Solution

This update is available via the Red Hat Network. Details on how to use the Red Hat Network to apply this update are available at https://access.redhat.com/articles/11258

Summary

OpenStack Networking (neutron) is a pluggable, scalable, and API-driven system that provisions networking services to virtual machines. Its main function is to manage connectivity to and from virtual machines. As of Red Hat Enterprise Linux OpenStack Platform 4.0, 'neutron' replaces 'quantum' as the core component of OpenStack Networking.
It was discovered that the openstack-neutron package in Red Hat Enterprise Linux Open Stack Platform 5.0 for Red Hat Enterprise Linux 6 was released with a sudoers file containing a configuration error. This error caused OpenStack Networking to be vulnerable to the CVE-2013-6433 issue. (CVE-2014-3632)
This update also fixes the following bugs:
* Prior to this update, the Open vSwitch agent failed to process ports on the integration bridge that quickly disappeared and reappeared during the processing loop. When such a failure occurred, the processing of the port was aborted (which is the correct behavior), but it was also marked as processed, meaning that the next updates for the port were not applied when it reappeared later. As a consequence, some ports were not VLAN-tagged correctly, and that resulted in no network connectivity for those instances that were bound to those ports. With this update, ports that are not on the integration bridge are still not processed but also not marked as such. Ports that disappear and then reappear later on the integration bridge are processed correctly, and VLAN tag updates are properly applied. (BZ#1123053)
* This update fixes an issue that caused connectivity to be dropped when restarting the openvswitch service with l2pop enabled. (BZ#1120719)
* Due to an incorrect version of the python-httplib2 package specified in the spec file, when a large amount of virtual machines (VMs) was launched, some of the VMs could be assigned two private IP addresses. (BZ#1126451)
All openstack-neutron users are advised to upgrade to these updated packages, which correct these issues.
