Synopsis

Moderate: ImageMagick security update

Type/Severity

Security Advisory: Moderate

Topic

Updated ImageMagick packages that correct several security issues are now
available for Red Hat Enterprise Linux version 2.1.

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 heap-based buffer overflow flaws were found in ImageMagick. If a
victim opened a specially-crafted DCM or XWD file, an attacker could
potentially execute arbitrary code on the victim's machine. (CVE-2007-1797)

Several denial of service flaws were found in ImageMagick's parsing of XCF
and DCM files. Attempting to process a specially crafted input file in
these formats could cause ImageMagick to enter an infinite loop.
(CVE-2007-4985)

Several integer overflow flaws were found in ImageMagick. If a victim
opened a specially-crafted DCM, DIB, XBM, XCF or XWD file, an attacker
could potentially execute arbitrary code with the privileges of the user
running ImageMagick. (CVE-2007-4986)

A heap-based buffer overflow flaw was found in ImageMagick's processing of
certain malformed PCX images. If a victim opened a specially-crafted PCX
file, an attacker could possibly execute arbitrary code with the privileges
of the user running ImageMagick.. (CVE-2008-1097)

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