MOKB-11-11-2006: Broadcom Wireless Driver Probe Response SSID Overflow

The Broadcom BCMWL5.SYS wireless device driver is vulnerable to a stack-based buffer overflow that can lead to arbitrary kernel-mode code execution. This particular vulnerability is caused by improper handling of 802.11 probe responses containing a long SSID field. The BCMWL5.SYS driver is bundled with new PCs from HP, Dell, Gateway, eMachines, and other computer manufacturers.
