Apple issues critical update, iOS 16.0.3

This update is for all iPhones since the iPhone 8 up to the present iPhone 14 series. You should update immediately.

Translated into English: some bad guys figured out how to disable your iPhone through a “maliciously crafted email message,” which means that someone found a way to mess up your iPhone by sending an email message that triggered your iPhone into wasting time on nonsense, and not doing what you wanted. A “denial-of-service attack” is a type of computer device attack that basically has your computer, or phone in this case, stop doing useful things as the computer is constantly distracted into doing useless things. It is the equivalent of someone coming and ringing your doorbell all the time, forcing you to check the door and — there isn’t anyone there.

Update immediately. And if you have an iPhone 8 or later and are not running iOS 16, you should do so immediately.
