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"
