MadWifi prior to 0.9.3.3 allowed remote attackers to cause a denial of service via a beacon frame with a large length value in the extended supported rates element, which would trigger an assertion error. Updated packages have been updated to 0.9.3.3 to correct this issue. Wpa_supplicant is built using madwifi-source and has been rebuilt using 0.9.3.3 source.
