http://security.gentoo.org/

Severity:	normal
Title:	ImageMagick: User-assisted execution of arbitrary code
Date:	03/06/2012
Bugs:	#402999
ID:	201203-09

Synopsis

Vulnerabilities found in ImageMagick might allow remote attackers to execute arbitrary code.

Background

ImageMagick is a collection of tools and libraries for manipulating various image formats.

Affected packages

Package	Vulnerable	Unaffected	Architecture(s)
media-gfx/imagemagick	< 6.7.5.3	>= 6.7.5.3	All supported architectures

Description

Two vulnerabilities have been found in ImageMagick:

Incorrect offset and count values in the ResolutionUnit tag in EXIF IFD could cause memory corruption (CVE-2012-0247).
IOP tag offsets pointing to the beginning of an IFD could cause an infinite loop of ImageMagick parsing the IFD structure (CVE-2012-0248).

Impact

A remote attacker could entice a user to open a specially crafted image, possibly resulting in execution of arbitrary code or a Denial of Service condition.

Workaround

There is no known workaround at this time.

Resolution

All ImageMagick users should upgrade to the latest version:

      # emerge --sync
      # emerge --ask --oneshot --verbose ">=media-gfx/imagemagick-6.7.5.3"
