Cisco products running IOS contain vulnerabilities in the processing of H.323 messages, which are
typically used in packetized voice or multimedia applications. Features such as NAT and IOS
Firewall must inspect H.323 messages and may be vulnerable as well. A test suite has been
developed by the University of Oulu to target this protocol and identify vulnerabilities.

developed by the University of Oulu to target this protocol and identify vulnerabilities.
Support for the H.323 protocol was introduced in Cisco IOS Software Release 11.3T, and all later
Cisco IOS releases are affected if configured for various types of Voice/Multimedia Application
support. The vulnerabilities can be exploited repeatedly to produce a denial of service (DoS).
