Summary

A vulnerability in the Network-Based Application Recognition (NBAR) protocol 
process of the Cisco 2900 Series Integrated Services Router could allow an 
unauthenticated, remote attacker to cause a denial of service (DoS) condition.

The vulnerability occurs when the NBAR process locks. An attacker could 
exploit this vulnerability by sending simple IP version 4 (IPv4) packets 
through the router. An exploit could allow the attacker to cause a DoS 
condition that would require a router restart.

these issues should contact their normal support channels. Free software
