Description:   A vulnerability was reported in the D-Link DWL-G132 wireless USB adapter. A remote user can execute arbitrary code on the target system.

A remote user on the wireless network can send an 802.11 beacon request containing a specially crafted rates information element field value to trigger a stack overflow in the 'A5AGU.SYS' driver and execute arbitrary code on the target system. The code will run with kernel level privileges on the target service.

H D Moore discovered this vulnerability.

http://projects.info-pull.com/mokb/MOKB-13-11-2006.html

Impact:   A remote user on the wireless network can execute arbitrary code on the target system.
Solution:   No solution was available at the time of this entry.

The original advisory contains the following unofficial workaround [quoted]:

"To install a patched version of the A5AGU.SYS driver, first install the WUA-2340 driver from the link below [http://support.dlink.com/products/view.asp?productid=WUA-2340], then re-install the DWL-G132 driver. Browse to the WUA-2340 installation path, find the Drivers subdirectory, and copy all of these files (at least, the .SYS and .BIN files), to your Windows\System32\Drivers directory, overwriting the existing files with the same name. Finally, reboot your system."
