Red Hat Security Advisory: ImageMagick security and bug fix update Security Advisory secalert@redhat.com Red Hat Security Response Team RHSA-2012:0545 Final 1 1 2012-05-07T18:14:00Z Current version 2012-05-07T18:14:00Z 2012-05-07T18:14:00Z Red Hat rhsa-to-cvrf 1.0.1478 2012-05-07T18:44:01Z Updated ImageMagick packages that fix three security issues and one bug are now available for Red Hat Enterprise Linux 5. The Red Hat Security Response Team has rated this update as having moderate security impact. Common Vulnerability Scoring System (CVSS) base scores, which give detailed severity ratings, are available for each vulnerability from the CVE links in the References section. ImageMagick is an image display and manipulation tool for the X Window System that can read and write multiple image formats. A flaw was found in the way ImageMagick processed images with malformed Exchangeable image file format (Exif) metadata. An attacker could create a specially-crafted image file that, when opened by a victim, would cause ImageMagick to crash or, potentially, execute arbitrary code. (CVE-2012-0247) A denial of service flaw was found in the way ImageMagick processed images with malformed Exif metadata. An attacker could create a specially-crafted image file that, when opened by a victim, could cause ImageMagick to enter an infinite loop. (CVE-2012-0248) A denial of service flaw was found in the way ImageMagick decoded certain JPEG images. A remote attacker could provide a JPEG image with specially-crafted sequences of RST0 up to RST7 restart markers (used to indicate the input stream to be corrupted), which once processed by ImageMagick, would cause it to consume excessive amounts of memory and CPU time. (CVE-2012-0260) Red Hat would like to thank CERT-FI for reporting CVE-2012-0260. CERT-FI acknowledges Aleksis Kauppinen, Joonas Kuorilehto, Tuomas Parttimaa and Lasse Ylivainio of Codenomicon's CROSS project as the original reporters. This update also fixes the following bug: * The fix for Red Hat Bugzilla bug 694922, provided by the RHSA-2012:0301 ImageMagick update, introduced a regression. Attempting to use the "convert" utility to convert a PostScript document could fail with a "/undefinedfilename" error. With this update, conversion works as expected. (BZ#804546) Users of ImageMagick are advised to upgrade to these updated packages, which contain backported patches to correct these issues. All running instances of ImageMagick must be restarted for this update to take effect. Please see https://www.redhat.com/footer/terms-of-use.html Copyright © 2012 Red Hat, Inc. All rights reserved.
