Summary

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.
