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.

5. Bugs fixed (https://bugzilla.redhat.com/):
1240330 - fencing adjacent node occurs even if the stonith resource is Stopped
1268313 - clvmd/dlm resource agent monitor action should recognize it is hung
1281450 - stonith_admin strips description from fence agents' metadata
1284069 - Pacemaker's lrmd crashes after certain systemd errors
1287315 - Updating a fencing device will sometimes result in it no longer being registered
1288929 - service pacemaker_remote stop causes node to be fenced
1304771 - Rebase Pacemaker for bugfixes and features
1310486 - Pacemaker looses shutdown requests under some conditions
1312094 - crmd can crash after unexpected remote connection takeover
1314157 - crm_report -l does not work correctly
1323544 - Better handling of remote nodes when generating crm_reports
1327469 - pengine wants to start services that should not be started
1338623 - pacemaker does not flush the attrd cache fully after a crm_node -R node removal
1345876 - Restarting a resource in a resource group on a remote node restarts other services instead
1346726 - Backport upstream bug systemd: Return PCMK_OCF_UNKNOWN_ERROR instead of PCMK_OCF_NOT_INSTALLED for uncertain errors on LoadUnit
1361533 - missing header for the resources section in the crm_mon output when called without --inactive flag
1372009 - pacemaker-remote rpm does not properly restart pacemaker_remote during package upgrade, potentially triggering a watchdog fence
1379784 - CVE-2016-7797 pacemaker: pacemaker remote nodes vulnerable to hijacking, resulting in a DoS attack
