ImageMagick security update

Updated ImageMagick packages that fix a buffer overflow issue are now
available.

This update has been rated as having important security impact by the Red
Hat Security Response Team.

ImageMagick(TM) is an image display and manipulation tool for the X Window
System which can read and write multiple image formats.

A heap based buffer overflow bug was found in the way ImageMagick parses
PNM files. An attacker could execute arbitrary code on a victim's machine
if they were able to trick the victim into opening a specially crafted PNM
file. The Common Vulnerabilities and Exposures project (cve.mitre.org) has
assigned the name CAN-2005-1275 to this issue.

Users of ImageMagick should upgrade to these updated packages, which
contain a backported patch, and are not vulnerable to this issue.

Before applying this update, make sure that all previously-released
errata relevant to your system have been applied. Use Red Hat
Network to download and update your packages. To launch the Red Hat
