An heap buffer overflow exists in the Apple AirPort wireless driver. Successful exploitation of this vulnerability may allow an attacker to execute arbitrary code, or cause a denial-of-service condition.
Apple AirPort drivers contain a heap buffer overflow in the code that handles scan cache updates. Note that the attacker needs to have 802.11 wireless connectivity to the vulnerable system to exploit this vulnerability.
Because device drivers execute with ring 0 privileges, this means that exploitation of device drivers can lead to full, unrestricted access to the vulnerable system.
An unauthenticated attacker may be able to execute arbitrary code with kernel (ring 0) privileges.
Apply updates from Apple
Disable the Affected Wireless Adapter
Turn your AirPort Card off when you're in situations where radio communication may be prohibited, such as in an airplane or at a hospital.
If you have disabled the AirPort port in Network preferences, then your AirPort Card is already turned off. To disable the AirPort port, choose Network Port Configurations from the Show pop-up menu and deselect the AirPort checkbox.
This vulnerability was reported in Apple Security Update 2006-005.
