AirPort Extreme Base Station with 802.11n* Firmware
CVE-ID: CVE-2007-1338
Available for: AirPort Extreme Base Station with 802.11n*
Impact: AirPort Extreme Base Station with 802.11n* allows incoming IPv6 connections
Description: The default configuration of an AirPort Extreme Base Station with 802.11n* allows incoming IPv6 connections. This may expose network services on hosts connected through an AirPort Extreme Base Station with 802.11n* to remote attackers. This update addresses the issue by changing the default setting to limit inbound IPv6 traffic to the local network. This issue only affects AirPort Extreme Base Station with 802.11n*, and not other versions of the Base Station.
I think this may be significant if you have one of these models!
