Synopsis:          Moderate: pacemaker security and bug fix update
Advisory ID:       SLSA-2015:1424-1
Issue Date:        2015-07-22
CVE Numbers:       CVE-2015-1867
--

A flaw was found in the way pacemaker, a cluster resource manager,
evaluated added nodes in certain situations. A user with read-only access
could potentially assign any other existing roles to themselves and then
add privileges to other users as well. (CVE-2015-1867)

This update also fixes the following bugs:

* Due to a race condition, nodes that gracefully shut down occasionally
had difficulty rejoining the cluster. As a consequence, nodes could come
online and be shut down again immediately by the cluster. This bug has
been fixed, and the "shutdown" attribute is now cleared properly.

* Prior to this update, the pacemaker utility caused an unexpected
termination of the attrd daemon after a system update to Scientific Linux
6.6. The bug has been fixed so that attrd no longer crashes when pacemaker
starts.

* Previously, the access control list (ACL) of the pacemaker utility
allowed a role assignment to the Cluster Information Base (CIB) with a
read-only permission. With this update, ACL is enforced and can no longer
be bypassed by the user without the write permission, thus fixing this
bug.

* Prior to this update, the ClusterMon (crm_mon) utility did not trigger
an external agent script with the "-E" parameter to monitor the Cluster
Information Base (CIB) when the pacemaker utility was used. A patch has
been provided to fix this bug, and crm_mon now calls the agent script when
the "-E" parameter is used.
