Summary
Updated ntp packages fix security vulnerabilities
Details

Updated ntp packages fix security vulnerabilities:

The symmetric-key feature in the receive function in ntp_proto.c in ntpd in NTP before 4.2.8p2 requires a correct MAC only if the MAC field has a nonzero length, which makes it easier for man-in-the-middle attackers to spoof packets by omitting the MAC (CVE-2015-1798).

The symmetric-key feature in the receive function in ntp_proto.c in ntpd in NTP before 4.2.8p2 performs state-variable updates upon receiving certain invalid packets, which makes it easier for man-in-the-middle attackers to cause a denial of service (synchronization loss) by spoofing the source IP address of a peer (CVE-2015-1799).
