Cisco IOS Software Network Address Translation Vulnerabilities

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 software updates that address these vulnerabilities.
