Synopsis :

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

Description :

A vulnerability in the IP version 6 (IPv6) packet handling routine of
Cisco NX-OS Software could allow an unauthenticated, adjacent attacker
to cause a device to stop responding to neighbor solicitation (NS)
requests, causing a limited denial of service (DoS) condition.

The vulnerability is due to improper processing of adjacencies in the
IPv6 neighbor table. An attacker could exploit this vulnerability by
sending a sequence of malformed IPv6 packets to an affected device. An
exploit could allow the attacker to cause a device to stop responding
to NS requests, causing a limited DoS condition.
