Description: A buffer overflow vulnerability was reported in Kaffeine. A remote user can cause a target user's media player to crash.
KF of Secure Network Operations reported that a remote user can create a specially crafted RealAudio 'ram' playlist that, when loaded
by the target user, will trigger a buffer overflow within the Kaffeine player. The overflow resides in the processing of Content-Type
headers in the http_open() function in 'http.c'.
The file can cause the target user's player to crash. It may be possible to
execute arbitrary code, but that was not confirmed in the report.
The vendor has been notified without response.
|
Impact: A remote user can cause the target user's player to crash.
|
Solution: Gentoo has released a fix and indicates that all Kaffeine users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose ">=media-video/kaffeine-0.4.3b-r1"

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=3D
-------------------------------------------------------------------
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"
