Apple's Chinese Censorship Features Caused iPhone Crashing Bug

The bug enabled anyone to crash an Apple device by sending a text message with the Taiwanese flag

Any company that wants to do business in China has to abide by the draconian censorship laws imposed by the country's government.

Wardle explained how, due to a NULL pointer cockup, some iPhones that had set the U.S. as their default country would crash when receiving the flag or word as part of a text message, or when typing it. On Tuesday, security researcher Patrick Wardle illuminated another fix. He eventually found that the crashes were being caused by code that classified messages based on emojis they contained. English can still be set as the primary language, though.

As such, it would appear that Apple was forced to tweak its iOS 11 code to keep mentions of Taiwan out of its software and iPhone apps. He had no trouble reproducing the remotely triggerable bug, which crashed any iOS application that processed remote messages, including iMessage, Facebook Messenger, and WhatsApp. It helped to isolating the memory locations that stored a dereferenced null pointer and a faulty instruction that caused it. Wardle also relied on the iPhone's restore image to pull some of the code libraries.

Fans on the grounds of the All-England Club watch the World Cup quarterfinal between England and Sweden on their cellphones. I was out and about around the grounds and you could tell when England had scored and it was lovely, it was wonderful.

On an iOS device with CN (China) set as the language/locale, iOS is looking for the Taiwanese flag emoji and then removing it. On the side of the recipient, whenever an app would show the flag emoji, it would end up crashing. In the case of Taiwan, China's relationship with the territory is fraught at best.

A BUG in iOS 11.3 saw iPhones in China go to Borksville everytime the word "Taiwan" was written or the country's flag was used. China claims sovereignty over Taiwan, leading to a great deal of tension that extends even to emoji.

Luckily, that code won't cause a problem for non-Chinese iPhones anymore. The denial of service bug was live in iOS 11.3 and was seen affecting an iPhone 7 device, but, Apple has issued a fix with the iOS 11.4.1 update released just a few days ago.
