A new exploit will either lock up your iPhone or iPod Touch or crash your Safari browser on your PC or Mac OS desktop if you simply visit a maliciously coded Web site. Unlike an earlier exploit that required users to click to become infected, the new code published by iPhoneWorld requires no user interaction.
So far, Apple has had no comment.
The code was first reported in January and exhausts the memory in Safari, which in turn will cause your iPhone or iPod Touch to freeze, or your desktop Safari to crash. "Given the nature of this issue," said the BugTraq newsgroup vulnerability report, "remote code execution may also be possible, but this has not been confirmed."
