Description

 Real Networks Helix Universal Server and RealServer contain a flaw that may allow a remote attacker to execute arbitrary code. The issue is due to a flaw in the RTSP DESCRIBE request handling that doesn't properly sanitize user input. If an attacker sends a specially crafted RTSP DESCRIBE request with an overly long URL they may be able to overflow a buffer and execute arbitrary code with the same privilege as the server.
