Apple releases Heartbleed bug fix for 2013 AirPort Extreme and Time Capsule

Apple has released a bug fix patch for its 2013 AirPort Extreme and Time Capsule, fixing the OpenSSL ‘Heartbleed’ vulnerability. The update does not apply to the AirPort Express.

Firmware update 7.7.3 is recommended for all AirPort Extreme and AirPort Time Capsule base stations with 802.11ac. It provides security improvements related to SSL/TLS. Other AirPort base stations do not require this firmware update.

Amusingly, when Heartbleed made headlines earlier this month, Apple said that no key software or services were affected. They conveniently forgot to mention that their latest router hardware was susceptible to the flaw.

Broadcom just announced its next round of portable device wireless chip, the BCM4335, which includes the ability to connect to the superfast 802.11ac networks. Apple exclusively uses Broadcom chips in this family for its iOS devices (and a different family for its Macs). The current iPad and iPhone use the Broadcom BCM4330 802.11a/b/g/n baseband/radio with integrated Bluetooth 4.0+HS and an FM transceiver—and the xxx5 is just a minor step up.

We found some code that indicates the next iPhone will use the Broadcom BCM4334, which adds the 40nm process and Wi-Fi Direct capabilities (perhaps opening some Airdrop capabilities too).

The 40nm chip will continue to deliver Bluetooth 4.0 and FM, but its 802.11ac networking could save some power using the new standard. It also features the “industry’s most advanced idle power consumption performance, which significantly extends a mobile device’s battery life.”

Sample chips are already available with a full production expected to be delivered in Q1 2013, just in time for next year’s iPads.
