Packet Storm Exploit 2013-0903-1 - Apple Safari Heap Buffer Overflow

A heap memory buffer overflow vulnerability exists within the WebKit's JavaScriptCore JSArray::sort(...) method. The exploit for this vulnerability is javascript code which shows how to use it for memory corruption of internal JS objects (Unit32Array and etc.) and subsequent arbitrary code execution (custom ARM/x64 payloads can be pasted into the JS code). This exploit affects Apple Safari version 6.0.1 for iOS 6.0 and OS X 10.7/8. Earlier versions may also be affected. It was obtained through the Packet Storm Bug Bounty program.
