Apple fixes 'killer text bomb' vulnerability with new update for iOS, macOS, watchOS, and tvOS

Apple released updates on Monday that will protect owners of iPhones, iPads, iMacs, MacBooks, iMac Pros, Apple Watches, and (phew!) Apple TVs from having toerags crash their devices.

The bizarre bug was in how Apple products handled a Unicode symbol representing a letter from the south Indian language of Telugu.

When, for instance, vulnerable versions of iOS displayed the character they would get their knickers in a twist, causing the app to crash.

Fortunately updating Apple operating systems is a pretty painless process.

For instance, on an iMac you just need to open App Store, and select Updates to see what updates are waiting to be installed.


On an iPhone or iPad, simply go to Settings > General > Software Update.

Go and grab iOS 11.2.6, watchOS 4.2.3, tvOS 11.2.6, and the macOS High Sierra 10.13.3 Supplemental Update now.
