"Tomas Hoger discovered that the GD library did not properly handle the
number of colors in certain malformed GD images. If a user or
automated system were tricked into processing a specially crafted GD
image, an attacker could cause a denial of service or possibly execute
arbitrary code. (CVE-2009-3546)

It was discovered that the GD library did not properly handle
incorrect color indexes. An attacker could send specially crafted
input to applications linked against libgd2 and cause a denial of
service or possibly execute arbitrary code. This issue only affected
Ubuntu 6.06 LTS. (CVE-2009-3293)

It was discovered that the GD library did not properly handle certain
malformed GIF images. If a user or automated system were tricked into
processing a specially crafted GIF image, an attacker could cause a
denial of service. This issue only affected Ubuntu 6.06 LTS.
(CVE-2007-3475, CVE-2007-3476)

It was discovered that the GD library did not properly handle large
angle degree values. An attacker could send specially crafted input to
applications linked against libgd2 and cause a denial of service. This
issue only affected Ubuntu 6.06 LTS. (CVE-2007-3477).

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."
