Synopsis
========

xzgv contains multiple overflows that may lead to the execution of
arbitrary code.

Background
==========

xzgv is a picture viewer for X, with a thumbnail-based file selector.

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

    -------------------------------------------------------------------
     Package         /  Vulnerable  /                       Unaffected
    -------------------------------------------------------------------
  1  media-gfx/xzgv       <= 0.8                             >= 0.8-r1

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

Multiple overflows have been found in the image processing code of
xzgv, including an integer overflow in the PRF parsing code
(CAN-2004-0994).

Impact
======

An attacker could entice a user to open or browse a specially-crafted
image file, potentially resulting in the execution of arbitrary code
with the rights of the user running xzgv.

Workaround
==========

There is no known workaround at this time.

Resolution
==========

All xzgv users should upgrade to the latest version:

    # emerge --sync
    # emerge --ask --oneshot --verbose ">=media-gfx/xzgv-0.8-r1"
