FreeBSD : mplayer -- buffer overflow in the code for RealMedia RTSP streams. (b2ff68b2-9f29-11db-a4e4-0211d87675b7)

Synopsis :

The remote FreeBSD host is missing one or more security-related
updates.

Description :

A potential buffer overflow was found in the code used to handle
RealMedia RTSP streams. When checking for matching asm rules, the code
stores the results in a fixed-size array, but no boundary checks are
performed. This may lead to a buffer overflow if the user is tricked
into connecting to a malicious server. Since the attacker can not
write arbitrary data into the buffer, creating an exploit is very
hard; but a DoS attack is easily made. A fix for this problem was
committed to SVN on Sun Dec 31 13:27:53 2006 UTC as r21799. The fix
involves three files: stream/realrtsp/asmrp.c, stream/realrtsp/asmrp.h
and stream/realrtsp/real.c.
