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"
