[GLSA]

Gentoo Linux Security Advisory

Title: ImageMagick: User-assisted execution of arbitrary code (GLSA 201203-09)
Severity: normal
Exploitable: remote
Date: March 06, 2012
Bug(s): #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: media-gfx/imagemagick
Vulnerable: < 6.7.5.3
Unaffected: >= 6.7.5.3
Architectures: 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:
