Title:	Cisco Products IPv6 Neighbor Discovery Crafted Packet Denial of Service Vulnerability (IOS XE)
Summary:	A vulnerability in the IP Version 6 (IPv6) packet processing functions of Cisco IOS XR Software,; Cisco IOS XE Software, and Cisco NX-OS Software could allow an unauthenticated, remote attacker to; cause an affected device to stop processing IPv6 traffic, leading to a denial of service (DoS); condition on the device.;; The vulnerability is due to insufficient processing logic for crafted IPv6 packets that are sent; to an affected device. An attacker could exploit this vulnerability by sending crafted IPv6; Neighbor Discovery packets to an affected device for processing. A successful exploit could allow; the attacker to cause the device to stop processing IPv6 traffic, leading to a DoS condition on; the device.;; Cisco will release software updates that address this vulnerability. There are no workarounds that; address this vulnerability.
