Yet you stated, unequivocally and without restriction:
In the case of OSX and iOS, PDFs are usually read by native, non-Adobe, routines built into the OS... so they are not at risk either...
Sorry, the jailbreakme.com (and in fact, the new jailbreaking of the iPhone 4) site relied on on ACEs. They exist and are exploited every day by the thousands.
That you continue to deny this is simply amazing...
So you are wrong. Now the question is: Will you admit it?
iOS has been - and is being - cracked by simple ACE exploits daily. Bone-stock iOS loads are cracked - jailbroken - by using arbitrary code execution exploits. Your constant lies to the contrary notwithstanding! ACEs are how you jailbreak a phone, but that goes against your "all-things-Apple-are-invulnerable" approach, so of course you cannot admit it.
Continue in your lying ways, Sword!
Not any more... the vulnerability used by Jailbreakme.com was closed four weeks ago. It no longer works. Admit it. Your claim that they are being "exploited every day by the thousands" is not true.
