How does iPhone Messages app crash work?
Basically, the message shown here contains lots of text. When it’s loaded by iOS, it freezes the app. As you close the app and reopen it, iOS again tries to fetch the message and fails. Thus, the exploit works on the principle that iOS always tries to open the most recently opened text.

This is done by overloading the vCard, which is used to exchange contact information, with lots of data. The exploit uses a contact with about 14,281 lines of code, which is about 70 times the code found in an average vCard.
In his blog post, the hacker has detailed the exploit and instructions. If you’re willing to give it a try, do so at your peril.
