Macworld's Jim Dalrymple reports that Apple today released a Security and AirPort update for Mac OS X to fix vulnerabilities in the company's wireless drivers.

According to Apple, the vulnerabilities were found in an internal audit of the software drivers, but are not open to any known exploits.

"The internal audit came as a result of claims by a senior researcher at SecureWorks that said he had revealed a vulnerability in Apple's MacBook wireless software driver that would allow him to take control of the machine," Dalrymple writes. "SecureWorks later clarified its position and said it had used a third-party driver and not Apple's driver."

Apple spokesman Anuj Nayar says SecureWorks never demonstrated any vulnerabilities in the Mac drivers. "They did not supply us with any information to allow us to identify a specific problem, so we initiated an internal audit," he says.

Still, Dalrymple's description of the vulnerability sounds a lot like the one SecureWorks found: "Two separate stack buffer overflows exist in the AirPort wireless driver's handling of malformed frames," he writes. "An attacker in local proximity may be able to trigger an overflow by injecting a maliciously crafted frame into a wireless network. When the AirPort is on, this could lead to arbitrary code execution with system privileges."

SecureWorks wouldn't comment for Dalrymple's article, but something tells me this isn't anywhere NEAR the end of the story...

UPDATE: Wi-Fi Planet's Eric Griffith has an excellent summary of the issues here.
