    <p>
    Cameron Hotchkies discovered an error within the parsing of ASN.1 BER
    encoded packets in the "ber_get_next()" function in
    libraries/liblber/io.c.
    </p>
  </description>
  <impact type="low">
    <p>
    A remote unauthenticated attacker can send a specially crafted ASN.1
    BER encoded packet which will trigger the error and cause an
    "assert()", terminating the "slapd" daemon.
    </p>
  </impact>
  <workaround>
    <p>
    There is no known workaround at this time.
    </p>
  </workaround>
  <resolution>
    <p>
    All OpenLDAP users should upgrade to the latest version:
    </p>
    <code>
    # emerge --sync
    # emerge --ask --oneshot --verbose "&gt;=net-nds/openldap-2.3.43"</code>
