1607822: CVE-2018-14635 openstack-neutron: A router interface out of subnet IP range results in a denial of service
When using the Linux bridge ml2 driver, non-privileged tenants are able to create and attach ports without specifying an IP address, bypassing IP address validation. A potential denial of service could occur if an IP address, conflicting with existing guests or routers, is then assigned from outside of the allowed allocation pool.
