The Cisco IOS Software network address translation (NAT) feature contains multiple denial of 
service (DoS) vulnerabilities in the translation of the following protocols:

NetMeeting Directory (Lightweight Directory Access Protocol, LDAP)

Session Initiation Protocol (Multiple vulnerabilities)

H.323 protocol

All the vulnerabilities described in this document are caused by packets in transit on the affected 
devices when those packets require application layer translation.

Cisco has released free software updates that address these vulnerabilities.
