NTP users are strongly urged to take immediate action to ensure that their NTP daemons are not susceptible to being used in distributed denial-of-service (DDoS) attacks. Please also take this opportunity to defeat denial-of-service attacks by implementing Ingress and Egress filtering through BCP38.

ntp-4.2.8p14 was released on 03 March 2020. It addresses 2 medium-severity security issues in ntpd, and provides 47 non-security bugfixes and 4 other improvements over 4.2.8p13.

Please see the NTP Security Notice for vulnerability and mitigation details.
