I know it's been 7 years since this video, but one thing I never saw anyone mention was that it combines right to left and left to right text in one message. When trying to shorten a message, the phone sets the text direction to left to right with the English words, but half way through it switches to right to left with Arabic text. That means it was probably trying to shorten the Arabic text backwards and causing some kind of crash trying to delete text out of bounds if the intended memory address.

Jeff Bobbery​ its the notification that truncates the text and the string length of the truncation is longer than expected when its truncated. The string exceeds the amount of characters expected using their standard truncation method. The way that works is some Arabic gets longer when you take off characters as tom explained. Chances are text string that receives the text writes the extra characters where they don't belong. In programming when that happens the application crashes, the application that runs the notifications is the OS... So crash

I can imagine a loop of repeatedly adding and removing a character, and testing for length, attempting to iterate to a suitable length. Or getting a negative number for how much length adding a character contributed where only positive numbers are supposed to occur.

TripleDz The Arabian Peninsula is only in the East relative to Europe, but in the West relative to about half of the Earth's population (China + India). By your logic, is Christianity, a religion born in the desert lands of Arabia, something Eastern, or something Western? It's all relative. Hell, if you're judging by the formally defined hemispheres of the Earth, 95% of Europe is in the Eastern Hemisphere. And as far as cultures, Arabic has been one of the most influential ones on the entire world I'm not talking about the recent spread of Islam through the world, rather about the influence that Arabic cultures and languages have had on the rest of the world, and Europe in particular, for millennia. My point to all of this is: Does it matter where it's from? Being one of the most spoken languages in the world, I'd say that exactly where the person who invented it is kind of irrelevant.

I'm betting a combination of the mixed languages and weird resizing makes the phone inadvertently walk off the end of the character array, which usually - but not always - causes a segmentation fault. Occasionally it didn't blow up because there just happens to be valid text or a termination character in that next memory location.

Once you mentioned deleting text, I knew where you were going with Arabic, it all clicked into place. This has to be one of the most plausible explanations I've heard.

Regarding your question about the Arabic script pattern you found, yes that comes up in almost every word as the way we connect letters can make the letters appear a different size for certain letters such as ت as you showed.

I used to have an article in my files (from Scientific American, I think...) about rendering text on computers. They discussed Arabic (lots of ligatures plus context-sensitive letter forms) and Devanagari, where letters aren't always in the order you would expect. I can see the combination of the two causing all sorts of trouble.

I have learned more from you than a day at Computer coding class.

Your accent and tone of voice makes everything you say sound like the most important thing in the world. I enjoy it.

What if when it cuts Arabic text, the method enters some weird infinite recursive loop trying to shorten the text, but every time a character is removed, the method preforming the task returns possibly an infinite amount of sub-strings -- containing a message of the same size or larger? If the case, Apple could have a safety precaution within the OS's kernel that limits the amount of iterations a single task or thread has within a certain amount of time, which causes the phone to reset.

What you described in arabic are essentially ligatures, there are a lot of them in arabic. Works just the same way as Æ &AE. I would think that it should not be a problem to cut one of those as they are saved as 2 digits but just displayed with ligatures. I think it may be an issue with reading direction. Arabic is right to left so it would make sense to cut the beginning of the string rather than the end. But the other characters in may have some oddities in reading direction as well which create a conflict.

I forgot to tell you that we at apple devs say thank you for doing our debugging for us. We didn't even have to do any work. We watched this and tested the issue. Bang on. Thanks

Also consider that the phrase contains a combination of left-to-right and right-to-left text. That, combined with text that is not widely understood by English only speaking developers likely contributes to the bug... (disclaimer: Pure Speculation)

As an Egyptian (Who speaks and texts in Arabic) the interesting part is that we send a lot of text messages everyday, in Arabic, and I don't recall any of my friends with iPhones complaining about how each time they receive a text, their phone crashes and restarts. My speculation is that the problem is in those diacritics, you see, "أهلا وسهلا" (Arabic for "Hello and welcome") can also be written like this "أهْلًا وَسَهْلًا", we usually use the former form, as it is easier and faster to write than the latter, also those weird characters after the Arabic letters (Which means nothing in Arabic, by the way) are to blame, diacritics are placed above and under the letter, usually. but when there is no letter to be attached to, that pretty circle sometimes substitute that letter and if the software isn't ready to deal with that situation, I honestly don't know what would happen, example (" ً َ ُ ً ً ّ ٌُ ٌُ ًْ" ).

Some tests that can verify this hypothesis: You can send messages that have arabic words that, when characters are deleted, are actually smaller. Than you can compare it with words that get bigger if some characters are deleted (different from the text you show on the video). If the first don't crash and the second does, it is one evidence more that your hypothesis might be correct

Excellent work.. I wonder if rearranging the string or using a similar arrangement would also cause the problem? It seems by your explanation that it should reproduce under similar, but different circumstances.

Your thinking makes sense, it's interesting. I wish I wasn't an Android guy so I could try this one out. I've seen tons of "how do I fix" and "why does it work", but one thing I haven't heard yet is how this was discovered...

I suspect you're onto something, Tom. I'm not sure the buffer grows with any truncation of that specific text - but sometimes it doesn't shrink and stays the same length. Perhaps there are two distinct bits of code for evaluating how many characters to render (one for UI and one for saving/sending to other notification bits? doesn't matter why, so long as there's two methods). If one method was to count backwards, removing characters until it fits, and another method were to count forward saving the index of the last character that fit - then you could end up in a situation where you get a buffer of memory that has, say: 30 characters in it, and then try to render 35 characters out of that buffer. It would only crash once in awhile where the memory after the 30th character is protected, say: owned by another application.

What is Tom's job and why does he have knowledge about such varied things? I think I saw a linguistics thing once but then he said he only speaks one language.

Good analysis. The first letter in my name س is longer at the end of the word than in the beginning or middle سـ.

It happen in everyday Arabic writing, though it is only short in sight, it is not like another version of the letter, and you can't get two letters by cutting one word :) it is still the same length (depend on the font). also, the word on screen meant nothing :) it was basically "DTAT"

Hey Scott, have you tried testing your hypothesis?

Alternatively you could try to construct another message with the bare minimum needed to create the crash. It would probably take some time, but if you do manage to crack it you'll get quite a bit of traffic from the various news sites. Apple bugs get a lot of attention ;)

From sky news - The problem arises due to a glitch in the way Arabic text is rendered in banner notifications. Apple's software attempts to abbreviate the text with an ellipsis, which causes the system to crash and the phone to reboot.

I do a lot of kernel edits on OSX and iOS, oddly this bug works with the desktop as well because the notifications in the upper right uses the same style of shortening. At least on my hackintoah I don't have imessage active lol I got a call from a friend who works with iPhone software a lot because he has been scratching his head regarding this. From what I have notices with the bug is how Arabic does the characters exactly as you said. The only bandaid for this issue that I can find for apple to do is change how the ellipse gets place on any language, is after a work not in the middle. As someone who reads Japanese having an ellipse in between two kanji you could easily have the text short hand say something different that the actual message.

Confirmed working when sent from Windows Phone :) My friends hate me now.

people tried sending it to me back then. they were quite disappointed when they found out that I didn't have an iPhone 😂

It could also have to do with mixing the direction of the text in a single string. I've run into issues with that before.

I did a lot of experimenting with this bug and what I found was that the arabic symbols didn't matter. Its was all in the effective power. When this bug was out you were able to send Objective C commands through iMessage and have the command execute on the other persons phone. Effective power was a command that tested the battery and turned your phone off.

Ok it's been several years. What's the answer?

Facebook messages and twitter have blocked that text combination. This makes me sad :(

But you can still use it in Microsoft team :D

when someone does this to you. Can you see the text on your phone? so you know who sent it. Or does it not show it and you have know idea what just happened and who did it?

Please do an update to the new effective power!! :)

It didn't do anything when it was texted to me lol I just got really confused

So how did anyone come up with this anyways? Just some random messing around?

probably someone who knew something about how apple's push notifications work and came up with an idea to make it freak out. like how @derGeruhn discovered arbitrary code execution in tweetdeck by using a heart emoji.

Loved the video... as always :)

I remember this 😂. I would mess with my family with that text because we all (the other 2 that lived with me) had the same phone, a 5c (we now have the same Motorola phone now but that doesn't really matter). It was amazing to see the phone restart with just a text.

My guess was similar. You have english text going from left to right, and arabic from right to left. An elipses must go in there, but the phone doesn't know where, and it crashes. My friends think it's ISIS for some reason

wow! you actually do know Arabic basics :O impressed

Interesting point, but also check the shapes above or below the letters, they also play a role, for example the "Fat-ha" as in َت or "Kasra" as in تِ , which changes how the letter is pronounced ( َت = Ta while تِ = Te ) , these shapes are treated as letters, so when it tries to shorten them the screen space used by the sentence isn't actually shortened or changed, so if it has a certain amount of characters that can fit in a bubble notification, then it might be calculating the letter count of the sentence without these shapes in mind, yet trying to shorten it with them in mind, resulting in a text that doesn't fit the criteria of a bubble message that crashes the UI and triggers a reboot, maybe?

It's interesting seeing people trying to understand Arabic. It's such a complex language and is extremely difficult to learn. And yes there are words like the ones you mentioned

Is it fixed? What was the problem and solution?

Oh, that code stuff is almost definitely what went wrong,, but why would it have such catastrophc consequences? Some variations could get as bad as brick the phone, not just crash the app.

because notifications are not an app but in the OS itself. If an app crashes, it just closes. But if the OS crashes, the whole device crashes (unless you expected that it could crash and handle that accordingly).

An OS is made of components, it's possible for one to crash without the whole OS crashing, if it's not a vital component. And even then, the worst that should happen is the OS has to be restarted, not that it dies.

***** I understand respringing, but that's only the best case for this. It could also brick the whole phone.

this video is INCREDIBLY old by now but my theory is those diacritics, plus the arabic shortning/lengthening thing is the cause. the diacritics are showing with the dotted circle - that circle is a placeholder. that character is a standalone diacritic, but it's displaying the placeholder symbol too. i think the bug arises from the phone trying to figure out what it needs to do with the letter/word associated with the diacritic, but of course, there _is_ no associated letter

Did anyone ever find out what the answer was? Maybe there was a report.

Instead of gaming with my friends on friday, I watch your video's on friday!

A simple solution to this would be to implement the shortening in a way where the text is simply rendered further offscreen instead of using ellipses. That way the iPhone wouldn't have to cut the word short, the text would simply fade out off the edge of the banner notification. Think about that, +Apple.

Jonah Safern It's from the Captain America Civil War movie, It is a series of words that force the Winter Soldier into submission.

Reminds me of the old chickHEN exploit used to jailbreak PSPs back in the day... you'd have to load a certain image file which would cause the console to "crash" and launch CFW but it only worked sometimes and was very unstable.

I think it is because when the phone is trying to cut the text shorter it compresses the message but then since there are more charaters that may be able to fit on the screen the phone tries to add the letter again but doesn't have enough space on the screen then makes an infinite loop of cutting and adding letters and that crashes the phone and it may not always work because of the size of the phone witch changes how many characters that there are.

The real question is how the f they found out that this text crashes a iphone
