Apple has released iOS 11.2.6 update to fix Telugu Unicode character bugs

Apple devices running iOS 11.2.5 are crashing and can also be bricked when a Telugu symbol is adopted by a third party app or when it is pasted into a native app like TextField, Label or Notes.

Apple has begun rolling out the 11.2.6 update for iOS, fixing a critical Telugu character bug that crashed into iPhones and iPads. The company is also introducing updates to watchOS, tvOS and macOS because the devices running on them were also affected by the bug. Weaknesses have plagued users since it was discovered, and once the news spreads, some people start using it by tagging the character in their tweets, posts and other social media platforms and crashing other people’s iPhones.

Devices affected by Telugu characters running iOS 11.2.5 and the latest update alleviates the problem. It also fixes minor issues where some third-party apps have failed to connect to external accessories. It was speculated that Apple would release the patch for vulnerabilities in the upcoming iOS 11.3, which is expected to fix the battery and performance issues of iPhones and is currently under beta testing. But an earlier report suggested that the company was already aware of the problem and was working on a solution, which would be released earlier.

To recall, it has recently been discovered that a Telugu Unicode character can force iPhone apps to crash, and in the worst case, a bootloop error. This happens even when it is sent as a message or even pasted into the textfield or label of the smartphone. Also, apps that crash because of the character need to be completely reinstalled from scratch.

If the Unicode symbol is received as a notification, it may restart the springboard. And if an iPhone is restarted during recovery, the device can enter a bootloop and be bricked. Reinstall the OS in Device Firmware Update (DFU) mode and flash the firmware on the smartphone. The bug has also affected Twitter, WhatsApp and other third party apps.
