Synopsis
========

Kaffeine and gxine both contain a buffer overflow that can be exploited when accessing content from a malicious HTTP server with specially crafted headers.



Background
==========

Kaffeine and gxine are graphical front-ends for xine-lib multimedia library.

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

-------------------------------------------------------------------
Package / Vulnerable / Unaffected
-------------------------------------------------------------------
1 media-video/kaffeine < 0.5_rc1-r1 >= 0.5_rc1-r1
*>= 0.4.3b-r1
2 media-video/gxine < 0.3.3-r1 >= 0.3.3-r1
-------------------------------------------------------------------
2 affected packages on all of their supported architectures.
-------------------------------------------------------------------

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

KF of Secure Network Operations has discovered an overflow that occurs during the Content-Type header processing of Kaffeine. The vulnerable code in Kaffeine is reused from gxine, making gxine vulnerable as well.

Impact
======

An attacker could create a specially-crafted Content-type header from a malicious HTTP server, and crash a user's instance of Kaffeine or gxine, potentially allowing the execution of arbitrary code.

Workaround
==========

There is no known workaround at this time.

Resolution
==========

All Kaffeine users should upgrade to the latest version:

# emerge --sync
# emerge --ask --oneshot --verbose ">=media-video/kaffeine-0.4.3b-r1"

All gxine users should upgrade to the latest version:

# emerge --sync
# emerge --ask --oneshot --verbose ">=media-video/gxine-0.3.3-r1"
