CVE-2017-12983

Heap-based buffer overflow in the ReadSFWImage function in coders/sfw.c in ImageMagick 7.0.6-8 allows remote attackers to cause a denial of service (application crash) or possibly have unspecified other impact via a crafted file.

The imagemagick package has been updated to version 6.9.9.41 which fixes several unspecified security vulnerabilities. This update fixes several vulnerabilities in imagemagick, including: Various memory handling problems and cases of missing or incomplete input sanitising may result in denial of service, memory disclosure or the execution of arbitrary code if malformed GIF, TTF, SVG, TIFF, PCX, JPG or SFW files are processed.

Several packages have been rebuilt for the updated ImageMagick.

• CVE-2017-14165: The ReadSUNImage function in coders/sun.c has an issue where memory allocation is excessive because it depends only on a length field in a header. This may lead to remote denial of service in the MagickMalloc function in magick/memory.c. [bsc#1057508]
• CVE-2017-12587: Large loop vulnerability in the ReadPWPImage function in coders\pwp.c. [bsc#1052450]

It was discovered that ImageMagick incorrectly handled certain malformed image files. If a user or automated system using ImageMagick were tricked into opening a specially crafted image, an attacker could exploit this to cause a denial of service or possibly execute code with the privileges of the user invoking the program.
