iPhone Bug Causes Certain Text Message To Crash Phone

A bizarre bug has just been revealed by a Reddit user in which a certain specific text message will cause the iPhone messenger app to crash and subsequently cause the phone to reboot.

The actual problem here is a bug in Apple’s CoreText code, which, when given a certain set of unicode values, ends up referencing an invalid memory area, which results in a crash. You can read more here:

It will be interesting to see how fast Apple patches this problem, as it seems that now that the bug has gone viral many pranksters are setting out to wreak havoc on their friends.  It also appears that the “poison” message will crash other apps that it is located in.  The full extent of the problems has not been fully documented yet, however most Reddit users playing around with the message are experiencing problems themselves.  So, sending the message to someone will sometimes crash the senders phone as well as the receivers.

The bug has also been replicated on other devices that run iOS, such as the Apple watch.
