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 188.8.131.52. Other versions may also be affected.
Solution: Reportedly fixed in version 2.1.10 (2.1 Build 184.108.40.206).
