Cisco has acknowledged some vulnerabilities in Cisco PIX and ASA appliances, which can be exploited by malicious people to cause a DoS (Denial of Service).

1) An unspecified error exists within the handling of Transport Layer Security (TLS) packets. This can be exploited to reload an affected device by sending specially crafted TLS packets.

2) An unspecified error exists within the handling of Media Gateway Control Protocol (MGCP) packets. This can be exploited to reload an affected device by sending specially crafted MGCP packets.

Successful exploitation of this vulnerability requires that the MGCP application layer protocol inspection is enabled (disabled by default).
