Hello,

 Secunia Research has discovered a vulnerability in Xine, which can be
 exploited by malicious people to compromise a user's system.

 The vulnerability is caused due to a boundary error within the
 "sdpplin_parse()" function in input/libreal/sdpplin.c. This can be
 exploited to overwrite arbitrary memory regions via an overly large
 "streamid" SDP parameter included in a malicious RTSP stream.

 Successful exploitation allows execution of arbitrary code.

 The vulnerability is confirmed in version 1.1.10.1. Other versions may
 also be affected.

 Vulnerability Details:
 ----------------------

 The vulnerability is present in input/libreal/sdpplin.c at line 255.

 ---
 desc->stream[stream->stream_id] = stream;

 Secunia Research has created a PoC for the vulnerability, which is
 available upon request.

 Closing comments:

FWIW, the same vulnerability apply to VLC.

Does VLC know, have a patch? Does xine have a patch?

xine has a patch, the same patch should apply over VLC. I'm not sure if VLC is
informed, I said that to secunia though people though.
