This Text Can Crash, Reboot Any iPhone Quickly

A recently found bug in Apple’s mobile OS implies that anybody can efficiently crash another individual’s iPhone, or send it into Safe Mode if jailbroken, by merely sending a SMS or iMessage containing a specific set of non-Latin characters. The bug, as found by a number of keen-eyed Reddit users, triggers an iOS device to immediately crash and reboot upon receiving of the message, as long as the device isn’t really opened in the very same conversation thread in which the message was received.

As you might expect, the rather unusual and tough to find bug has actually been spreading around the Internet like wildfire since its discovery with people trying to crash and hang the iPhones of good friends and family all over the globe.

With no main statement on the bug from Apple it’s challenging to determine exactly what the precise concern is, but it appears to be dued to the way that iOS has actually been developed to handle and render Arabic text. And given that iOS is embraced on the iPhone, iPad and iPod touch, all of those devices are most likely impacted when receiving a message of this nature through the native Messages app.

When an incoming message is shown through Apple’s built-in banner alert notice system, or perhaps straight on the lock screen if the device is locked, iOS makes an attempt to abbreviate the scripted message with an ellipsis as is standard when attempting to reduce text in a container that isn’t big enough to show the entire string. Nevertheless, it appears that if the ellipsis is put in the middle of non-Latin script characters, such as Arabic or Chinese, it triggers an internal mistake and forces the system to crash and reboot each time.

The string of text itself is as follows:

لُلُصّبُلُلصّبُررً ॣ ॣh ॣ ॣ

Due to the fact that of the really certain nature of the text string that is in fact needed to be received by the device prior to a crash will happen, it’s highly unlikely that this will certainly take place simply as an accident. With that said, there are a number of workarounds to resolve a restarting device if the problem does take place.

If the Messages app is resumed straight to the upseting conversation then simply sending out a reply to the message will certainly fix the issue. Additionally, users can also utilize Siri to send a text message or an image from Photos app Share Sheet to the sender to solve the concern.

Meanwhile jailbroken users can install this .deb file using iFile to fix the issue.

Here are some key realities which Reddit user that_c00l_kidhas actually laid down:

It’s definitely a weird bug and one that we will likely see an official response by Apple in the near future. In the mean time, if you get a text that causes this crash then it’s highly likely that it’s from a good friend playing a prank.
