentially with the
number of markers. This caused an unreasonable slow-down in
`jpeg_read_header()` if an application called `jpeg_save_markers()`
to save markers of a particular type and then attempted to
decompress a JPEG image containing an excessive number of markers
of that type.
* Hardened the default marker processor in the decompressor to guard
against an issue (exposed by 3.0 beta2[6]) whereby attempting to
decompress a specially-crafted malformed JPEG image (specifically
an image with a complete 12-bit-per-sample Start Of Frame segment
followed by an incomplete 8-bit-per-sample Start Of Frame segment)
using buffered-image mode and input prefetching caused a segfault
if the `fill_input_buffer()` method in the calling application's
custom source manager incorrectly returned `FALSE` in response to a
prematurely-terminated JPEG data stream.
* Fixed an issue in cjpeg whereby, when generating a
12-bit-per-sample or 16-bit-per-sample lossless JPEG image,
specifying a point transform value greater than 7 resulted in an
error ("Invalid progressive/lossless parameters") unless the
`-precision` option was specified before the `-lossless` option.
* Fixed a regression introduced by 3.0.3[3] that made it impossible
for calling applications to generate 12-bit-per-sample
arithmetic-coded lossy JPEG images using the TurboJPEG API.
* Fixed an error ("Destination buffer is not large enough") that
occurred when attempting to generate a full-color lossless JPEG
image using the TurboJPEG Java API's `byte[]
TJCompressor.compress()` method if the value of `TJ.PARAM_SUBSAMP`
was not `TJ.SAMP_444`. (forwarded request 1204571 from dirkmueller)

specifying the maximum amount of memory (in megabytes) that
will be allocated for intermediate buffers, which are used

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

* 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

JCS_EXT_RGBA, the alpha channel was set to 255 rather than 4095.

accept "abbreviated table specification" (AKA "tables-only") datastreams,
which can be used to prime the decompressor with quantization and Huffman
tables that can be used when decompressing subsequent "abbreviated image"
datastreams.

* Fixed an error ("Bogus virtual array access") that occurred when
attempting to decompress a progressive JPEG image with a height less than
or equal to one iMCU (8 * the vertical sampling factor) using
buffered-image mode with interblock smoothing enabled. This was a
regression introduced by 2.1 beta1[6(b)].
* Fixed two issues that prevented partial image decompression from working
properly with buffered-image mode:
* Attempting to call jpeg_crop_scanline() after jpeg_start_decompress()
but before jpeg_start_output() resulted in an error ("Improper call to
JPEG library in state 207".)
* Attempting to use jpeg_skip_scanlines() resulted in an error ("Bogus

GAS implementations of AArch64 (Arm 64-bit) Neon SIMD functions (which are used
by default with GCC for performance reasons) to be placed in the `.rodata`
section rather than in the `.text` section. This caused the GNU linker to
automatically place the `.rodata` section in an executable segment, which
prevented libjpeg-turbo from working properly with other linkers and also
represented a potential security risk.
* Fixed an issue whereby the `tjTransform()` function incorrectly computed the
MCU block size for 4:4:4 JPEG images with non-unary sampling factors and thus
unduly rejected some cropping regions, even though those regions aligned with
8x8 MCU block boundaries.
* Fixed a regression introduced by 2.1 beta1[13] that caused the build system

2. Fixed a regression introduced by 2.1 beta1[13] that prevented the
Arm 32-bit (AArch32) Neon SIMD extensions from building unless
the C compiler flags included -mfloat-abi=softfp or -mfloat-abi=hard.

reliance on undefined C compiler behavior led to crashes
("SIGBUS: illegal alignment") on Android systems when running
AArch32/Thumb builds of libjpeg-turbo built with recent versions
of Clang.

it to copy only the ICC profile markers from the source file and
discard any other metadata.

1. Fixed "using JNI after critical get" errors that occurred on Android
platforms when using any of the YUV encoding/compression/decompression/decoding
methods in the TurboJPEG Java API.
2. Fixed or worked around multiple issues with `jpeg_skip_scanlines()`:
- Fixed segfaults or "Corrupt JPEG data: premature end of data segment"
errors in `jpeg_skip_scanlines()` that occurred when decompressing 4:2:2 or
4:2:0 JPEG images using merged (non-fancy) upsampling/color conversion (that
is, when setting `cinfo.do_fancy_upsampling` to `FALSE`.) 2.0.0[6] was a
similar fix, but it did not cover all cases.
- `jpeg_skip_scanlines()` now throws an error if two-pass color
quantization is enabled. Two-pass color quantization never worked properly
with `jpeg_skip_scanlines()`, and the issues could not readily be fixed.
- Fixed an issue whereby `jpeg_skip_scanlines()` always returned 0 when
skipping past the end of an image.
3. The Arm 64-bit (Armv8) Neon SIMD extensions can now be built using MinGW
toolchains targetting Arm64 (AArch64) Windows binaries.
4. Fixed unexpected visual artifacts that occurred when using
`jpeg_crop_scanline()` and interblock smoothing while decompressing only the DC
scan of a progressive JPEG image.
5. Fixed an issue whereby libjpeg-turbo would not build if 12-bit-per-component
JPEG support (`WITH_12BIT`) was enabled along with libjpeg v7 or libjpeg v8
API/ABI emulation (`WITH_JPEG7` or `WITH_JPEG8`.)

4:2:0 JPEG images using merged (non-fancy) upsampling/color conversion (that
is, when setting `cinfo.do_fancy_upsampling` to `FALSE`.) 2.0.0[6] was a
similar fix, but it did not cover all cases.
- `jpeg_skip_scanlines()` now throws an error if two-pass color
quantization is enabled. Two-pass color quantization never worked properly
with `jpeg_skip_scanlines()`, and the issues could not readily be fixed.
- Fixed an issue whereby `jpeg_skip_scanlines()` always returned 0 when
skipping past the end of an image.
3. The Arm 64-bit (Armv8) Neon SIMD extensions can now be built using MinGW
toolchains targetting Arm64 (AArch64) Windows binaries.
4. Fixed unexpected visual artifacts that occurred when using
`jpeg_crop_scanline()` and interblock smoothing while decompressing only the DC
scan of a progressive JPEG image.
5. Fixed an issue whereby libjpeg-turbo would not build if 12-bit-per-component
JPEG support (`WITH_12BIT`) was enabled along with libjpeg v7 or libjpeg v8
API/ABI emulation (`WITH_JPEG7` or `WITH_JPEG8`.)

- Update to version 2.0.5
* Worked around issues in the MIPS DSPr2 SIMD extensions that caused failures
in the libjpeg-turbo regression tests. Specifically, the
jsimd_h2v1_downsample_dspr2() and jsimd_h2v2_downsample_dspr2() functions
in the MIPS DSPr2 SIMD extensions are now disabled until/unless they can be
fixed, and other functions that are incompatible with big endian MIPS CPUs
are disabled when building libjpeg-turbo for such CPUs.
* Fixed an oversight in the TJCompressor.compress(int) method in the
TurboJPEG Java API that caused an error ("java.lang.IllegalStateException:
No source image is associated with this instance") when attempting to use
that method to compress a YUV image.
* Fixed an issue (CVE-2020-13790) in the PPM reader that caused a buffer
overrun in cjpeg, TJBench, or the tjLoadImage() function if one of the
values in a binary PPM/PGM input file exceeded the maximum value defined in
the file's header and that maximum value was less than 255. libjpeg-turbo
1.5.0 already included a similar fix for binary PPM/PGM files with maximum
values greater than 255.
* The TurboJPEG API library's global error handler, which is used in
functions such as tjBufSize() and tjLoadImage() that do not require a
TurboJPEG instance handle, is now thread-safe on platforms that support
thread-local storage.
- Fix source verification
- Drop patches fixed upstream:
* ctest-depends.patch
