A new bug has been discovered in the Messages app, allowing a string of characters sent to a person via iMessage or SMS to crash an iPhone and cause the Messages app to crash after being opened. The bug, which requires a specific string of symbols and Arabic characters to be sent.
The bug is related to the Messages app and the notification system used by iPhone and iPad devices and appears to work only if there is iPhone to iPhone communication.When the user receives the message, he is not able to reopen the Messages app without reboot the mobile device. The only way to stop the problem is to get the sender of the malicious text message to send another message or wait for someone else to send a new one.
Since the string of characters is so specific, most users are unlikely
to stumble across the bug.The sting that crashes the iPhone is" Power

However, there are several workarounds that can undo the damage. The effect can be undone by sending another message (any normal text) to the person who sent you the malicious string, canceling out the initial strand.
Another option is to send the person who sent the the string a message using the share sheet by simply pressing the "share" button in other apps, or send yourself a message via Siri, or ask Siri to "send a message" to whoever sent it.
