Moderate: ImageMagick security and bug fix update

Updated ImageMagick packages that fix one security issue and one bug are
now available for Red Hat Enterprise Linux 5.

The Red Hat Security Response Team has rated this update as having moderate
security impact. A Common Vulnerability Scoring System (CVSS) base score,
which gives a detailed severity rating, is available from the CVE link in
the References section.

ImageMagick is an image display and manipulation tool for the X Window
System that can read and write multiple image formats.

An integer overflow flaw, leading to a heap-based buffer overflow, was
found in the ImageMagick routine responsible for creating X11 images. An
attacker could create a specially-crafted image file that, when opened by a
victim, would cause ImageMagick to crash or, potentially, execute arbitrary
code. (CVE-2009-1882)

This update also fixes the following bug:

* previously, portions of certain RGB images on the right side were not
rendered and left black when converting or displaying them. With this
update, RGB images display correctly. (BZ#625058)

Users of ImageMagick are advised to upgrade to these updated packages,
which contain backported patches to correct these issues. All running
instances of ImageMagick must be restarted for this update to take effect.

Before applying this update, make sure all previously-released errata
relevant to your system have been applied.

This update is available via the Red Hat Network. Details on how to
