Security researchers have discovered a vulnerability
Flaws in handling 802.11 probe responses containing a long SSID field mean that systems that use the Broadcom BCMWL5.SYS wireless device driver are left open to buffer overflow attacks. The flaw might be used by hackers within radio range to inject hostile code into vulnerable systems. The list of potential targets (Broadcom partners) is extensive.
The flaw does not lend itself to remote attack across the internet but it does mean that hackers within radio range (for example when a user is in the vicinity of a hot spot used by an attacker) might be able be mount either a denial of service or code injection attack. Users are advised to turn off their wireless cards when not in use pending the availability of updates from Broadcom's partners.
The affected driver is bundled with new PCs from Dell, Gateway and HP among other computer manufacturers. Wireless card manufactures including Linksys also provide devices that ship with this driver. ...
