"Apple on Thursday released a Security and AirPort update for Mac OS X that fixes vulnerabilities found in the company’s wireless drivers. Apple said the issues found were the result of an internal audit of the software drivers and that no known exploits exist for the issues addressed in this update.
The internal audit came as a result of claims by a senior researcher at SecureWorks that said he had revealed a vulnerability (http://www.macworld.com/news/2006/08/17/wirelesshack/index.php) in Apple’s MacBook wireless software driver that would allow him to take control of the machine. SecureWorks later clarified its position and said it had used a third-party driver and not Apple’s driver.
Apple has maintained that SecureWorks has provided no proof that Mac drivers are vulnerable in any way."
