3. Problem description:

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

Several security flaws were discovered in the way ImageMagick decodes DCM, PALM, and SGI graphic files. An attacker may be able to execute arbitrary code on a victim's machine if they were able to trick the victim into opening a specially crafted image file (CVE-2006-5456, CVE-2006-5868).

A heap overflow flaw was found in ImageMagick. An attacker may be able to execute arbitrary code on a victim's machine if they were able to trick the victim into opening a specially crafted file (CVE-2006-2440). This issue only affected the version of ImageMagick distributed with Red Hat Enterprise Linux 4.

Users of ImageMagick should upgrade to these updated packages, which contain backported patches to correct these issues.

4. Solution:

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

This update is available via Red Hat Network. To use Red Hat Network, launch the Red Hat Update Agent with the following command:

up2date

This will start an interactive process that will result in the appropriate RPMs being upgraded on your system.
