Cisco IOS and Unified Communications Manager Multiple Voice Vulnerabilities

Cisco IOS and Unified Communications Manager are prone to multiple denial-of-service and code-execution vulnerabilities.

These issues pertain to the following protocols or features:

Session Initiation Protocol (SIP)
Media Gateway Control Protocol (MGCP)
Signaling protocols H.323, H.254
Real-time Transport Protocol (RTP)
Facsimile reception

A remote attacker can exploit these issues to execute arbitrary code or cause denial-of-service conditions.
