Summary

A vulnerability in Locator/ID Separation Protocol (LISP) control message 
processing in Cisco IOS Software and Cisco IOS XE Software could allow an 
unauthenticated, remote attacker to cause a vulnerable device to disable Cisco 
Express Forwarding and eventually drop traffic passing through.

The vulnerability is due to insufficient checking of certain parameters in LISP
control messages on the Ingress Tunnel Router (ITR). An attacker could exploit 
this vulnerability by sending malformed LISP control messages to the ITR. An 
exploit could allow the attacker to cause a vulnerable device to disable Cisco 
Express Forwarding and eventually drop traffic passing through.
