CVE-2016-8677

The AcquireQuantumPixels function in MagickCore/quantum.c in ImageMagick before 7.0.3-1 allows remote attackers to have unspecified impact via a crafted image file, which triggers a memory allocation failure.

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 the following issues:

These vulnerabilities could be triggered by processing specially crafted image files, which could lead to a process crash or resource consumtion, or potentially have unspecified futher impact.

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.
