The remote service is vulnerable to a denial of service attack.
The remote host is running a Kerberos server that seems to be
vulnerable to a 'ping-pong' attack.
When contacted on the UDP port, this service always responds, even to
malformed requests. This makes it possible to involve it in a
'ping-pong' attack, in which an attacker spoofs a packet between two
machines running this service, causing them to spew characters at each
other, slowing the machines down and saturating the network.

Risk factor :

Nessus Plugin ID: 10640 (krb_pingpong.nasl)
