-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 ===================================================================== Red Hat Security Advisory Synopsis: Moderate: pacemaker security, bug fix, and enhancement update Advisory ID: RHSA-2016:2578-02 Product: Red Hat Enterprise Linux Advisory URL: https://rhn.redhat.com/errata/RHSA-2016-2578.html Issue date: 2016-11-03 CVE Names: CVE-2016-7797 ===================================================================== 1. Summary: 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. 2. Relevant releases/architectures: Red Hat Enterprise Linux Server High Availability (v. 7) - s390x, x86_64 Red Hat Enterprise Linux Server Resilient Storage (v. 7) - s390x, x86_64 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. 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. 4. Solution: For details on how to apply this update, which includes the changes described in this advisory, refer to: https://access.redhat.com/articles/11258 5.
