Fixed a signed integer overflow and subsequent segfault that occurred when attempting to decompress images with more than 715827882 pixels using the 64-bit C version of TJBench. Fixed out-of-bounds write in tjDecompressToYUV2() and tjDecompressToYUVPlanes() (sometimes manifesting as a double free) that occurred when attempting to decompress grayscale JPEG images that were compressed with a sampling factor other than 1 (for instance, with cjpeg -grayscale -sample 2x2). Fixed a regression introduced by 2.0.2[5] that caused the TurboJPEG API to incorrectly identify some JPEG images with unusual sampling factors as 4:4:4 JPEG images. This was known to cause a buffer overflow when attempting to decompress some such images using tjDecompressToYUV2() or tjDecompressToYUVPlanes(). Fixed an issue, detected by ASan, whereby attempting to losslessly transform a specially-crafted malformed JPEG image containing an extremely-high-frequency coefficient block (junk image data that could never be generated by a legitimate JPEG compressor) could cause the Huffman encoder's local buffer to be overrun. (Refer to 1.4.0[9] and 1.4beta1[15].) Given that the buffer overrun was fully contained within the stack and did not cause a segfault or other user-visible errant behavior, and given that the lossless transformer (unlike the decompressor) is not generally exposed to arbitrary data exploits, this issue did not likely pose a security risk. The ARM 64-bit (ARMv8) NEON SIMD assembly code now stores constants in a separate read-only data section rather than in the text section, to support execute-only memory layouts. 2.0.3 Fixed "using JNI after critical get" errors that occurred on Android platforms when passing invalid arguments to certain methods in the TurboJPEG Java API. 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 an integer overflow and subsequent segfault that occurred when attempting to compress or decompress images with more than 1 billion pixels using the TurboJPEG API. 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. 2.0.2 Fixed a regression introduced by 2.0.1[5] that prevented a runtime search path (rpath) from being embedded in the libjpeg-turbo shared libraries and executables for macOS and iOS. This caused a fatal error of the form "dyld: Library not loaded" when attempting to use one of the executables, unless DYLD_LIBRARY_PATH was explicitly set to the location of the libjpeg-turbo shared libraries. Fixed an integer overflow and subsequent segfault (CVE-2018-20330) that occurred when attempting to load a BMP file with more than 1 billion pixels using the tjLoadImage() function. Fixed a buffer overrun (CVE-2018-19664) that occurred when attempting to decompress a specially-crafted malformed JPEG image to a 256-color BMP using djpeg. Fixed a floating point exception that occurred when attempting to decompress a specially-crafted malformed JPEG image with a specified image width or height of 0 using the C version of TJBench. The TurboJPEG API will now decompress 4:4:4 JPEG images with 2x1, 1x2, 3x1, or 1x3 luminance and chrominance sampling factors. This is a non-standard way of specifying 1x subsampling (normally 4:4:4 JPEGs have 1x1 luminance and chrominance sampling factors), but the JPEG format and the libjpeg API both allow it. Fixed a regression introduced by 2.0 beta1[7] that caused djpeg to generate incorrect PPM images when used with the -colors option. Fixed an issue whereby a static build of libjpeg-turbo (a build in which ENABLE_SHARED is 0) could not be installed using the Visual Studio IDE. Fixed a severe performance issue in the Loongson MMI SIMD extensions that occurred when compressing RGB images whose image rows were not 64-bit-aligned. 2.0.1 Fixed a regression introduced with the new CMake-based Un*x build system, whereby jconfig.h could cause compiler warnings of the form "HAVE_*_H" redefined if it was included by downstream Autotools-based projects that used AC_CHECK_HEADERS() to check for the existence of locale.h, stddef.h, or stdlib.h. The jsimd_quantize_float_dspr2() and jsimd_convsamp_float_dspr2() functions in the MIPS DSPr2 SIMD extensions are now disabled at compile time if the soft float ABI is enabled. Those functions use instructions that are incompatible with the soft float ABI. Fixed a regression in the SIMD feature detection code, introduced by the AVX2 SIMD extensions (2.0 beta1[1]), that caused libjpeg-turbo to crash on Windows 7 if Service Pack 1 was not installed. Fixed out-of-bounds read in cjpeg that occurred when attempting to compress a specially-crafted malformed color-index (8-bit-per-sample) Targa file in which some of the samples (color indices) exceeded the bounds of the Targa file's color table. Fixed an issue whereby installing a fully static build of libjpeg-turbo (a build in which CFLAGS contains -static and ENABLE_SHARED is 0) would fail with "No valid ELF RPATH or RUNPATH entry exists in the file." 2.0.0 The TurboJPEG API can now decompress CMYK JPEG images that have subsampled M and Y components (not to be confused with YCCK JPEG images, in which the C/M/Y components have been transformed into luma and chroma.) Previously, an error was generated ("Could not determine subsampling type for JPEG image") when such an image was passed to tjDecompressHeader3(), tjTransform(), tjDecompressToYUVPlanes(), tjDecompressToYUV2(), or the equivalent Java methods. Fixed an issue (CVE-2018-11813) whereby a specially-crafted malformed input file (specifically, a file with a valid Targa header but incomplete pixel data) would cause cjpeg to generate a JPEG file that was potentially thousands of times larger than the input file. The Targa reader in cjpeg was not properly detecting that the end of the input file had been reached prematurely, so after all valid pixels had been read from the input, the reader injected dummy pixels with values of 255 into the JPEG compressor until the number of pixels specified in the Targa header had been compressed. The Targa reader in cjpeg now behaves like the PPM reader and aborts compression if the end of the input file is reached prematurely. Because this issue only affected cjpeg and not the underlying library, and because it did not involve any out-of-bounds reads or other exploitable behaviors, it was not believed to represent a security threat. Fixed an issue whereby the tjLoadImage() and tjSaveImage() functions would produce a "Bogus message code" error message if the underlying bitmap and PPM readers/writers threw an error that was specific to the readers/writers (as opposed to a general libjpeg API error.) Fixed an issue (CVE-2018-1152) whereby a specially-crafted malformed BMP file, one in which the header specified an image width of 1073741824 pixels, would trigger a floating point exception (division by zero) in the tjLoadImage() function when attempting to load the BMP file into a 4-component image buffer. Fixed an issue whereby certain combinations of calls to jpeg_skip_scanlines() and jpeg_read_scanlines() could trigger an infinite loop when decompressing progressive JPEG images that use vertical chroma subsampling (for instance, 4:2:0 or 4:4:0.) Fixed a segfault in jpeg_skip_scanlines() that occurred when decompressing a 4:2:2 or 4:2:0 JPEG image using the merged (non-fancy) upsampling algorithms (that is, when setting cinfo.do_fancy_upsampling to FALSE.) The new CMake-based build system will now disable the MIPS DSPr2 SIMD extensions if it detects that the compiler does not support DSPr2 instructions. Fixed out-of-bounds read in cjpeg (CVE-2018-14498) that occurred when attempting to compress a specially-crafted malformed color-index (8-bit-per-sample) BMP file in which some of the samples (color indices) exceeded the bounds of the BMP file's color table. Fixed a signed integer overflow in the progressive Huffman decoder, detected by the Clang and GCC undefined behavior sanitizers, that could be triggered by attempting to decompress a specially-crafted malformed JPEG image. This issue did not pose a security threat, but removing the warning made it easier to detect actual security issues, should they arise in the future. @ text @$NetBSD: patch-aa,v 1.6 2018/08/13 20:50:59 gdt Exp $ --- Makefile.in.orig 2017-12-14 04:39:07.000000000 +0000 +++ Makefile.in @@@@ -573,7 +573,6 @@@@ build_vendor = @@build_vendor@@ builddir = @@builddir@@ datadir = @@datadir@@ datarootdir = @@datarootdir@@ -docdir = @@docdir@@ dvidir = @@dvidir@@ exec_prefix = @@exec_prefix@@ host = @@host@@ @@@@ -662,6 +661,7 @@@@ wrjpgcom_LDADD = libjpeg.la jcstest_SOURCES = jcstest.c jcstest_LDADD = libjpeg.la dist_man1_MANS = cjpeg.1 djpeg.1 jpegtran.1 rdjpgcom.1 wrjpgcom.1 +docdir = $(datadir)/doc/libjpeg-turbo DOCS = coderules.txt jconfig.txt change.log rdrle.c wrrle.c BUILDING.md \ ChangeLog.md @ 1.6 log @libjpeg-turbo: update to 1.5.3 Upstream changes are basically many bugfixes and a few performance improvements. @ text @d1 1 a1 1 $NetBSD: patch-aa,v 1.5 2016/06/14 12:07:58 wiz Exp $ @ 1.5 log @Updated libjpeg-turbo to 1.5.0. 1.5.0 ===== ### Significant changes relative to 1.5 beta1: 1. 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. 2. Added libjpeg-turbo version and build information to the global string table of the libjpeg and TurboJPEG API libraries. This is a common practice in other infrastructure libraries, such as OpenSSL and libpng, because it makes it easy to examine an application binary and determine which version of the library the application was linked against. 3. 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. 4. 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.) 5. Fixed an issue in the ARM 32-bit SIMD-accelerated Huffman encoder that prevented the code from assembling properly with clang. 6. 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. This prevents these functions from attempting to reuse a source/destination manager structure that was allocated elsewhere, because there is no way to ensure that it would be big enough to accommodate the new source/destination manager. 1.4.90 (1.5 beta1) ================== ### Significant changes relative to 1.4.2: 1. Added full SIMD acceleration for PowerPC platforms using AltiVec VMX (128-bit SIMD) instructions. Although the performance of libjpeg-turbo on PowerPC was already good, due to the increased number of registers available to the compiler vs. x86, it was still possible to speed up compression by about 3-4x and decompression by about 2-2.5x (relative to libjpeg v6b) through the use of AltiVec instructions. 2. Added two new libjpeg API functions (`jpeg_skip_scanlines()` and `jpeg_crop_scanline()`) that can be used to partially decode a JPEG image. See [libjpeg.txt](libjpeg.txt) for more details. 3. The TJCompressor and TJDecompressor classes in the TurboJPEG Java API now implement the Closeable interface, so those classes can be used with a try-with-resources statement. 4. The TurboJPEG Java classes now throw unchecked idiomatic exceptions (IllegalArgumentException, IllegalStateException) for unrecoverable errors caused by incorrect API usage, and those classes throw a new checked exception type (TJException) for errors that are passed through from the C library. 5. Source buffers for the TurboJPEG C API functions, as well as the `jpeg_mem_src()` function in the libjpeg API, are now declared as const pointers. This facilitates passing read-only buffers to those functions and ensures the caller that the source buffer will not be modified. This should not create any backward API or ABI incompatibilities with prior libjpeg-turbo releases. 6. The MIPS DSPr2 SIMD code can now be compiled to support either FR=0 or FR=1 FPUs. 7. Fixed additional negative left shifts and other issues reported by the GCC and Clang undefined behavior sanitizers. Most of these issues affected only 32-bit code, and none of them 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. 8. Removed the unnecessary `.arch` directive from the ARM64 NEON SIMD code. This directive was preventing the code from assembling using the clang integrated assembler. 9. Fixed a regression caused by 1.4.1[6] that prevented 32-bit and 64-bit libjpeg-turbo RPMs from being installed simultaneously on recent Red Hat/Fedora distributions. This was due to the addition of a macro in jconfig.h that allows the Huffman codec to determine the word size at compile time. Since that macro differs between 32-bit and 64-bit builds, this caused a conflict between the i386 and x86_64 RPMs (any differing files, other than executables, are not allowed when 32-bit and 64-bit RPMs are installed simultaneously.) Since the macro is used only internally, it has been moved into jconfigint.h. 10. The x86-64 SIMD code can now be disabled at run time by setting the `JSIMD_FORCENONE` environment variable to `1` (the other SIMD implementations already had this capability.) 11. Added a new command-line argument to TJBench (`-nowrite`) that prevents the benchmark from outputting any images. This removes any potential operating system overhead that might be caused by lazy writes to disk and thus improves the consistency of the performance measurements. 12. Added SIMD acceleration for Huffman encoding on SSE2-capable x86 and x86-64 platforms. This speeds up the compression of full-color JPEGs by about 10-15% on average (relative to libjpeg-turbo 1.4.x) when using modern Intel and AMD CPUs. Additionally, this works around an issue in the clang optimizer that prevents it (as of this writing) from achieving the same performance as GCC when compiling the C version of the Huffman encoder (). For the purposes of benchmarking or regression testing, SIMD-accelerated Huffman encoding can be disabled by setting the `JSIMD_NOHUFFENC` environment variable to `1`. 13. Added ARM 64-bit (ARMv8) NEON SIMD implementations of the commonly-used compression algorithms (including the slow integer forward DCT and h2v2 & h2v1 downsampling algorithms, which are not accelerated in the 32-bit NEON implementation.) This speeds up the compression of full-color JPEGs by about 75% on average on a Cavium ThunderX processor and by about 2-2.5x on average on Cortex-A53 and Cortex-A57 cores. 14. Added SIMD acceleration for Huffman encoding on NEON-capable ARM 32-bit and 64-bit platforms. For 32-bit code, this speeds up the compression of full-color JPEGs by about 30% on average on a typical iOS device (iPhone 4S, Cortex-A9) and by about 6-7% on average on a typical Android device (Nexus 5X, Cortex-A53 and Cortex-A57), relative to libjpeg-turbo 1.4.x. Note that the larger speedup under iOS is due to the fact that iOS builds use LLVM, which does not optimize the C Huffman encoder as well as GCC does. For 64-bit code, NEON-accelerated Huffman encoding speeds up the compression of full-color JPEGs by about 40% on average on a typical iOS device (iPhone 5S, Apple A7) and by about 7-8% on average on a typical Android device (Nexus 5X, Cortex-A53 and Cortex-A57), in addition to the speedup described in [13] above. For the purposes of benchmarking or regression testing, SIMD-accelerated Huffman encoding can be disabled by setting the `JSIMD_NOHUFFENC` environment variable to `1`. 15. pkg-config (.pc) scripts are now included for both the libjpeg and TurboJPEG API libraries on Un*x systems. Note that if a project's build system relies on these scripts, then it will not be possible to build that project with libjpeg or with a prior version of libjpeg-turbo. 16. Optimized the ARM 64-bit (ARMv8) NEON SIMD decompression routines to improve performance on CPUs with in-order pipelines. This speeds up the decompression of full-color JPEGs by nearly 2x on average on a Cavium ThunderX processor and by about 15% on average on a Cortex-A53 core. 17. Fixed an issue in the accelerated Huffman decoder that could have caused the decoder to read past the end of the input buffer when a malformed, specially-crafted JPEG image was being decompressed. In prior versions of libjpeg-turbo, the accelerated Huffman decoder was invoked (in most cases) only if there were > 128 bytes of data in the input buffer. However, it is possible to construct a JPEG image in which a single Huffman block is over 430 bytes long, so this version of libjpeg-turbo activates the accelerated Huffman decoder only if there are > 512 bytes of data in the input buffer. 18. Fixed a memory leak in tjunittest encountered when running the program with the `-yuv` option. 1.4.2 ===== ### Significant changes relative to 1.4.1: 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. @ text @d1 1 a1 1 $NetBSD: patch-aa,v 1.4 2015/07/21 21:37:12 rjs Exp $ d3 1 a3 1 --- Makefile.in.orig 2016-06-07 17:33:56.000000000 +0000 d13 4 a16 4 @@@@ -654,6 +653,7 @@@@ djpeg_SOURCES = cdjpeg.h cderror.h cdjpe djpeg_LDADD = libjpeg.la djpeg_CFLAGS = -DGIF_SUPPORTED -DPPM_SUPPORTED $(am__append_16) jpegtran_SOURCES = jpegtran.c rdswitch.c cdjpeg.c transupp.c transupp.h d18 3 a20 3 jpegtran_LDADD = libjpeg.la rdjpgcom_SOURCES = rdjpgcom.c rdjpgcom_LDADD = libjpeg.la @ 1.4 log @Update to 1.4.1.

Changes: 1.4.0 ===== [2] The non-SIMD RGB565 color conversion code did not work correctly on big endian machines. This has been fixed. [3] Fixed an issue in tjPlaneSizeYUV() whereby it would erroneously return 1 instead of -1 if componentID was > 0 and subsamp was TJSAMP_GRAY. [3] Fixed an issue in tjBufSizeYUV2() wherby it would erroneously return 0 instead of -1 if width was < 1. [5] The Huffman encoder now uses clz and bsr instructions for bit counting on ARM64 platforms (see 1.4 beta1 [5].) [6] 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 operation. [7] 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. [8] cjpeg, djpeg, and jpegtran now accept an argument of -version, which will print the library version and exit. [9] 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. 1.3.90 (1.4 beta1) ================== [1] New features in the TurboJPEG API: -- YUV planar images can now be generated with an arbitrary line padding (previously only 4-byte padding, which was compatible with X Video, was supported.) -- The decompress-to-YUV function has been extended to support image scaling. -- JPEG images can now be compressed from YUV planar source images. -- YUV planar images can now be decoded into RGB or grayscale images. -- 4:1:1 subsampling is now supported. This is mainly included for compatibility, since 4:1:1 is not fully accelerated in libjpeg-turbo and has no significant advantages relative to 4:2:0. -- CMYK images are now supported. This feature allows CMYK source images to be compressed to YCCK JPEGs and YCCK or CMYK JPEGs to be decompressed to CMYK destination images. Conversion between CMYK/YCCK and RGB or YUV images is not supported. Such conversion requires a color management system and is thus out of scope for a codec library. -- The handling of YUV images in the Java API has been significantly refactored and should now be much more intuitive. -- The Java API now supports encoding a YUV image from an arbitrary position in a large image buffer. -- All of the YUV functions now have a corresponding function that operates on separate image planes instead of a unified image buffer. This allows for compressing/decoding from or decompressing/encoding to a subregion of a larger YUV image. It also allows for handling YUV formats that swap the order of the U and V planes. [2] Added SIMD acceleration for DSPr2-capable MIPS platforms. This speeds up the compression of full-color JPEGs by 70-80% on such platforms and decompression by 25-35%. [3] If an application attempts to decompress a Huffman-coded JPEG image whose header does not contain Huffman tables, libjpeg-turbo will now insert the default Huffman tables. In order to save space, many motion JPEG video frames are encoded without the default Huffman tables, so these frames can now be successfully decompressed by libjpeg-turbo without additional work on the part of the application. An application can still override the Huffman tables, for instance to re-use tables from a previous frame of the same video. [5] The Huffman encoder now uses clz and bsr instructions for bit counting on ARM platforms rather than a lookup table. This reduces the memory footprint by 64k, which may be important for some mobile applications. Out of four Android devices that were tested, two demonstrated a small overall performance loss (~3-4% on average) with ARMv6 code and a small gain (also ~3-4%) with ARMv7 code when enabling this new feature, but the other two devices demonstrated a significant overall performance gain with both ARMv6 and ARMv7 code (~10-20%) when enabling the feature. Actual mileage may vary. [7] Improved the accuracy and performance of the non-SIMD implementation of the floating point inverse DCT (using code borrowed from libjpeg v8a and later.) The accuracy of this implementation now matches the accuracy of the SSE/SSE2 implementation. Note, however, that the floating point DCT/IDCT algorithms are mainly a legacy feature. They generally do not produce significantly better accuracy than the slow integer DCT/IDCT algorithms, and they are quite a bit slower. [8] Added a new output colorspace (JCS_RGB565) to the libjpeg API that allows for decompressing JPEG images into RGB565 (16-bit) pixels. If dithering is not used, then this code path is SIMD-accelerated on ARM platforms. [13] Restored 12-bit-per-component JPEG support. A 12-bit version of libjpeg-turbo can now be built by passing an argument of --with-12bit to configure (Unix) or -DWITH_12BIT=1 to cmake (Windows.) 12-bit JPEG support is included only for convenience. Enabling this feature disables all of the performance features in libjpeg-turbo, as well as arithmetic coding and the TurboJPEG API. The resulting library still contains the other libjpeg-turbo features (such as the colorspace extensions), but in general, it performs no faster than libjpeg v6b. [14] Added ARM 64-bit SIMD acceleration for the YCC-to-RGB color conversion and IDCT algorithms (both are used during JPEG decompression.) For unknown reasons (probably related to clang), this code cannot currently be compiled for iOS. [15] Fixed an extremely rare bug that could cause the Huffman encoder's local buffer to overrun when a very high-frequency MCU is compressed using quality 100 and no subsampling, and when the JPEG output buffer is being dynamically resized by the destination manager. This issue was so rare that, even with a test program specifically designed to make the bug occur (by injecting random high-frequency YUV data into the compressor), it was reproducible only once in about every 25 million iterations. [16] Fixed an oversight in the TurboJPEG C wrapper: if any of the JPEG compression functions was called repeatedly with the same automatically-allocated destination buffer, then TurboJPEG would erroneously assume that the jpegSize parameter was equal to the size of the buffer, when in fact that parameter was probably equal to the size of the most recently compressed JPEG image. If the size of the previous JPEG image was not as large as the current JPEG image, then TurboJPEG would unnecessarily reallocate the destination buffer. 1.3.1 ===== [3] Fixed a bug whereby attempting to encode a progressive JPEG with arithmetic entropy coding (by passing arguments of -progressive -arithmetic to cjpeg or jpegtran, for instance) would result in an error, "Requested feature was omitted at compile time". [4] Fixed a couple of issues whereby malformed JPEG images would cause libjpeg-turbo to use uninitialized memory during decompression. [5] Fixed an error ("Buffer passed to JPEG library is too small") 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. @ text @d1 1 a1 1 $NetBSD: patch-aa,v 1.2 2013/08/21 15:24:00 richard Exp $ d3 1 a3 1 --- Makefile.in.orig 2015-01-07 04:56:55.000000000 +0000 d5 9 a13 1 @@@@ -494,11 +494,11 @@@@ dist_man1_MANS = cjpeg.1 djpeg.1 jpegtra a16 1 -docdir = $(datadir)/doc a20 5 -exampledir = $(datadir)/doc +exampledir = $(datadir)/doc/libjpeg-turbo dist_example_DATA = example.c EXTRA_DIST = win release $(DOCS) testimages CMakeLists.txt \ sharedlib/CMakeLists.txt cmakescripts libjpeg.map.in doc doxygen.config \ @ 1.2 log @1.3.0 ===== [1] 'make test' now works properly on FreeBSD, and it no longer requires the md5sum executable to be present on other Un*x platforms. [2] Overhauled the packaging system: -- To avoid conflict with vendor-supplied libjpeg-turbo packages, the official RPMs and DEBs for libjpeg-turbo have been renamed to "libjpeg-turbo-official". -- The TurboJPEG libraries are now located under /opt/libjpeg-turbo in the official Linux and Mac packages, to avoid conflict with vendor-supplied packages and also to streamline the packaging system. -- Release packages are now created with the directory structure defined by the configure variables "prefix", "bindir", "libdir", etc. (Un*x) or by the CMAKE_INSTALL_PREFIX variable (Windows.) The exception is that the docs are always located under the system default documentation directory on Un*x and Mac systems, and on Windows, the TurboJPEG DLL is always located in the Windows system directory. -- To avoid confusion, official libjpeg-turbo packages on Linux/Unix platforms (except for Mac) will always install the 32-bit libraries in /opt/libjpeg-turbo/lib32 and the 64-bit libraries in /opt/libjpeg-turbo/lib64. -- Fixed an issue whereby, in some cases, the libjpeg-turbo executables on Un*x systems were not properly linking with the shared libraries installed by the same package. -- Fixed an issue whereby building the "installer" target on Windows when WITH_JAVA=1 would fail if the TurboJPEG JAR had not been previously built. -- Building the "install" target on Windows now installs files into the same places that the installer does.
