AIX 7.1 TL 3 : ntp (IV74261)

This script is Copyright (C) 2015-2017 Tenable Network Security, Inc.

Synopsis :

The remote AIX host is missing a security patch.

Description :

The remote AIX host has a version of Network Time Protocol (NTP)
installed that is affected by a denial of service vulnerability due to
a flaw in the symmetric-key feature in the receive() function in file
ntp_proto.c when receiving certain invalid packets, which causes
state-variable updates to be performed. A man-in-the-middle attacker
can exploit this, by spoofing the source IP of a peer, to cause a
synchronization loss.
