Summary

=======

A vulnerability in the Real-Time Transport Protocol (RTP) bitstream
processing of the Cisco Meeting Server could allow an unauthenticated,
remote attacker to cause a denial of service (DoS) condition.

The vulnerability is due to insufficient input validation of incoming
RTP bitstreams. An attacker could exploit this vulnerability by sending
a crafted RTP bitstream to an affected Cisco Meeting Server. A
successful exploit could allow the attacker to deny audio and video
services by causing media process crashes resulting in a DoS condition
on the affected product.

Cisco has released software updates that address this vulnerability.
There are no workarounds that address this vulnerability.
