Firmware Update 7.1 for AirPort Extreme Base Station with 802.11n

The firmware update for the Airport Extreme base station 802.11n fixes 2 vulnerabilities

- 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.
- Filenames on a password-protected AirPort Disk may be viewable to users on the local network
Description: AirPort Disk is a feature of AirPort Extreme Base Station with 802.11n that allows the sharing of files from a USB hard drive connected to a compatible base station. Sharing options, including password protection, are available via the AirPort Disk Utility. An issue in the AirPort Disk feature allows users on the local network to view filenames (but not their contents) on a password-protected disk without providing a password. This update addresses the issue by performing additional validation on AirPort Disk access requests. This issue only affects AirPort Extreme Base Station with 802.11n*, and not other versions of the Base Station.

You will need a recent version of AirPort Utility (at least 5.1) for performing this firmware update; for additional information please read: http://docs.info.apple.com/article.html?artnum=305366
