Scientific Linux Security Update : pacemaker on SL6.x i386/x86_64 (20150722)

high Nessus Plugin ID 85204

Language:

Synopsis

The remote Scientific Linux host is missing one or more security updates.

Description

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.

Solution

Update the affected packages.
