Apple today released a security update for the AirPort Extreme base station. Firmware version 7.2.1 fixes the following: “Remote attackers may be able to adversely affect network performance.” This doesn’t sound too serious, but as always, every little security update ensures the overall security of your system and/or network.

For the more technically inclined:

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.

Whatever….

You can get the update by running AirPort Utility, which will detect the new firmware version and install it onto your AirPort Extreme base station.
