(RHSA-2014:0516) Moderate: openstack-neutron security, bug fix, and enhancement update

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.

A flaw was found in the way OpenStack Networking performed authorization
checks on created ports. An authenticated user could potentially use this
flaw to create ports on a router belonging to a different tenant, allowing
unauthorized access to the network of other tenants. Note that only
OpenStack Networking setups using plug-ins that rely on the l3-agent were
affected. (CVE-2014-0056)

It was discovered that the default sudo configuration provided in OpenStack
Networking, which is specific to the openstack-neutron package shipped by
Red Hat, did not correctly specify a configuration file for rootwrap,
potentially allowing an unauthenticated user to escalate their privileges.
(CVE-2013-6433)

Red Hat would like to thank the OpenStack project for reporting
CVE-2014-0056. Upstream acknowledges Aaron Rosen from VMware as the
original reporter of CVE-2014-0056. The CVE-2013-6433 issue was discovered
by Kashyap Chamarthy of Red Hat.

This update also fixes several bugs and adds enhancements. Documentation
for these changes 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 and add these enhancements.
