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)
