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


Synopsis :

The remote SUSE host is missing one or more security updates.

Description :

ntp was updated to fix two security related flaws as well as 'slew'
mode handling for leap seconds.

The following vulnerabilities were fixe :

- ntpd could accept unauthenticated packets with symmetric
key crypto. (CVE-2015-1798)

- ntpd authentication did not protect symmetric
associations against DoS attacks (CVE-2015-1799)

- ntp-keygen may generate non-random symmetric keys on
big-endian systems (bsc#928321, CVE-2015-3405).

The following non-security issues were fixed :

- Fix slew mode for leap seconds (bnc#918342).

Note that Tenable Network Security has extracted the preceding
description block directly from the SUSE security advisory. Tenable
has attempted to automatically clean and format it as much as possible
without introducing additional issues.
