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.

Statistics File Issues
can generate a variety of statistics as it runs.
Over time, any of these statistics files may have undergone a change in its content or format which makes it difficult to analyze "previous" and "current" data.
Let's use this page to discuss these issues and evolve a solution.
What about generating a "comment line" as the first line generated for every statistics file?
Perhaps something like:
# day now offset freq*1e6 jitter stability*1e6 spoll
This way we could easily
out the comment lines and/or use a perl program to combine data from different versions of each statistics file into the desired format.

I like that idea, but I would like to take it a step further. I think that the format line should be inserted every time ntpd starts up. Because the ntp.conf file is largely backwards compatible, users often will switch between versions of ntpd and xntpd without changing the names of the stats files, so it is possible to get a mix of formats in a single file.
