You can download an update from Intel.Last night, Intel and the SANS Internet Storm Center announced three Centrino vulnerabilities that can also be used to take over computers using Centrino-based wireless cards.
On Wednesday afternoon at the Black Hat computer security conference in Las Vegas, hackers Jon "Johnny Cache" Ellch and Dave Maynor plan to demonstrate how to take over any Apple MacBook if its wireless card is turned on, even if the owner is not connected to a wireless network.
The vulnerabilities apparently can also be found in Centrino-based laptops as well.
Summary:
Security vulnerabilities exist in the Microsoft* Windows* drivers for the Intel® 2200BG and 2915ABG PRO/Wireless Network Connection Hardware because of the way that they currently handle certain frames. An attacker could potentially exploit these vulnerabilities which could potentially lead to remote code execution and system control.
