Summary
=======

A vulnerability in Cisco TelePresence Server devices running software versions 3.0 
through 4.2(4.18) could allow an unauthenticated, remote attacker to cause a kernel 
panic on the device.

The vulnerability exists due to a failure to properly handle a specially crafted stream 
of IPv6 packets. A successful exploit could allow an attacker to cause a kernel panic,
