xv: Filename handling vulnerability

Background

xv is an interactive image manipulation package for X11.

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"
