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 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.
