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"
