Synopsis
========
GraphicsMagick is vulnerable to a heap overflow when decoding Photoshop
Document (PSD) files, which could lead to arbitrary code execution.
Background
==========
GraphicsMagick is a collection of tools to read, write and manipulate
images in many formats. GraphicsMagick is originally derived from
ImageMagick 5.5.2.
Affected packages
=================
-------------------------------------------------------------------
Package / Vulnerable / Unaffected
-------------------------------------------------------------------
1 media-gfx/graphicsmagick < 1.1.5 >= 1.1.5
Description
===========
Andrei Nigmatulin discovered that handling a Photoshop Document (PSD)
file with more than 24 layers in ImageMagick could trigger a heap
overflow (GLSA 200501-26). GraphicsMagick is based on the same code and
therefore suffers from the same flaw.
Impact
======
An attacker could potentially design a malicious PSD image file to
cause arbitrary code execution with the permissions of the user running
GraphicsMagick.
Workaround
==========
There is no known workaround at this time.
Resolution
==========
All GraphicsMagick users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose ">=media-gfx/graphicsmagick-1.1.5"
