This signature detects attempts to exploit a known vulnerability against Real Networks Real Server. Windows and Linux versions of Real Server are vulnerable. Attackers can send an abnormally long RTSP DESCRIBE request to cause a server overflow and possibly execute arbitrary code.
Helix Universal Server is a multiple type media server distributed and maintained by RealNetworks. It is available for Unix, Linux, and Microsoft Windows platforms. A buffer overflow has been reported in the Helix Universal Server. Due to insufficient bounds checking on the 'describe' field of a RTSP request, it is possible for a user to exploit a boundry condition error. This could lead to the remote execution of arbitrary code with the privileges of the Helix Universal Server process.
