  <description>
    <p>
    Laurent Butti, Jerome Raznieski and Julien Tinnes reported a buffer
    overflow in the encode_ie() and the giwscan_cb() functions from
    ieee80211_wireless.c.
    </p>
  </description>
  <impact type="high">
    <p>
    A remote attacker could send specially crafted wireless WPA packets
    containing malicious RSN Information Headers (IE) that could
    potentially lead to the remote execution of arbitrary code as the root
    user.
    </p>
  </impact>
  <workaround>
    <p>
    There is no known workaround at this time.
    </p>
  </workaround>
  <resolution>
    <p>
    All MadWifi users should upgrade to the latest version:
    </p>
    <code>
    # emerge --sync
    # emerge --ask --oneshot --verbose "&gt;=net-wireless/madwifi-ng-0.9.2.1"</code>
