NTP ntpd -u Group Permission Weakness

This script is Copyright (C) 2005-2014 Tenable Network Security, Inc.

Synopsis :

The remote NTP server is affected by a privilege escalation issue.

Description :

According to its version number, the NTP (Network Time Protocol)
server installed on the remote host suffers from a flaw that may cause
it to run with the permissions of a privileged user if a group name
rather than a group id is specified on the commandline. As a result,
an attacker that manages to compromise the application through some
other means will gain elevated privileges than what is expected.

Solution :

Start ntpd with a group number or upgrade to NTP 4.2.1 or later.

Risk factor :

Low / CVSS Base Score : 2.1
CVSS Temporal Score : 1.8
