Cisco IOS Software Network Address Translation Vulnerabilities

The Cisco IOS Software Network Address Translation (NAT) feature contains two denial of service (DoS) vulnerabilities in the translation of IP packets.

The vulnerabilities are caused when packets in transit on the vulnerable device require translation.

Cisco has released software updates that address these vulnerabilities.
