Synopsis: Low: openstack-neutron security and bug fix update

Advisory ID: RHSA-2014:1339-01

Product: Red Hat Enterprise Linux OpenStack Platform

Advisory URL: https://rhn.redhat.com/errata/RHSA-2014-1339.html

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.

(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.

 

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

https://access.redhat.com/articles/11258

 

5. Bugs fixed (https://bugzilla.redhat.com/):

 

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
