Apple yesterday released an update for its wireless-networking product, AirPort Extreme. Apple says AirPort Extreme Update 2007-02 improves compatibility with AirPort Extreme base stations and networks, as well as fixing a potential security hole.
Apple says the update improves compatibility for the MacBook Core 2 Duo and the MacBook Pro Core 2 Duo when using third-party access points configured to use WEP Open System security.
The AirPort update includes a fix for a security issue where attackers on the wireless network may cause system crashes. A security note on Apple's website says that an attacker in local proximity may be able to trigger a system crash by sending a maliciously-crafted frame to an affected system.
This security issue affects the Core Duo version of Mac mini, MacBook, and MacBook Pro computers equipped with wireless. Other systems, including the Core 2 Duo versions are not affected.
