    <p>
    The Coverity Scan project has discovered a memory leak within the
    handling of certain malformed Diameter format values inside an EAP-TTLS
    tunnel.
    </p>
  </description>
  <impact type="normal">
    <p>
    A remote attacker could send a large amount of specially crafted
    packets to a FreeRADIUS server using EAP-TTLS authentication and
    exhaust all memory, possibly resulting in a Denial of Service.
    </p>
  </impact>
  <workaround>
    <p>
    There is no known workaround at this time.
    </p>
  </workaround>
  <resolution>
    <p>
    All FreeRADIUS users should upgrade to the latest version:
    </p>
    <code>
    # emerge --sync
    # emerge --ask --oneshot --verbose &quot;&gt;=net-dialup/freeradius-1.1.6&quot;</code>
  </resolution>
