I know there is a lot of other Apple news going on today. But if you’re reading on a Mac, iPhone, iPad, or Apple Watch (okay, the last one might stretch), then you should pause and update that device – today’s update addresses a security issue Apple has said may have. Being actively utilized
The updates, available in iOS / iPadOS 14.5.1, macOS 11.3.1, and watchOS 7.4.1 address the arbitrary code exploits built into WebKit, Apple’s framework at Shows most of the web content you see on your device. (Unless you’re using, say, Chrome or Firefox on a Mac) in normal language, the update fixes a vulnerability that allows malicious websites to run unselected code on your device, so it̵7;s not the type of update. Which you want to turn off
If you have an older device like an iPhone 5 or 6, an iPad Air, or a Mini 2 and 3, Apple also released iOS 12.5.3, which identified a WebKit bug.
If this story sounds a little familiar, it’s because there are two recent updates, iOS 14.4 and 14.4.2, which close similar security holes. Even if you don’t think you should update because you’re using a different web browser on your Mac or aren’t browsing the web on your Apple Watch (for obvious reasons), it’s still worth updating the device. Anything you may have – WebKit can run in unexpected locations and should not open security holes on your device, especially potentially exploited devices.
