Updated ImageMagick packages that fix a security flaw are now available for Red Hat Enterprise Linux 4. This update has been rated as having moderate security impact by the Red Hat Security Response Team.
ImageMagick is an image display and manipulation tool for the X Window System. Andrei Nigmatulin discovered a heap based buffer overflow flaw in the ImageMagick image handler. An attacker could create a carefully crafted Photoshop Document (PSD) image in such a way that it would cause ImageMagick to execute arbitrary code when processing the image. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CAN-2005-0005 to this issue. Users of ImageMagick should upgrade to these updated packages, which contain a backported patch, and are not vulnerable to this issue.
