-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 ===================================================================== Red Hat Security Advisory Synopsis: Moderate: pacemaker security and bug fix update Advisory ID: RHSA-2015:1424-01 Product: Red Hat Enterprise Linux Advisory URL: https://rhn.redhat.com/errata/RHSA-2015-1424.html Issue date: 2015-07-22 Updated on: 2015-03-31 CVE Names: CVE-2015-1867 ===================================================================== 1. Summary: Updated pacemaker packages that fix one security issue and several bugs are now available for Red Hat Enterprise Linux 6. Red Hat Product Security has rated this update as having Moderate security impact. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available from the CVE link in the References section. 2. Relevant releases/architectures: Red Hat Enterprise Linux High Availability (v. 6) - i386, x86_64 Red Hat Enterprise Linux Resilient Storage (v. 6) - i386, x86_64 3. Description: The Pacemaker 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. 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. (BZ#1198638) * Prior to this update, the pacemaker utility caused an unexpected termination of the attrd daemon after a system update to Red Hat Enterprise Linux 6.6. The bug has been fixed so that attrd no longer crashes when pacemaker starts. (BZ#1205292) * 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. (BZ#1207621) * 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. (BZ#1208896) Users of pacemaker are advised to upgrade to these updated packages, which contain backported patches to correct these issues. 4. Solution: Before applying this update, make sure all previously released errata relevant to your system have been applied.
