      sent, and also fails to properly verify a descriptor provided by a hidden
      service directory.
    </p>

  <impact type="normal">
    <p>A remote attacker could cause a Denial of Service condition in both a
      Tor client or a Tor server.

  </impact>
  <workaround>
    <p>There is no known workaround at this time.</p>
