'ChaiOS' Bug Can Cause IMessage to Crash With a Text Message

There's a new bug floating around called "chaiOS" that appears to be a basic GitHub link. However, when you text it to a person via the iMessage app (whether on iOS or MacOS), it will crash the app and possibly cause the device to freeze and restart. In other words: Be aware that this exists, but don't send it to anyone.

It was Twitter user Abraham Masri who first uncovered the bug. The people over at 9to5Mac tested it out, and it certainly messed up their devices. They reported crashes and severe lags as a result of the bugs that persisted until the thread containing the link was deleted from the iMessage app. If you did send or receive it, and your device is a mess, there's also a fix in the replies to Masri's original tweet. We've reached out to Apple to confirm that their team is aware of the bug, and to see if there are any fixes in the works.

        Fuck twatter. Fortunately we can recover the link https://web.archive.org/web/20180117063656/https://iabem97.github.io/chaiOS/ [archive.org]

        No guarantees but fingers crossed. Apparently the thing is meta property="og:title" content=some funny stuff which goes on for a bit.

          Interestingly, in Pale Moon 26.5 on Fedora, it causes the browser is use 100% CPU for very long periods of time. Grabbing it with curl, it's just a 12MB file.

          $ curl 'https://web.archive.org/web/20180117063656/https://iabem97.github.io/chaiOS/' | wc -c

    This is a "working" link:
    https://web.archive.org/web/20180117063656/https://iabem97.github.io/chaiOS/ [archive.org]

    The document contains a meta property="og:title" content=$FOO
    with FOO a 4 MB string with a bunch of non-ASCII chars.
    Might be a buffer overflow.
