Synopsis

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

Description

The remote host is an MDS 9000 series router. It is, therefore, vulnerable to a denial of service vulnerability. A flaw with Virtual Router Redundancy Protocol (VRRP) frame handling allows a remote attacker, using a specially crafted VRRP frame with an Authentication Header (AH), to cause the device to have high CPU utilization and force a restart of the device.

Solution

Apply the patch referenced in Cisco bug ID CSCte27874.
