  <background>
    <p>mbed TLS (previously PolarSSL) is an “easy to understand, use,
      integrate and expand” implementation of the TLS and SSL protocols and
      the respective cryptographic algorithms and support code required.
    </p>
  </background>
  <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, through multiple vectors, 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
      # emerge --ask --oneshot --verbose "&gt;=net-libs/mbedtls-2.7.2"
    </code>
