AirPort 4.2

CVE-ID: CAN-2005-2196

Available for: Mac OS X v10.3.3 through Mac OS X v10.3.9, and Mac OS X v10.4.2

Impact: Mobile users with the original AirPort Card enabled could automatically associate to an unsecure network.

Description: When not associated with a known or trusted network, the original AirPort Card connects to a randomly generated network with a default WEP key. This can allow mobile users to automatically associate with untrusted networks without warning. This does not affect AirPort Express Cards, which currently ship in systems. This update addresses the issue by selecting a randomly-generated 128-bit WEP key. Credit to Dino Dai Zovi for reporting this issue.
