    Md Sohail Ahmad from AirTight Networks has discovered a divison by zero
    in the ath_beacon_config() function (CVE-2007-2830). The vendor has
    corrected an input validation error in the
    ieee80211_ioctl_getwmmparams() and ieee80211_ioctl_getwmmparams()
    functions(CVE-207-2831), and an input sanitization error when parsing
    nested 802.3 Ethernet frame lengths (CVE-2007-2829).
    </p>
  </description>
  <impact type="high">
    <p>
    An attacker could send specially crafted packets to a vulnerable host
    to exploit one of these vulnerabilities, possibly resulting in the
    execution of arbitrary code with root privileges, or a Denial of
    Service.
    </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-0.9.3.1"</code>
  </resolution>
