CVE-2015-7704

It was discovered that ntpd as a client did not correctly check timestamps in Kiss-of-Death packets. A remote attacker could use this flaw to send a crafted Kiss-of-Death packet to an ntpd client that would increase the client's polling interval value, and effectively disable synchronization with the server.

This issue did not affect the versions of ntp as shipped with Red Hat Enterprise Linux 5 and Red Hat Enterprise Linux 6.4, as they do not include support for KoD packets.
