The vulnerability allows a remote attacker to cause DoS condition on the target system.

The weakness exists due to buffer overflow in the RTSP Packet Handler. A remote attacker can send a specially crafted packet using the Range parameter of the RTSP transaction, trigger memory corruption and cause the service to crash.

Successful exploitation of the vulnerability results in denial of service.
