CentOS Errata and Security Advisory CESA-2016:2578

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.
