Synopsis
=3D=3D=3D=3D=3D=3D=3D=3D

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
=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D

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

Affected packages
=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3 D

-------------------------------------------------------------------
Package / Vulnerable / Unaffected
-------------------------------------------------------------------
1 media-video/kaffeine < 0.5_rc1-r1 >=3D 0.5_rc1-r1
*>=3D 0.4.3b-r1
2 media-video/gxine < 0.3.3-r1 >=3D 0.3.3-r1
-------------------------------------------------------------------
2 affected packages on all of their supported architectures.
-------------------------------------------------------------------

Description
=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D

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
=3D=3D=3D=3D=3D=3D

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
=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D

There is no known workaround at this time.

Resolution
=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D

All Kaffeine users should upgrade to the latest version:

# emerge --sync
# emerge --ask --oneshot --verbose ">=3Dmedia-video/kaffeine-0.4.3b-r1"

All gxine users should upgrade to the latest version:

# emerge --sync
# emerge --ask --oneshot --verbose ">=3Dmedia-video/gxine-0.3.3-r1"
