Title:
  [OSSA 2014-031] policy admin_only rules not enforced when changing
  value to default (CVE-2014-6414)

Status in OpenStack Neutron (virtual network service):
  Fix Released
Status in neutron havana series:
  Invalid
Status in neutron icehouse series:
  Fix Released
Status in OpenStack Security Advisories:
  Fix Released

Bug description:
  If a non-admin user tries to update an attribute, which should be
  updated only by admin, from a non-default value to default,  the
  update is successfully performed and PolicyNotAuthorized exception is
  not raised.

  The reason is that when a rule to match for a given action is built
  there is a verification that each attribute in a body of the resource
  is present and has a non-default value. Thus, if we try to change some
  attribute's value to default, it is not considered to be explicitly
  set and a corresponding rule is not enforced.
