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"
