"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).

Note that Tenable Network Security has extracted the preceding
description block directly from the Ubuntu security advisory. Tenable
has attempted to automatically clean and format it as much as possible
without introducing additional issues."
