Brief Hands-On Report--Apple released Firmware 7.2.1 for AirPort Extreme "n" Base Stations

Apple released Firmware 7.2.1 for AirPort Extreme "n" Base Stations and it is available for installation via AirPort Utility or as a stand-alone file from this Apple Web page. According to the Read Me file,

The AirPort Extreme Base Station with 802.11n* and Firmware 7.2.1 is Wi-Fi certified for 802.11n draft 2.0. This update also includes bug fixes and security updates.

The details of the security fix are:

CVE-2007-2242--Remote attackers may be able to adversely affect network performance. A design issue exists in the IPv6 protocol's handling of type 0 routing headers. Depending on network topology and capacity, the reception of specially crafted IPv6 packets may lead to a reduction in network bandwidth. This update addresses the issue by disabling the support for type 0 routing headers. This issue does not affect the Gigabit Ethernet version of AirPort Extreme Base Station with 802.11n*.

We installed the firmware update via AirPort Utility. No problems were encountered during installation nor in the performance of our AirPort Extreme "n" Base Station afterward. [Bill Fox & Dana Baggett]
