- version update to 1.3.33 * It has been discovered that the 'ICU' library (a perhaps 30MB C++ library) which is now often a libxml2 dependendency causes huge process initialization overhead. This is noticed as unexpected slowness when GraphicsMagick utilities are used to process small to medium sized files. The time to initialize is often longer than the time to read the input file, process the image, and write the output file. If the 'ICU' dependency can not be avoided, then make sure to use the modules build. Please lobby the 'ICU' library developers to change their implementation to avoid long start-up times due to merely linking with the library. * GraphicsMagick is now participating in Google's oss-fuzz project due to the contributions and assistance of Alex Gaynor. Since February 4 2018, 353 issues have been opened by oss-fuzz and 338 of those issues have been resolved. The issues list is available at https://bugs.chromium.org/p/oss-fuzz/issues/list under search term "graphicsmagick". Issues are available for anyone to view and duplicate if they have been in "Verified" status for 30 days, or if they have been in "New" status for 90 days. There are too many fixes to list here. Please consult the GraphicsMagick ChangeLog file, Mercurial repository commit log, and the oss-fuzz issues list for details. * Documentation has been added regarding security hazards due to commands which support a '@filename' syntax. * MontageImages(): Fix wrong length argument to strlcat() when building montage directory, which could allow heap overwrite. * PNG: Pass correct size value to strlcat() in module registration code. This bug is noticed to cause problems for Apple's OS X and Linux Alpine with musl libc. This fixes a regression introduced by the 1.3.32 release.

- version update to 1.3.32 New Features: * Added support for writing the Braille image format (by Samuel Thibault). * WebP writer: Support WebP 'use_sharp_yuv' option ("if needed, use sharp (and slow) RGB->YUV conversion") via -define webp:use-sharp-yuv=true. * The version command output now reports the OpenMP specification number rather than just the integer version identifier. API Updates: * ReallocateImageColormap() added to re-allocate an existing colormap. * Some improperly-exposed globals are now static as they should have been. * The 'benchmark' command now shows 6 digits (microseconds) of elapsed time indication. * The 'time' command now shows 6 digits (microseconds) of elapsed time indication. * The logging facility now shows 6 digits (microseconds) of time resolulution * Dcraw: When QuantumDepth is greater than 8, pass -6 option to dcraw so that it returns a 16-bit/sample image. * Dcraw: If Dcraw supports TIFF format, then request TIFF format in order to be able to acquire more metatdata. * Scale algorithm: Eliminate artifacts when scaling an image with semi-transparent pixels. * Library metrics: The number of shared library relocations and the amount of initialized data has been signficantly reduced by following recommendations from Ulrich Drepper's document How To Write Shared Libraries <https://akkadia.org/drepper/dsohowto.pdf>_. (Security) Bug Fixes:

- update to 1.3.31: Special Issues: * Firmware and operating system updates to address the Spectre vulnerability (and possibly to some extent the Meltdown vulnerability) have substantially penalized GraphicsMagick's OpenMP performance. Performance is reduced even with GCC 7 and 8's improved optimizers. There does not appear to be anything we can do about this.

- update to 1.3.29: * Security Fixes: . GraphicsMagick is now participating in Google's oss-fuzz project . JNG: Require that the embedded JPEG image have the same dimensions as the JNG image as provided by JHDR. Avoids a heap write overflow. . MNG: Arbitrarily limit the number of loops which may be requested by the MNG LOOP chunk to 512 loops, and provide the '-define mng:maximum-loops=value' option in case the user wants to change the limit. This fixes a denial of service caused by large LOOP specifications. * Bug fixes: . DICOM: Pre/post rescale functions are temporarily disabled (until the implementation is fixed). . JPEG: Fix regression in last release in which reading some JPEG files produces the error "Improper call to JPEG library in state 201". . ICON: Some DIB-based Windows ICON files were reported as corrupt to an unexpectedly missing opacity mask image. . In-memory Blob I/O: Don't implicitly increase the allocation size due to seek offsets. . MNG: Detect and handle failure to allocate global PLTE. Fix divide by zero. . DrawGetStrokeDashArray(): Check for failure to allocate memory. . BlobToImage(): Now produces useful exception reports to cover the cases where 'magick' was not set and the file format could not be deduced from its header. * API Updates: . Wand API: Added MagickIsPaletteImage(), MagickIsOpaqueImage(), MagickIsMonochromeImage(), MagickIsGrayImage(), MagickHasColormap() based on contributions by Troy Patteson.

- upate to 1.3.28: * Security Fixes: BMP: Fix non-terminal loop due to unexpected bit-field mask value (DOS opportunity). PALM: Fix heap buffer underflow in builds with QuantumDepth=8. SetNexus() Fix heap overwrite under certain conditions due to using a wrong destination buffer. This issue impacts all 1.3.X releases. TIFF: Fix heap buffer read overflow in LocaleNCompare() when parsing NEWS profile. * Bug fixes: DescribeImage(): Eliminate possible use of null pointer. GIF: Fix memory leak of global colormap in error path. GZ: Writing to gzip files with the extension ".gz" was not working with Zlib 1.2.8. JNG: Fix buffer read overflow (a tiny fixed overflow of just one byte). JPEG: Promoting certain libjpeg warnings to errors caused much more problems than expected. The promotion of warnings to errors is removed. Claimed pixel dimensions are validated by file size before allocating memory for the pixels. IntegralRotateImage(): Assure that reported error in rotate by 270 case does immediately terminate processing. MNG: Fix possible null pointer reference related to DEFI chunk parsing. Fix minor heap read overflow (constrained to just one byte) due to an ordering issue in a limit check. Fix memory leaks in error path. WebP: Fix stack buffer overflow in WriteWEBPImage() which occurs with libwebp 0.5.0 or newer due to a structure type

- update to 1.3.25: * EscapeParenthesis(): I was notified by Gustavo Grieco of a heap overflow in EscapeParenthesis() used in the text annotation code. While not being able to reproduce the issue, the implementation of this function is completely redone. * Utah RLE: Reject truncated/absurd files which caused huge memory allocations and/or consumed huge CPU. Problem was reported by Agostino Sarubbo based on testing with AFL. * SVG/MVG: Fix another case of CVE-2016-2317 (heap buffer overflow) in the MVG rendering code (also impacts SVG). * TIFF: Fix heap buffer read overflow while copying sized TIFF attributes. Problem was reported by Agostino Sarubbo based on testing with AFL.

- updated to 1.3.18: * Due to GCC bug 53967_, several key agorithms (e.g. convolution) may execute much faster (e.g. 2-3X) for x86-64 and/or when SSE is enabled for floating point math (-mfpmath=sse) if the GCC option -frename-registers is used. Default 32-bit builds do not experience the problem since they use '387 math. It is not clear in what version of GCC this problem started but it was not noticed by the developers until the GCC 4.6 timeframe. Other compilers do not suffer from this bug. * Fixed bug with format substitutions if input string ends with a single '%'. * BMP: Fixed an old bug with decoding chromaticity primaries. * PNG: Fixed reading of interlaced images. Fix reading of sub-8-bit palette and grayscale images. Some PNG sub-formats were written incorrectly. Fix crash in PNG8 writer if image colors happened to be non-zero but image was not actually colormapped. * PNG: Configure script now also searches for libpng versions 16 and 17. * TIFF: Fix a crash which was noticed when writing RGBA separated (planar) format. * --enable-symbol-prefix was not prefixing all of the C symbols. Some core C library functions were not prefixed. This option applies to the Wand library API as well now. * C API: When input is from a user-provided file descriptor, the file position is restored after reading the file header bytes. Previously the file position was rewound to the beginning of the file. This allows reading embedded image data from the current offset in a file, and allows continuing to use the stream after GraphicsMagick has returned the image. * C API: It is now possible to invoke CloseBlob() multiple times.

- updated to 1.3.17: * PNG: Fix for CVE-2012-3438. The Magick_png_malloc function in coders/png.c in GraphicsMagick 6.7.8-6 does not use the proper variable type for the allocation size, which might allow remote attackers to cause a denial of service (crash) via a crafted PNG file that triggers incorrect memory allocation. * PNG: Reading sub-8-bit palette images is fixed (images looked stretched). * SVG: Fixed bug which allowed MVG and SVG files with long vector paths to crash the software. * SVG: Ignore XML headers rather than rendering them as text. * MVG/SVG/WMF/-draw: It is now possible to draw a plain ',' character. * etc., see NEWS.txt

- updated to 1.3.16: Security Fixes: * Don't translate 'comment' and 'label' attributes if the request is made while a file is being read. Only translate such attributes if they come from the command line or API user. Bug fixes: * SWT: SWT reader suffered from a number of implementation errors which caused it not to work any more. Works again. * XBM: Fix memory leak observed when reading file in 'ping' mode. * Support -trim on images which use a consistent (single color) transparent background. In this case, trim is done based on opacity rather than foreground color. * Include <sys/types.h> in order to assure that 'size_t' and 'ssize_t' are declared. This is necessary since MagickExtentImage() uses these types as part of its definition. * +repage was not working because parser was insisting that it should include an argument. (i.e. multiplying rather than dividing). * PerlMagick: Fix compilation with Perl 5.16. * PingBlob(): PingBlob was not working for all cases. Is now based on BlobToImage() for assured reliability. Feature improvements: * MAT: Animated movies inside 4D matrices are loaded now. * PDF: File base name is used as the document title. * PNG: Fix issues observed specifically with libpng 1.5.10. Performance Improvements: * Pixel iterators should be more efficient now if the image uses a file-backed cache. * Motion blur algorithm does scale well as cores are added so include OpenMP support for it by default.

- updated to 1.3.15: Bug fixes: * PNG - fixed problem with bit depth when the encoder decides to write RGBA instead of indexed PNG. * Fixed some temporary file leaks which were caused by the temporary file name being automatically extended to include a scene number, and therefore fail to be deleted. New Features: * Added '+noise random' and '-operator noise-random' to 'convert' and 'mogrify'. This modulates the existing image data with uniformely random noise. * Added -strip option in composite, convert, mogrify, and montage to remove all profiles and text attributes from the image. * Added -repage option to composite, convert, mogrify, and montage subcommands to reset or adjust the current image page offsets based on a provided geometry specification. * New C function StripImage() to remove all profiles and text attributes from the image. * New C function ResetImagePage() to adjust the current image page canvas and position based on a relative page specification. * C functions GenerateDifferentialNoise(), AddNoiseImageChannel(), QuantumOperatorRegionImage(), AddNoiseImage() updated to support RandomNoise enumeration. * New C++ Image method strip(), and unary function stripImage() to remove all profiles and text attributes from the image. * XCF format now respects image subimage and subrange members so that returned image layers may be selected. * The INFO coder (e.g. output file "info:-") now respects the -format option so that its output may be adjusted identically to how -format works for 'identify'.
