1. Summary:
An update for pacemaker is now available for Red Hat Enterprise Linux 6.
Red Hat Product Security has rated this update as having a security impact
of Important. A Common Vulnerability Scoring System (CVSS) base score,
which gives a detailed severity rating, is available for each vulnerability
from the CVE link(s) in the References section.
2. Relevant releases/architectures:

3. Description:
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).
