https://notcve.org/view.php?id=CVE-2016-7429
13 Jan 2017 — NTP before 4.2.8p9 changes the peer structure to the interface it receives the response from a source, which allows remote attackers to cause a denial of service (prevent communication with a source) by sending a response for a source to an interface the source does not use.
