Apple will fix the 'chaiOS' text message bug next week

A new flaw called "text bomb" has been discovered, affecting Apple's iPhone and Mac computers. Abraham Masri has shared a link on Twitter that can freeze a recipient's device, and possibly restart it, when sent in a text message.

The specially-engineered link is created to exploit a relatively new feature within the Messages app; the ability to preview web URLs within the chat. Worst of all, the harmful link will lead to a crash or freeze even if you leave it alone and never actually tap on it.

All users have to do is send a link to a web page hosting a piece of JavaScript code that attempts to send an SMS message.

Computer security expert Graham Cluley said: 'Something about the so-called ChaiOS bug's code gives your Apple device a brainstorm. Some users say their iMessage app didn't restart itself after it shut down and force-quitting wasn't an option. This renders the attack useless unless someone was to copy the code and post it on another platform to be disseminated again.

Pinnacle Ridge Processors Not Coming Next Month After All
The takehome message is that AMD has their act together and should deliver a steady cadence of updates for the foreseeable future. Because these new desktop APUs use a lot of the new features of the Pinnacle Ridge chips they require a new BIOS to work too.

As we reported yesterday, the chaiOS bug centres around a link that, when delivered, will stop the affected device in its tracks.

Like other Apple exploits in the past, the bug looks like a simple line of text or a link.

Apple hasn't yet commented on the flaw, but we will be sure to update this article if we hear more from the manufacturer.

Currently, the only solution appears is to quit the Messages app on iOS or Mac, open it back up, and immediately delete the entire message thread to restore full functionality. Until Apple releases a fix, users will simply have to hope their friends are nice people.
