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"
