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.
