Description Johannes Segitz 2016-01-21 13:03:31 UTC
http://support.ntp.org/bin/view/Main/NtpBug2946

Summary: To prevent off-path attackers from impersonating legitimate peers, clients require that the origin timestamp in a received response packet match the transmit timestamp from its last request to a given peer. Under assumption that only the recipient of the request packet will know the value of the transmit timestamp, this prevents an attacker from forging replies.
Comment 1 Johannes Segitz 2016-01-21 13:04:08 UTC
Upstream decided not to patch this issue.

Mitigation:
-    Configure ntpd to get time from multiple sources.
-    Configure ntpd with restrict statements to limit who is allowed to issue ntpq and ntpdc queries. Note that ntpdc queries are disabled by default.
-    Monitor your ntpd instances.
