Title

The Lightweight User Datagram Protocol (UDP-Lite) must be disabled unless required. (Cat II impact)

Discussion

The Lightweight User Datagram Protocol (UDP-Lite) is a proposed transport layer protocol. This protocol is not yet widely used. Binding this protocol to the network stack increases the attack surface of the host. Unprivileged local processes may be able to cause the system to dynamically load a protocol handler by opening a socket using the protocol.

Check Content

If there is no UDP-Lite protocol handler available for the system, this is not applicable. Determine if the UDP-Lite protocol handler is prevented from dynamic loading. If it is not, this is a finding.

Fix Text

Configure the system to prevent the dynamic loading of the UDP-Lite protocol handler.
