Potential Security Vulnerability Exposed in iPhone

A few weeks ago at the CanSecWest security conference Charlie Miller walked away with the Pwn2Own prize for successfully compromising a fully patched Mac OS X system in a matter of seconds. Miller is making headlines again with the announcement that he has discovered that it is possible to trick the iPhone into running shellcode and expose it to attack. The ability to run shellcode essentially allows an attacker to do whatever they want to do within the iPhone operating system. Previously it has been thought that shellcode could only run on iPhones that had already been hacked or 'jailbroken' in some other way.
