CVE-2018-7184

ntpd in ntp 4.2.8p4 before 4.2.8p11 drops bad packets before updating the
“received” timestamp, which allows remote attackers to cause a denial of
service (disruption) by sending a packet with a zero-origin timestamp
causing the association to reset and setting the contents of the packet as
the most recent timestamp. This issue is a result of an incomplete fix for
CVE-2015-7704.
