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
