high Nessus Plugin ID 91662
New! Plugin Severity Now Using CVSS v3

The calculated severity for Plugins has been updated to use CVSS v3 by default. Plugins that do not have a CVSS v3 score will fall back to CVSS v2 for calculating severity. Severity display preferences can be toggled in the settings dropdown.

Synopsis

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

Description

ntp was updated to version 4.2.8p8 to fix five security issues.

These security issues were fixed :

- CVE-2016-4953: Bad authentication demobilizes ephemeral associations (bsc#982065).

- CVE-2016-4954: Processing spoofed server packets (bsc#982066).

- CVE-2016-4955: Autokey association reset (bsc#982067).

The update package also includes non-security fixes. See advisory for details.

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.
