Synopsis

The remote Red Hat host is missing a security update for pacemaker.

Description

The remote Redhat Enterprise Linux 6 host has packages installed that are affected by a vulnerability as referenced in the RHSA-2016:2675 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.

Security Fix(es):

* An authorization flaw was found in Pacemaker, where it did not properly guard its IPC interface. An attacker with an unprivileged account on a Pacemaker node could use this flaw to, for example, force the Local Resource Manager daemon to execute a script as root and thereby gain root access on the machine.
(CVE-2016-7035)

This issue was discovered by Jan poki Pokorny (Red Hat) and Alain Moulle (ATOS/BULL).

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