Description
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 SLES for vRealize to dynamically load a protocol handler by opening a socket using the protocol.
