Kaffeine and gxine are graphical front-ends for xine-lib multimedia library.
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.
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.
There is no known workaround at this time.
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"
