- The symmetric-key feature in the receive function in ntp_proto.c in ntpd in NTP 3.x and 4.x before 4.2.8p2 performs state-variable updates upon receiving certain invalid packets, which makes it easier for man-in- the-middle attackers to cause a denial of service (synchronization loss) by spoofing the source IP address of a peer.
