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"
