Apple has pushed out an update for the latest AirPort Extreme and Time Capsule base stations, and with it comes a fix for the Heartbleed vulnerability. Apple has confirmed the fix in a statement, saying those with the older generation need not update.
The update is firmware 7.7.3 for the base stations debuted last summer -- those running the applicable device should update. Said Apple in a statement to the folks at Macworld:
"The firmware update provides a fix for the recent OpenSSL vulnerability for the latest generation of 802.11ac enabled AirPort Extreme and AirPort Time Capsule base stations (June 2013). This vulnerability only impacts recent Airport devices that have the Back to My Mac feature enabled. Customers with previous generation AirPort Extreme and AirPort Time Capsules do not need to update their base stations."
For those who need to update, users should use the AirPort Utility for Mac or iOS -- AirPort Utility 6.3.1 or higher for those on Mac OS X, or 1.3.1 or higher for those using iOS. The tool is available from Apple's support website.
