Synopsis
========

ImageMagick contains an error in boundary checks when handling EXIF
information, which could lead to arbitrary code execution.

Background
==========

ImageMagick is a collection of tools to read, write and manipulate
images in many formats.

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

    -------------------------------------------------------------------
     Package                /  Vulnerable  /                Unaffected
    -------------------------------------------------------------------
  1  media-gfx/imagemagick      < 6.1.3.2                   >= 6.1.3.2

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

ImageMagick fails to do proper bounds checking when handling image
files with EXIF information.

Impact
======

An attacker could use an image file with specially-crafted EXIF
information to cause arbitrary code execution with the permissions of
the user running ImageMagick.

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-6.1.3.2"
