NTP before 4.2.8p7 and 4.3.x before 4.3.92 allows remote attackers to cause
a denial of service (prevent subsequent authentication) by leveraging
knowledge of the controlkey or requestkey and sending a crafted packet to
ntpd, which changes the value of trustedkey, controlkey, or requestkey.
NOTE: this vulnerability exists because of a CVE-2016-2516 regression.
