    - CVE-2019-6442: "An authenticated attacker can write one byte out of
      bounds in ntpd via a malformed config request, related to
      config_remotely in ntp_config.c, yyparse in ntp_parser.tab.c, and
      yyerror in ntp_parser.y."
    - CVE-2019-6443: "Because of a bug in ctl_getitem, there is a stack-based
      buffer over-read in read_sysvars in ntp_control.c in ntpd.
    - CVE-2019-6444: "process_control() in ntp_control.c has a stack-based
      buffer over-read because attacker-controlled data is dereferenced by
      ntohl() in ntpd."
    - CVE-2019-6445: "An authenticated attacker can cause a NULL pointer
      dereference and ntpd crash in ntp_control.c, related to ctl_getitem."
