Cisco IOS XR Software IPv6 Malformed Packet DoS (cisco-sa-20140611-ipv6)

This script is Copyright (C) 2014-2017 Tenable Network Security, Inc.

Synopsis :

The remote device is missing a vendor-supplied security patch.

Description :

According to its self-reported version, the version of Cisco IOS XR
running on the remote host is affected by a denial of service
vulnerability due to the improper handling of IPv6 packets. A remote,
unauthenticated attacker can cause the device to lock up by rapidly
sending specially crafted IPv6 packets.

Note that this issue only affects Trident-based line cards on Cisco
ASR 9000 series routers. Also, if IPv6 is not enabled, the device can
still be exploited by a host on an adjacent network.
