Synopsis
========
A vulnerability in ImageMagick allows attackers to crash the
application and potentially execute arbitrary code.
Background
==========
ImageMagick is an application suite to manipulate and convert images.
It is often used as a utility backend by web applications like forums,
content management systems or picture galleries.
Affected packages
=================
-------------------------------------------------------------------
Package / Vulnerable / Unaffected
-------------------------------------------------------------------
1 media-gfx/imagemagick lt; 6.2.5.5 gt;= 6.2.5.5
Description
===========
The SetImageInfo function was found vulnerable to a format string
mishandling. Daniel Kobras discovered that the handling of "%"-escaped
sequences in filenames passed to the function is inadequate. This is a
new vulnerability that is not addressed by GLSA 200503-11.
Impact
======
By feeding specially crafted file names to ImageMagick, an attacker can
crash the program and possibly execute arbitrary code with the
privileges 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 "gt;=media-gfx/imagemagick-6.2.5.5"
