RHSA-2007:0015 - Security Advisory

Topic

Updated ImageMagick packages that correct several security issues are now
available.

This update has been rated as having moderate security impact by the Red
Hat Security Response Team.

Description

ImageMagick is an image display and manipulation tool for the X Window
System that can read and write multiple image formats.

Several security flaws were discovered in the way ImageMagick decodes DCM,
PALM, and SGI graphic files. An attacker may be able to execute arbitrary
code on a victim's machine if they were able to trick the victim into
opening a specially crafted image file (CVE-2006-5456, CVE-2006-5868).

A heap overflow flaw was found in ImageMagick. An attacker may be able to
execute arbitrary code on a victim's machine if they were able to trick the
victim into opening a specially crafted file (CVE-2006-2440). This issue
only affected the version of ImageMagick distributed with Red Hat
Enterprise Linux 4.

Users of ImageMagick should upgrade to these updated packages, which
contain backported patches to correct these issues.
