Summary
=======

A vulnerability in the Internet Key Exchange (IKE) version 1 (v1) and
IKE version 2 (v2) code of Cisco ASA Software could allow an
unauthenticated, remote attacker to cause a reload of the affected
system or to remotely execute code.

The vulnerability is due to a buffer overflow in the affected code
area. An attacker could exploit this vulnerability by sending crafted
UDP packets to the affected system. An exploit could allow the attacker
to execute arbitrary code and obtain full control of the system or to
cause a reload of the affected system.

Note: Only traffic directed to the affected system can be used to
exploit this vulnerability. This vulnerability affects systems
configured in routed firewall mode only and in single or multiple
