CWE-17  (opens in a new tab)

How to fix?

Upgrade Oracle:7 sntp to version 0:4.2.6p5-22.el7 or higher.
This issue was patched in ELSA-2015-2231.

NVD Description

Note: Versions mentioned in the description apply only to the upstream sntp package and not the sntp package as distributed by Oracle. See How to fix? for Oracle:7 relevant fixed versions and status.

The symmetric-key feature in the receive function in ntp_proto.c in ntpd in NTP 4.x 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.
