Red Hat Security Advisory

Synopsis: Moderate: openstack-neutron security and bug fix update
Advisory ID: RHSA-2015:1909-01
Product: Red Hat Enterprise Linux OpenStack Platform
Advisory URL: https://rhn.redhat.com/errata/RHSA-2015-1909.html
Issue date: 2015-10-15
CVE Names: CVE-2015-5240
=====================================================================

1. Summary:

Updated openstack-neutron packages that fix one security issue are now
available for Red Hat Enterprise Linux OpenStack Platform 5.0, 6.0, and
7.0.

Red Hat Product Security has rated this update as having Moderate 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
Red Hat Enterprise Linux OpenStack Platform 5.0 for RHEL 7 - noarch
Red Hat Enterprise Linux OpenStack Platform 6.0 for RHEL 7 - noarch
Red Hat Enterprise Linux OpenStack Platform 7.0 for RHEL 7 - 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.

A race-condition flaw leading to ACL bypass was discovered in OpenStack
Networking. An authenticated user could change the owner of a
port after it was created but before firewall rules were applied, thus
preventing firewall control checks from occurring. All OpenStack Networking
deployments that used either the ML2 plug-in or a plug-in that relied on
the
security groups AMQP API were affected. (CVE-2015-5240)

Red Hat would like to thank the OpenStack project for reporting this issue.
Upstream acknowledges Kevin Benton from Mirantis as the original reporter.

All openstack-neutron users are advised to upgrade to these updated
packages, which contain backported patches to correct these issues.

4. Solution:

Before applying this update, ensure all previously released errata
relevant to your system have been applied.

This update is available through 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
