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-4.2.8p11 was released on 27 February 2018. It addresses 2 low-/medium-, 1 informational-/medium-, and 2 low-severity security issues in ntpd, 1 medium-severity security issue in ntpq, and provides over 65 non-security bugfixes and other improvements over 4.2.8p10.

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

Implementation choices

The client (ntpd and/or ntpq) could send a very short dynamic page request with the version number, the XML of which tells the client if there's any newer stable release as well as if there are high-priority reasons to update from the given version.

We'd also have an html wrapper presenting the same info in human readable form, with a few more links.
