ImageMagick security update

CentOS Errata and Security Advisory CESA-2012:0544

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)

It was found that ImageMagick utilities tried to load ImageMagick
configuration files from the current working directory. If a user ran an
ImageMagick utility in an attacker-controlled directory containing a
specially-crafted ImageMagick configuration file, it could cause the
utility to execute arbitrary code. (CVE-2010-4167)

An integer overflow flaw was found in the way ImageMagick processed
certain Exif tags with a large components count. An attacker could create
a specially-crafted image file that, when opened by a victim, could cause
ImageMagick to access invalid memory and crash. (CVE-2012-0259)

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)

An out-of-bounds buffer read flaw was found in the way ImageMagick
processed certain TIFF image files. A remote attacker could provide a TIFF
image with a specially-crafted Exif IFD value (the set of tags for
recording Exif-specific attribute information), which once opened by
ImageMagick, would cause it to crash. (CVE-2012-1798)

Red Hat would like to thank CERT-FI for reporting CVE-2012-0259,
CVE-2012-0260, and CVE-2012-1798. CERT-FI acknowledges Aleksis Kauppinen,
Joonas Kuorilehto, Tuomas Parttimaa and Lasse Ylivainio of Codenomicon’s
CROSS project as the original reporters.

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.
