Cisco Security Advisory - Multiple vulnerabilities exist in the Cisco PGW 2200 Softswitch series of products. Each vulnerability described in this advisory is independent from other. The vulnerabilities are related to processing Session Initiation Protocol (SIP) or Media Gateway Control Protocol (MGCP) messages. Successful exploitation of all but one of these vulnerabilities can crash the affected device. Exploitation of the remaining vulnerability will not crash the affected device, but it can lead to a denial-of-service (DoS) condition in which no new TCP-based connections will be accepted or created.
