    Synopsis:          Low: openstack-neutron security and bug fix update
    Advisory ID:       RHSA-2014:1339-01
    Product:           Red Hat Enterprise Linux OpenStack Platform
    Advisory URL:
    Issue date:        2014-09-30
    CVE Names:         CVE-2014-3632 
    1. Summary:
    Updated openstack-neutron packages that fix one security issue and several
    bugs are now available for Red Hat Enterprise Linux OpenStack Platform 5.0
    for Red Hat Enterprise Linux 6.
    Red Hat Product Security has rated this update as having Low 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 OpenStack Platform 5.0 for RHEL 6 - noarch
    3. Description:
    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.
    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.
    * 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.
    4. Solution:
    Before applying this update, make sure all previously released errata
    relevant to your system have been applied.
    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
    5. Bugs fixed (
    1126451 - VMs get 2 private IPs during launching of a large amount of VMs
    1128194 - LBaaS extension doesn't register it's resources to quota engine
    1140949 - CVE-2014-3632 openstack-neutron: regression of fix for CVE-2013-6433
