AirPort Base Station Firmware Updates 7.6.9 and 7.7.9

By Agen G. N. Schmitz

Apple has released firmware updates for AirPort Extreme and AirPort Time Capsule base stations with 802.11ac Wi-Fi (the tower-like models receive Firmware Update 7.7.9), as well as older AirPort Express, AirPort Extreme, and AirPort Time Capsule models with 802.11n Wi-Fi (Firmware Update 7.6.9). Both updates patch the KRACK exploit (see “Wi-Fi Security Flaw Not As Bad As It’s KRACKed Up To Be,” 17 October 2017), improving the handling of state transitions to prevent reusing a nonce (aka, Number ONCE, an arbitrary number that can only be used once) in WPA multicast/GTK clients. Update 7.7.9 also addresses a memory corruption issue that enabled an attacker within range to be able to execute arbitrary code on the Wi-Fi chip. You must update your AirPort base station using AirPort Utility on your Mac or an iOS device with the free AirPort Utility app installed (the download isn’t available via the Apple Support Web page or Software Update). (Free, release notes for 7.6.9, release notes for 7.7.9)
