Description

A vulnerability in the IP Device Tracking function in Cisco IOS could allow a remote, unauthenticated attacker to trigger a denial of service condition resulting in a reload of the device.

It should be noted that while the vendor describes a possible workaround, this plugin does not test for the presence of that workaround.
