DESCRIPTION:
Luigi Auriemma has discovered two vulnerabilities in RealWin, which
can be exploited by malicious people to cause a DoS (Denial of
Service) and potentially compromise a vulnerable system.

1) A boundary error when processing "SCPC_INITIALIZE" and
"SCPC_INITIALIZE_RF" packets can be exploited to cause a stack-based
buffer overflow by e.g. sending specially crafted packets to port
912/TCP.

2) A boundary error when processing the "SCPC_TXTEVENT" packets can
be exploited to cause a stack-based buffer overflow by e.g. sending a
specially crafted packet to port 912/TCP.

The vulnerabilities are confirmed in RealWin 2.1 Build 6.1.8.10.
Other versions may also be affected.

SOLUTION:
Restrict network access to trusted users only.
