Another fault in Safari for the iPhone discovered

A new fault in Safari similar to the previous "TIFF" exploits has been discovered in the Safari browser of all firmwares.
It makes it possible to crash the application when executing a certain code.
At the moment it does not seem possible to do much else; however it may allow someone to jailbreak the iPhone as was possible with firmware 1.1.1.
But in that case, it would be the proof that one could exploit this fault and Apple would surely patch it quickly.
