  <description>
    <p>Multiple vulnerabilities have been discovered in mbed TLS. Please review
      the CVE identifiers referenced below for details.
    </p>
  </description>
  <impact type="high">
    <p>A remote attacker could possibly execute arbitrary code with the
      privileges of the process, or cause a Denial of Service condition.
    </p>
  </impact>
  <workaround>
    <p>There is no known workaround at this time.</p>
  </workaround>
  <resolution>
    <p>All mbed TLS users should upgrade to the latest version:</p>
    
    <code>
      # emerge --sync
