Synopsis

The remote Red Hat host is missing a security update.

Description

The remote Redhat Enterprise Linux 7 host has packages installed that are affected by a vulnerability as referenced in the RHSA-2016:2578 advisory.

The Pacemaker cluster resource manager is a collection of technologies working together to provide data integrity and the ability to maintain application availability in the event of a failure.

The following packages have been upgraded to a newer upstream version: pacemaker (1.1.15). (BZ#1304771)

Security Fix(es):

* It was found that the connection between a pacemaker cluster and a pacemaker_remote node could be shut down using a new unauthenticated connection. A remote attacker could use this flaw to cause a denial of service. (CVE-2016-7797)

Red Hat would like to thank Alain Moulle (ATOS/BULL) for reporting this issue.

Additional Changes:

For detailed information on changes in this release, see the Red Hat Enterprise Linux 7.3 Release Notes linked from the References section.

Tenable has extracted the preceding description block directly from the Red Hat Enterprise Linux security advisory.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Update the affected packages.
