Summary
=======

The Cisco IOS Software implementation of the network address translation (NAT) feature contains three vulnerabilities 
when translating IP packets that could allow an unauthenticated, remote attacker to cause a denial of service (DoS) 
condition.

Cisco has released free software updates that address these vulnerabilities. Workarounds that mitigate these 
vulnerabilities are not available.
