Scientific Linux Security Update : ntp on SL6.x, SL7.x i386/x86_64

Medium Nessus Plugin ID 88175

Synopsis

The remote Scientific Linux host is missing one or more security updates.

Description

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)

After installing the update, the ntpd daemon will restart automatically.

Solution

Update the affected packages.
