  <description>
    <p>Multiple format string vulnerabilities in FlightGear and SimGear allow
      user-assisted remote attackers to cause a denial of service and possibly
      execute arbitrary code via format string specifiers in certain data chunk
      values in an aircraft xml model.
    </p>
  </description>
  <impact type="normal">
    <p>Remote attackers could possibly execute arbitrary code or cause Denial
      of Service.

  </impact>
  <workaround>
    <p>There is no known workaround at this time.</p>
  </workaround>
  <resolution>
    <p>All Flightgear users should upgrade to the latest version:</p>
