Date: Sun, 10 Dec 2017 11:32:31 -0600 (CST) From: Bob Friesenhahn <bfriesen@...ple.dallas.tx.us> To: oss-security@...ts.openwall.com Subject: GraphicsMagick 1.3.27 is available [ This release announcement is forwarded to the oss-security list due the many security issues found in 1.3.26 and fixed by 1.3.27. Much thanks to the security researchers and OS package maintainers who notified us about problems and sometimes provided useful analysis and patches.] GraphicsMagick 1.3.27 (the 61st release, and the 28th in this cycle) is now available. This release is API and ABI compatible with previous 1.3.X releases so it is possible to update without re-compiling dependent programs. There have been a large number of security issues and other stability bugs fixed in this release. There has been intense fuzzing activity and code inspections by a number of people, resulting in many issues identified and fixed. It is recommended to update to this release immediately. The SHA1 checksums for the release files are as follows: ed18c3db2ad786453ebe495222b24acdb8374a6d GraphicsMagick-1.3.27-1.src.rpm ec9f366a22053ddeb14373bc3abdbe5843626c62 GraphicsMagick-1.3.27-Q16-win32-dll.exe 79cfc2774e4c259e7953a08c2148eb8aa5297b78 GraphicsMagick-1.3.27-Q16-win64-dll.exe 91cf1930279a033d65f11ce54fea05cde0d75d3b GraphicsMagick-1.3.27-Q8-win32-dll.exe 20dbbaebbc6df485d02e5fd687dfbe72fe30ec37 GraphicsMagick-1.3.27-Q8-win64-dll.exe 4c3676e3dcf36d3bc3538729316bb3dbdccff28f GraphicsMagick-1.3.27-windows-source.7z cb8fc4751c159c52913af7f0f9b572486c2efd4b GraphicsMagick-1.3.27.tar.bz2 ca58a6004012a17e8fee587125b5bb3e314e8b3d GraphicsMagick-1.3.27.tar.gz 863d359c7ee2a4f074e1f543ad97c4d2c01d64bb GraphicsMagick-1.3.27.tar.lz f334cfc6f03e6d4dfea8d9fe0643820649d20f7a GraphicsMagick-1.3.27.tar.xz The news for this release follows: Special Issues: * None Security Fixes: * CMYK: Fix heap overwrites in raw CMYK writer. Fix heap overwrites in raw CMYK reader (noticed when doing montage). * GIF: Assure that global colormap is initialized. * DescribeImage(): Fix possible heap write overflow when describing visual image directory. Fix possible heap read overflow while accessing heap data, and possible information disclosure while describing the IPTC profile. * DICOM: Fix huge memory allocation based on bogus length value (DOS opportunity). * DrawDashPolygon(): Fix heap out of bounds read in render code. * GRAY: Fix heap overwrites in raw GRAY reader (noticed when doing montage). * JNG: Fix heap overruns. Fix assertions. * JNG: Prevent a crash due to zero-length color_image while reading a JNG image. (CVE-2017-11102). Reject JNG files with unreasonable dimensions given the file size (avoid DOS). * JNX: Fix DOS due to excessive memory allocations with corrupt file. * JPEG: Do not allocate backing image pixels until a scanline has been successfully read. Avoids DOS opportunity with suitably manufactured file. * MAP: Fix null pointer dereference or segmentation violation. * MAT: Fix heap write overflow. * MNG: Reject over-large (65k by 65k) image. Fix heap overwrites. * PAM: Fix heap buffer overflow in PAM writer for 1 bit/sample + alpha. * PICT: Fix excessive memory allocation due to malformed image file. * PNG: Fix heap buffer overflow in PNG writer when promoting from indexed PNG to RGBA. * PNM: Fix DOS due to excessive memory allocations with corrupt file. * RGB: Fix heap overwrite in raw RGB writer. Fix heap overwrites in raw RGB reader (noticed when doing montage). * RLE: Fix DOS opportunities due to false claims in image header. Fix heap out of bounds read. * SFW: Avoid possible heap write overflow. * SUN: Fix heap read overflow. Fix DOS due to excessive memory allocations with corrupt file. * SVG: Fix heap write overflow. * TIFF: Use heuristics to avoid DOS (excessive memory use) due to false claims by input file. It is possible that this may reject some valid files. Fix possible small heap overwrite beyond the allocated scanline buffer due to the NumberOfObjectsInArray() macro rounding up rather than down. * UIL: Fix heap overwrite in writer. * WPG: Fix DOS issues (memory, disk space, CPU time) due to insufficient validations. Fix heap overwrites. * XBM: Fix DOS issue where code remains stuck in loop and does not return. * XV 332 (PNM): Fix null pointer dereference due to malformed file. * TracePSClippingPath()/TraceSVGClippingPath(): Fix heap out of bounds read. * Validate path entries in the MAGICK_CODER_MODULE_PATH and MAGICK_FILTER_MODULE_PATH environment variables and convert all paths to real paths if possible. This avoids possible use of relative paths to load modules (a possible security issue), or the possibility of adding a directory which was in the path, but missing, and may improve efficiency by removing non-existent paths. Bug fixes: * AVS: Memory leaks eliminated. * CINEON: Fix possible use of NULL pointer. * CMYK: Memory leaks eliminated. * CUT: Memory leaks eliminated. Fix possible use of NULL pointer. * DCM: Fix possible use of NULL pointer. * DrawImage(): Avoid "negative" strncpy(). This seems to be benign with glibc but perhaps not with other implementations. * DPX: Memory leaks eliminated. * EMF: Fix possible use of NULL pointer. * FindMagickModule(): Fix possible use of NULL pointer. * FITS: Fix memory leak. * GIF: Fix memory leak. * HDF: Memory leaks eliminated. * HISTOGRAM: Fix memory leak. * JNG: Memory leaks eliminated. Memory use after free and double-free issues eliminated. Error reporting fixes. * Magick::Options::strokeDashArray(): Fix possible use of NULL pointer. * MagickXFileBrowserWidget(): Fix possible use of NULL pointer. * MAT: Memory leaks eliminated. * MagickMapCloneMap(): Fix possible assertion failure. * MNG: Memory use after free issues eliminated. Fix possible use of NULL pointer. Fix memory leaks. * MontageImageCommand(): Fix memory leaks. * MPC: Fix memory leak in writer. * MPEG: Fix memory leaks in writer. * MTV: Memory leaks eliminated. * NTRegistryKeyLookup(): Fix possible use of NULL pointer. * NTGetTypeList(): Fix possible use of NULL pointer. * PCD: Memory leaks eliminated. * PCL: Fix null pointer dereference in PCL writer. * PCX: Memory leaks eliminated. * PALM: Fix possible use of NULL pointer. Fix memory leak. * PICT: Memory leaks eliminated. * PNG: Fix small (one-off) heap read overflow. * PNM: Fix memory leaks. * PS: Fix use of null pointer in error path. * PWP: Fix possible use of null pointer. * ReplaceImageColormap(): Throw an exception rather than assertion if the input image is not colormapped. * RGB: Fix memory leak. * SegmentImage(): Fix possible use of NULL pointer. * SetImageProfile(): Fix possible assertion failure. * SGI: Check for EOF while reading SGI file header. * SUN: Fix memory leak. * TIFF: Fix possible use of NULL pointer. Fix memory leaks in writer. * TIM: Fix memory leak. * TOPOL: Fix possible use of NULL pointer. Fix memory leaks. * VIFF: Fix memory leak. * WEBP: Detect partial write to output file. * WPG: Fix possible use of null pointer. Fix excessive use of disk resources due to insufficient validations. * WriteImage(): Restore use of GetBlobStatus() to test if an I/O error was encountered while writing output file. This assures that I/O failure in writers which do not themselves verify writes is assured to be reported. * WMF: Memory use after free issues eliminated. * YUV: Fix memory leaks. New Features: * PNG: Implemented eXIf chunk support. * WEBP: Add support for EXIF and ICC metadata provided that at least libwebp 0.5.0 is used. * Magick++ Image autoOrient(): New Image method to auto-orient an image so it looks right-side up by default. Feature improvements: * None Windows Delegate Updates/Additions: * Libtiff is updated to libtiff 4.0.9. Build Changes: * JPEG/PNG: The SETJMP_IS_THREAD_SAFE definition is used to determine if setjmp/longjmp are thread safe. If these interfaces are thread safe, then concurrent reads/writes are possible. This definition is false for Solaris but true for Linux. JPEG and PNG will be fully concurrent if this definition is enabled. Behavior Changes: * PALM: PALM writer is disabled. * ThrowLoggedException(): Capture the first exception at ErrorException level or greater, or only capture exception if it is more severe than an already reported exception. * DestroyJNG(): This internal function is now declared static and is removed from shared library or DLL namespace. -- Bob Friesenhahn bfriesen@...ple.dallas.tx.us, http://www.simplesystems.org/users/bfriesen/ GraphicsMagick Maintainer, http://www.GraphicsMagick.org/
