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 unprivileged users could in some cases reset
admin-only network attributes to their default values. This could lead to
unexpected behavior or in some cases result in a denial of service.
(CVE-2014-6414)

These updated packages also fix various bugs. Documentation for these bug
fixes is available in the Technical Notes document linked to in the
References section.

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