ImageMagick(TM) is an image display and manipulation tool for the X Window System that can read and write multiple image formats.
A denial of service bug was found in the way ImageMagick parses XWD files. A user or program executing ImageMagick to process a malicious XWD file can cause ImageMagick to enter an infinite loop causing a denial of service condition. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CAN-2005-1739 to this issue.
Users of ImageMagick should upgrade to these updated packages, which contain a backported patch, and are not vulnerable to this issue.
