ImageMagick security update
Security Advisory: Moderate
Updated ImageMagick packages that fix a format string bug 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(TM) is an image display and manipulation tool for the X Window
System which can read and write multiple image formats.
A format string bug was found in the way ImageMagick handles filenames. An
attacker could execute arbitrary code on a victim's machine if they were
able to trick the victim into opening a file with a specially crafted name.
The Common Vulnerabilities and Exposures project (cve.mitre.org) has
assigned the name CAN-2005-0397 to this issue.
Additionally, a bug was fixed which caused ImageMagick(TM) to occasionally
segfault when writing TIFF images to standard output.
Users of ImageMagick should upgrade to these updated packages, which
contain a backported patch, and are not vulnerable to these issues.
Before applying this update, make sure that all previously-released
errata relevant to your system have been applied. Use Red Hat
