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 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.

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).

Bug Fix(es) :

* The version of Pacemaker in Red Hat Enterprise Linux 7.3 incorporated an increase in the version number of the remote node protocol. Consequently, cluster nodes running Pacemaker in Red Hat Enterprise Linux 7.3 and remote nodes running earlier versions of Red Hat Enterprise Linux were not able to communicate with each other unless special precautions were taken. This update preserves the rolling upgrade capability. (BZ#1389023)

Jan Pokorny and Alain Moulle discovered that Pacemaker incorrectly handled the IPC interface. A local attacker could possibly use this issue to execute arbitrary code with root privileges. (CVE-2016-7035)

Alain Moulle discovered that Pacemaker incorrectly handled authentication. A remote attacker could possibly use this issue to shut down connections, leading to a denial of service. This issue only affected Ubuntu 16.04 LTS. (CVE-2016-7797).

Note that Tenable Network Security has extracted the preceding description block directly from the Ubuntu security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

Bug Fix(es) :

  - The version of Pacemaker in Scientific Linux 7.3     incorporated an increase in the version number of the     remote node protocol. Consequently, cluster nodes     running Pacemaker in Scientific Linux 7.3 and remote     nodes running earlier versions of Scientific Linux were     not able to communicate with each other unless special     precautions were taken.
