A security issue affects these releases of Ubuntu and its derivatives:

• Ubuntu 13.10
• Ubuntu 12.10
• Ubuntu 12.04 LTS

Summary

ImageMagick could be made to crash or run programs if it opened a specially crafted image file.

Software Description

• imagemagick - Image manipulation programs and library

Details

Aleksis Kauppinen, Joonas Kuorilehto and Tuomas Parttimaa discovered that ImageMagick incorrectly handled certain restart markers in JPEG images. If a user or automated system using ImageMagick were tricked into opening a specially crafted JPEG image, an attacker could exploit this to cause memory consumption, resulting in a denial of service. This issue only affected Ubuntu 12.04 LTS. (CVE-2012-0260)

It was discovered that ImageMagick incorrectly handled decoding certain PSD images. If a user or automated system using ImageMagick were tricked into opening a specially crafted PSD 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. (CVE-2014-1958, CVE-2014-2030)
