Apple - AirPort 4.2 [APPLE-SA-2005-07-19]


Hash: SHA1

APPLE-SA-2005-07-19 AirPort 4.2

AirPort 4.2 is now available and delivers the following security

Available for:  Mac OS X 10.3.3 to Mac OS X 10.3.9, and Mac OS X
CVE-ID:  CAN-2005-2196
Impact:  Mobile users with the original AirPort card enabled could
automatically associate to an malicious network
Description: When not connected to a known or trusted network, the
AirPort card "parks" on a randomly generated network with a default
WEP key.  This can allow parked AirPort cards to automatically
connect to malicious networks without warning.  This condition only
applies to AirPort cards and does not affect AirPort Extreme.  The
System Profiler utility can be used to indicate the type of AirPort
card installed.  This update addresses the problem by using a
randomly-generated 128-bit WEP key instead of the default WEP key.
Credit to Dino Dai Zovi for reporting this issue.
