Description

Background

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

Description

Andrei Nigmatulin discovered that a Photoshop Document (PSD) file with more than 24 layers could trigger a heap overflow.

Impact

An attacker could potentially design a mailicous PSD image file 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-6.1.8.8"
