synchronize a computer's time with a referenced time source.

It was discovered that ntpd as a client did not correctly check the
originate timestamp in received packets. A remote attacker could use this
flaw to send a crafted packet to an ntpd client that would effectively
disable synchronization with the server, or push arbitrary offset/delay
measurements to modify the time on the client. (CVE-2015-8138)

All ntp users are advised to upgrade to these updated packages, which
contain a backported patch to resolve this issue. After installing the
update, the ntpd daemon will restart automatically.
