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

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
