The remote Redhat Enterprise Linux 7 host has packages installed that are affected by a vulnerability as referenced in the RHSA-2015:2383 advisory.

    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)

    The pacemaker packages have been upgraded to upstream version 1.1.13, which     provides a number of bug fixes and enhancements over the previous version.
    (BZ#1234680)

    This update also fixes the following bugs:

    * When a Pacemaker cluster included an Apache resource, and Apache's     mod_systemd module was enabled, systemd rejected notifications sent by     Apache. As a consequence, a large number of errors in the following format     appeared in the system log:

      Got notification message from PID XXXX, but reception only permitted       for PID YYYY

    With this update, the lrmd daemon now unsets the NOTIFY_SOCKET variable     in the described circumstances, and these error messages are no longer     logged. (BZ#1150184)

    * Previously, specifying a remote guest node as a part of a group resource     in a Pacemaker cluster caused the node to stop working. This update adds     support for remote guests in Pacemaker group resources, and the described     problem no longer occurs. (BZ#1168637)

    * When a resource in a Pacemaker cluster failed to start, Pacemaker updated     the resource's last failure time and incremented its fail count even if the     on-fail=ignore option was used. This in some cases caused unintended     resource migrations when a resource start failure occurred. Now, Pacemaker     does not update the fail count when on-fail=ignore is used. As a result,     the failure is displayed in the cluster status output, but is properly     ignored and thus does not cause resource migration. (BZ#1200849)

    * Previously, Pacemaker supported semicolon characters (;) as delimiters     when parsing the pcmk_host_map string, but not when parsing the     pcmk_host_list string. To ensure consistent user experience, semicolons are     now supported as delimiters for parsing pcmk_host_list, as well.
    (BZ#1206232)

    In addition, this update adds the following enhancements:

    * If a Pacemaker location constraint has the resource-discovery=never     option, Pacemaker now does not attempt to determine whether a specified     service is running on the specified node. In addition, if multiple location     constraints for a given resource specify resource-discovery=exclusive,     then Pacemaker attempts resource discovery only on the nodes specified in     those constraints. This allows Pacemaker to skip resource discovery on     nodes where attempting the operation would lead to error or other     undesirable behavior. (BZ#1108853)

    * The procedure of configuring fencing for redundant power supplies has     been simplified in order to prevent multiple nodes accessing cluster     resources at the same time and thus causing data corruption. For further     information, see the Fencing: Configuring STONITH chapter of the High     Availability Add-On Reference manual. (BZ#1206647)

    * The output of the crm_mon and pcs_status commands has been modified     to be clearer and more concise, and thus easier to read when reporting     the status of a Pacemaker cluster with a large number of remote nodes and     cloned resources. (BZ#1115840)

    All pacemaker users are advised to upgrade to these updated packages, which     correct these issues and add these enhancements.

Tenable has extracted the preceding description block directly from the Red Hat Enterprise Linux security advisory.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

As a result, the failure     is displayed in the cluster status output, but is     properly ignored and thus does not cause resource     migration.

Security fix for CVE-2015-1867: issue allegedly present in pacemaker-1.1.12, fixed in pacemaker-1.1.13. * * * pacemaker-1.1.13-3.fc{21,22,23} - Update to Pacemaker-1.1.13 post-release + patches (sync) - Add nagios-plugins-metadata subpackage enabling support of selected Nagios plugins as resources recognized by Pacemaker - Several specfile improvements: drop irrelevant stuff, rehash the included/excluded files + dependencies, add check scriptlet, reflect current packaging practice, do minor cleanups (mostly adopted from another spec)

The remote Redhat Enterprise Linux 6 host has packages installed that are affected by a vulnerability as referenced in the RHSA-2015:1424 advisory.

    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.

The remote host is affected by the vulnerability described in GLSA-201710-08 (Pacemaker: Multiple vulnerabilities)

    Multiple vulnerabilities have been discovered in Pacemaker. Please       review the referenced CVE identifiers for details.
  Impact :

    A remote attacker could execute arbitrary code or a local attacker could       escalate privileges.
  Workaround :

    There is no known workaround at this time.

  - 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.

A patch has been     provided to fix this bug, and crm_mon now calls the     agent script when the '-E' parameter is used.
