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.

A denial of service flaw was found in the way neutron handled the
'dns_nameservers' parameter. By providing specially crafted
'dns_nameservers' values, an authenticated user could use this flaw to
crash the neutron service. (CVE-2014-7821)

Red Hat would like to thank the OpenStack project for reporting this issue.
Upstream acknowledges Henry Yamauchi, Charles Neill, and Michael Xin
(Rackspace) as the original reporters.

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