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"
