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.

2014.1.3, which provides a number of bug fixes and enhancements over the
previous version. (BZ#1149753)

packages, which correct these issues and add these enhancements.
