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

-------------------------------------------------------------------

1 media-gfx/imagemagick < 6.7.5.3 >= 6.7.5.3

 

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"
