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

A new set of mode 6 vulnerabilities has been discovered and, while these vulnerabilities can be reduced by making sure you have restrict default noquery in your ntp.conf file, the best and most complete way to avoid these vulnerabilities is to install and deploy ntp-4.2.8 which was released on 18 December 2014.

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

NTF needs your help to qualify to participate in the Combined Federal Campaign so we can continue our mission to improve Network Time. We only need a few thousand dollars more by December 31st - any sized donation helps! Please join an NTF Consortium or make a donation to NTF now! THANKS!
