imagemagick vulnerabilities
============================================================================

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)

Update instructions:

The problem can be corrected by updating your system to the following
package versions:

Ubuntu 13.10:

  libmagickcore5                  8:6.7.7.10-5ubuntu3.1

Ubuntu 12.10:
  libmagick++5                    8:6.7.7.10-2ubuntu4.2
  libmagickcore5                  8:6.7.7.10-2ubuntu4.2

Ubuntu 12.04 LTS:
  libmagick++4                    8:6.6.9.7-5ubuntu3.3
