The update fixes a vulnerability, which was disclosed in November as part of the Month of Kernel Bugs campaign, that affects both the server and client versions of Mac OS X, Apple said in its alert. Apple described the worst case scenario as: "An attacker in local proximity may be able to trigger a system crash by sending a maliciously-crafted frame to an affected system." The issue only affects the Intel Core Duo-based versions of Mac mini, MacBook and MacBook Pro computers equipped with wireless. Apple fixed the issue by adding more validation of wireless frames, the Cupertino, Calif., company said. The AirPort Extreme Update 2007-001 may be obtained from the Software Update feature in Mac OS X or Apple's Software Downloads Web site.
