Synopsis
========

A format string vulnerability exists in ImageMagick that may allow an
attacker to execute arbitrary code.

Background
==========

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

Affected packages
=================

    -------------------------------------------------------------------
     Package                /  Vulnerable  /                Unaffected

Description
===========

Tavis Ormandy of the Gentoo Linux Security Audit Team has identified a
flaw in the handling of filenames by the ImageMagick utilities.

Impact
======

Successful exploitation may disrupt web applications that depend on
ImageMagick for image processing, potentially executing arbitrary code.

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-6.2.0.4"
