    <p>
    Przemyslaw Frasunek discovered several flaws in lukemftpd, which also apply
    to Heimdal ftpd's out-of-band signal handling code.
    </p>
    <p>
    Additionally, a potential vulnerability that could lead to Denial of
    Service by the Key Distribution Center (KDC) has been fixed in this
    version.
    </p>
  </description>
  <impact type="high">
    <p>
    A remote attacker could be able to run arbitrary code with escalated
    privileges, which can result in a total compromise of the server.
    </p>
  </impact>
  <workaround>
    <p>
    There is no known workaround at this time.
    </p>
  </workaround>
  <resolution>
    <p>
    All Heimdal users should upgrade to the latest version:
    </p>
    <code>
    # emerge sync

    # emerge -pv "&gt;=app-crypt/heimdal-0.6.3"
    # emerge "&gt;=app-crypt/heimdal-0.6.3"</code>
  </resolution>
