http://www.cs.bu.edu/~goldbe/NTPattack.html says

Attack 1 and Attack 2 (Denial of Service). Upgrade to ntpd v4.2.8p4. To
see what ntpd version you are running, log into to your NTP server and
type ntpq and then rv. Also, monitor the system log for error messages
of the form "receive: Unexpected origin timestamp from %s", which could
indicate that you are subject to a priming-the-pump attack.

Hello,

thank you for spending your time helping to make Debian better with
this bug report. Unfortunately your bug report could not be (completely)
dealt with in an appropriate time.

The version you have filed this bug report against is for a release that
is not supported anymore. Unfortunately we do not have the manpower to
reproduce bugs that old. It is possibly already fixed with the current
version.

Therefor I'm closing this bug. If you can still reproduce this issue on
a supported release (Debian 9 aka stretch, preferably also in sid) feel
free to reopen the bug report.

Thanks,
Bernhard
