Description:
Microsoft Internet Security and Acceleration Server 2000 contain a vulnerability in the H.323 protocol implementation, which can be exploited by malicious people to cause a DoS (Denial of Service) or gain system access.
The vulnerability is caused due to various errors in the processing of H.323 traffic over TCP, which allows malicious people to overflow a buffer. This can be exploited by sending specially crafted messages to an affected system (default port 1720/tcp).
Successful exploitation may allow a malicious person to execute arbitrary code or crash a vulnerable system.
The H.323 filter is enabled by default on systems running in integrated or firewall mode.
