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-4.2.8p15 was released on 23 June 2020. It addresses 1 medium-severity security issue in ntpd, and provides 13 non-security bugfixes over 4.2.8p13.

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

I am inclined to "flush" the ntp-dev/ area whenever a new stable release is made.

The ntp-4.*/ subdirs contain *.diff.gz files and "significant" tarballs.

The snapshots/ subdir is a relatively recent addition; it contains snapshot tarballs.
