Summary
Red Hat Security Advisory: pacemaker security, bug fix, and enhancement update

Notes

Topic
An update for pacemaker is now available for Red Hat Enterprise Linux 7. Red Hat Product Security has rated this update as having a security impact of Moderate. 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.
Details
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.
