CVE-2017-16546

The ReadWPGImage function in coders/wpg.c in ImageMagick 7.0.7-9 does not properly validate the colormap index in a WPG palette, which allows remote attackers to cause a denial of service (use of uninitialized data or invalid memory allocation) or possibly have unspecified other impact via a malformed WPG 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-2017-12587: 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.
