Synopsis
=======

xli and xloadimage are vulnerable to multiple issues, potentially leading to the execution of arbitrary code.



Background
=========

xli and xloadimage are X11 utilities for displaying and manipulating a wide range of image formats.

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

-------------------------------------------------------------------
Package / Vulnerable / Unaffected
-------------------------------------------------------------------
1 media-gfx/xloadimage < 4.1-r2 >= 4.1-r2
2 media-gfx/xli < 1.17.0-r1 >= 1.17.0-r1
-------------------------------------------------------------------
2 affected packages on all of their supported architectures.
-------------------------------------------------------------------

Description
==========

Tavis Ormandy of the Gentoo Linux Security Audit Team has reported that xli and xloadimage contain a flaw in the handling of compressed images, where shell meta-characters are not adequately escaped. Rob Holland of the Gentoo Linux Security Audit Team has reported that an xloadimage vulnerability in the handling of Faces Project images discovered by zen-parse in 2001 remained unpatched in xli. Additionally, it has been reported that insufficient validation of image properties in xli could potentially result in buffer management errors.

Impact
=====

Successful exploitation would permit a remote attacker to execute arbitrary shell commands, or arbitrary code with the privileges of the xloadimage or xli user.

Workaround
=========

There is no known workaround at this time.

Resolution
=========

All xli users should upgrade to the latest version:

# emerge --sync
# emerge --ask --oneshot --verbose ">=media-gfx/xli-1.17.0-r1"

All xloadimage users should also upgrade to the latest version:

# emerge --sync
# emerge --ask --oneshot --verbose ">=media-gfx/xloadimage-4.1-r2"
