pcs (SL7)

Synopsis: Moderate: pcs security, bug fix, and enhancement update
Advisory ID: SLSA-2015:2290-1
Issue Date: 2015-11-19
CVE Numbers: CVE-2015-3225

A flaw was found in a way Rack processed parameters of incoming requests.
An attacker could use this flaw to send a crafted request that would cause
an application using Rack to crash. (CVE-2015-3225)

The pcs package has been upgraded to upstream version 0.9.143, which
provides a number of bug fixes and enhancements over the previous version.

* The pcs resource move and pcs resource ban commands now display a
warning message to clarify the commands’ behavior

* New command to move a Pacemaker resource to its preferred node

This update also fixes the following bugs:

* Before this update, a bug caused location, ordering, and colocation
constraints related to a resource group to be removed when removing any
resource from that group. This bug has been fixed, and the constraints are
now preserved until the group has no resources left, and is removed.

* Previously, when a user disabled a resource clone or multi-state
resource, and then later enabled a primitive resource within it, the clone
or multi-state resource remained disabled. With this update, enabling a
resource within a disabled clone or multi-state resource enables it.

* When the web UI displayed a list of resource attributes, a bug caused
the list to be truncated at the first “=” character. This update fixes the
bug and now the web UI displays lists of resource attributes correctly.

* The documentation for the “pcs stonith confirm” command was not clear.
This could lead to incorrect usage of the command, which could in turn
cause data corruption. With this update, the documentation has been
improved and the “pcs stonith confirm” command is now more clearly

* Previously, if there were any unauthenticated nodes, creating a new
cluster, adding a node to an existing cluster, or adding a cluster to the
web UI failed with the message “Node is not authenticated”. With this
update, when the web UI detects a problem with authentication, the web UI
displays a dialog to authenticate nodes as necessary.

* Previously, the web UI displayed only primitive resources. Thus there
was no way to set attributes, constraints and other properties separately
for a parent resource and a child resource. This has now been fixed, and
resources are displayed in a tree structure, meaning all resource elements
can be viewed and edited independently.

In addition, this update adds the following enhancements:

* A dashboard has been added which shows the status of clusters in the web
UI. Previously, it was not possible to view all important information
about clusters in one place. Now, a dashboard showing the status of
clusters has been added to the main page of the web UI.

* With this update, the pcsd daemon automatically synchronizes pcsd
configuration across a cluster. This enables the web UI to be run from any
node, allowing management even if any particular node is down.

* The web UI can now be used to set permissions for users and groups on a
cluster. This allows users and groups to have their access restricted to
certain operations on certain clusters.
