Tech news: iOS 11.2.1, tvOS 11.2.1 Updates Now Available to Download, Restore HomeKit Sharing.

Apple is rolling out iOS 11.2.1 update for eligible
iPhone, iPad, and iPod touch devices, as well as tvOS
11.2.1 update for the Apple TV, both of which restore
HomeKit sharing after a remote access bug was spotted
last week. iOS 11.2.1 is now available to download for
iPhone 5s and later, iPad Air and later, and iPod
touch 6th generation. tvOS 11.2.1 is available for
Apple TV 4 and 4k variants.
The reason for a simultaneous software update is
because it restores HomeKit for shared users, a
feature that was recently disabled due to a bug that
was spotted last week. This bug was responsible for
giving unauthorised access in vulnerable circumstances.
With the new updates, for both platforms, Apple has
promptly restored access for all users. In its release
notes, Apple says, "iOS 11.2.1 fixes bugs including an
issue that could disable remote access to shared users
of the Home app."
The security bulletin that accompanied the updates
reveals that HomeKit bug allowed a remote attacker to
unexpectedly alter application state, and that the
message handling issue was addressed with improved
input validation.
iPhone, iPad, and iPod touch users can download this
update by going into Settings > General >
Software Update and checking for the update.
Once it appears, click on Download and Install;
the update will automatically get installed on the
device. It is advisable to use a Wi-Fi connection to
download the over-the-air update. Also, you should
back up your data, and ensure that your device has
over 50 percent of charge or connected to a power
source before beginning the update process.

On your Apple TV, the update can be installed in a
similar manner by going into Settings > System >
Software Updates in tvOS. Once downloaded, the
update will restart the Apple TV once. Do note that
tvOS 11.2.1 is available on the Apple TV 4K over the
air only. On the Apple TV 4, although, you can install
the update manually by downloading the IPSW file
through iTunes.
Just last week, iOS 11.2 was rolled out to all eligible
Apple iPhone, iPad, and iPod users. This major
update brought new features like support for Apple
Pay Cash and faster wireless charging support. tvOS
11.1 was also updated last month but brought minimal
upgrades to the Apple TV.
