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.
This is an unknown exploit as for as Apple is concerned. However, as with all security updates, you should jump in early to make sure you are not left vulnerable. You can use the software update to snag the update.
