Summary
A vulnerability in the function that performs IP version 6 (IPv6) Network
Address Translation (NAT) for Cisco ASA Software could allow an
unauthenticated, remote attacker to cause a reload of an affected system.
The vulnerability is due to improper implementation of the logic that performs
NAT when the Cisco ASA is configured for NAT64 or NAT66. This vulnerability
can be triggered only under specific configurations. An attacker could exploit
this vulnerability by sending packets matching one of the NAT rules through
the affected system. An exploit could allow the attacker to cause a reload of
the system, leading to a denial of service (DoS) condition.
