"Updated ImageMagick packages that fixes a buffer overflow are now
available.

ImageMagick(TM) is an image display and manipulation tool for the X
Window System.

A buffer overflow flaw was discovered in the ImageMagick image
handler. An attacker could create a carefully crafted image file with
an improper EXIF information 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 CVE-2004-0981 to this issue.

David Eisenstein has reported that our previous fix for CVE-2004-0827,
a heap overflow flaw, was incomplete. An attacker could create a
carefully crafted BMP file in such a way that it could cause
ImageMagick to execute arbitrary code when processing the image. The
Common Vulnerabilities and Exposures project (cve.mitre.org) has
assigned the name CVE-2004-0827 to this issue.

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