CVE-2017-12434

In ImageMagick 7.0.6-1, a missing NULL check vulnerability was found in the function ReadMATImage in coders/mat.c, which allows attackers to cause a denial of service (assertion failure) in DestroyImageInfo in image.c.

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.

This update for ImageMagick fixes several issues.
