An off-path attacker can cause a preemptible client association to be
demobilized in NTP 4.2.8p4 and earlier and NTPSec
a5fb34b9cc89b92a8fef2f459004865c93bb7f92 by sending a crypto NAK packet to
a victim client with a spoofed source address of an existing associated
peer. This is true even if authentication is enabled.
