3. Description:

OpenStack Orchestration (heat) is a template-driven engine used to specify and deploy configurations for Compute, Storage, and OpenStack Networking. It can also be used to automate post-deployment actions, which in turn allows automated provisioning of infrastructure, services, and applications. Orchestration can also be integrated with Telemetry alarms to implement auto-scaling for certain infrastructure resources.

It was discovered that a user could temporarily be able to see the URL of a provider template used in another tenant. If the template itself could be accessed, then additional information could be leaked that would otherwise not be visible. (CVE-2014-3801)

The openstack-heat packages have been upgraded to upstream version 2013.2.4, which provides a number of bug fixes and enhancements over the previous version. The most notable enhancements are:

* Added OS profiler support into Orchestration (heat). * Multiple environment files can now be specified on the command line. * The command 'resource-list' now displays 'physical_resource_id'. (BZ#1146092)

This update also fixes the following bugs:

* Prior to this update, Qpid would attempt to reconnect to a broken message broker, even though multiple hosts were configured. With this update, reconnect() selects the next broker in the list for each connection attempt. (BZ#1082672)

* Prior to this update, certain Qpid exceptions were not properly handled by the Qpid driver. As a result, the Qpid connection would fail and stop processing subsequent messages. With this update, all possible exceptions are handled to ensure the Qpid driver does not enter an unrecoverable failure loop. Consequently, Orchestration (heat) will continue to process Qpid messages, even after a major exception occur. (BZ#1085996)

* The Qpid driver's v2 topology has been introduced to specifically address the slow growth of orphaned direct exchanges over time. By default, however, services still used the original v1 topology of the Qpid driver. The v2 topology had to be explicitly configured via the 'qpid_topology_version = 2' parameter. With this fix, the Orchestration service's distribution configuration file (/usr/share/heat/heat-dist.conf) now contains the 'qpid_topology_version = 2' parameter. This effectively sets the Qpid driver's v2 topology as the default. In addition, the default value in the Qpid implementation has been changed to 2 as well. (BZ#1124137)

* Previously, the version of Orchestration (heat) in Red Hat Enterprise Linux OpenStack Platform 4 did not include the "host_routes" property of the OS::Neutron::Subnet resource that was added in later releases of Orchestration. This change adds support for this property, which allows host routes to be specified for a subnet. (BZ#1095752)

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