Security Advisory

1) Denial of service


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

The weakness exists in the implementation of the H.264 protocol in Cisco Meeting Server (CMS) due to improper validation of Fragmentation Unit (FU-A) protocol packets. A remote attacker can send a specially crafted H.264 FU-A packet through the affected application and trigger an unexpected restart of the CMS media process.

Successful exploitation of the vulnerability results in denial of service.
