Synopsis
========

xv contains a format string vulnerability, potentially resulting in the
execution of arbitrary code.

Background
==========

xv is an interactive image manipulation package for X11.

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

-------------------------------------------------------------------
Package / Vulnerable / Unaffected
-------------------------------------------------------------------
1 media-gfx/xv < 3.10a-r10 >= 3.10a-r10

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

Tavis Ormandy of the Gentoo Linux Security Audit Team identified a flaw
in the handling of image filenames by xv.

Impact
======

Successful exploitation would require a victim to process a specially
crafted image with a malformed filename, potentially resulting in the
execution of arbitrary code.

Workaround
==========

There is no known workaround at this time.

Resolution
==========

All xv users should upgrade to the latest version:

# emerge --sync
# emerge --ask --oneshot --verbose ">=media-gfx/xv-3.10a-r10"
