Synopsis
========

Multiple buffer overflows have been discovered in ImageMagick, which
could potentially result in the execution of arbitrary code.

Background
==========

ImageMagick is a free software suite to manipulate, convert, and create
many image formats.

Affected packages
=================

    -------------------------------------------------------------------
     Package                /  Vulnerable  /                Unaffected
    -------------------------------------------------------------------
  1  media-gfx/imagemagick      < 6.2.9.5                   >= 6.2.9.5

Description
===========

Tavis Ormandy of the Google Security Team discovered a stack and heap
buffer overflow in the GIMP XCF Image decoder and multiple heap and
integer overflows in the SUN bitmap decoder. Damian Put discovered a
heap overflow in the SGI image decoder.

Impact
======

An attacker may be able to create a specially crafted image that, when
processed with ImageMagick, executes arbitrary code with the privileges
of the executing user.

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-6.2.9.5"
