+ <impact type="normal">
+ <p>
+ A remote attacker could act as an access point and send a specially
+ crafted packet to an Atheros based wireless client, possibly resulting
+ in a Denial of Service (kernel panic).
+ </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-0.9.3.3"</code>
