  utilities used to query and configure the ntpd service.

Security Fix(es):

  * Two vulnerabilities were discovered in the NTP server's parsing of
configuration directives. A remote, authenticated attacker could cause ntpd
to crash by sending a crafted message. (CVE-2017-6463, CVE-2017-6464)

  * A vulnerability was found in NTP, in the parsing of packets from the
/dev/datum device. A malicious device could send crafted messages, causing
ntpd to crash. (CVE-2017-6462)

Red Hat would like to thank the NTP project for reporting these issues.
Upstream acknowledges Cure53 as the original reporter of these issues.");
