Apple Safari Webkit AIR Dangling Pointer Register

This strike exploits a vulnerability in Apple Safari Webkit. Specifically after optimizations are performed on AIR code, a register gets marked as late use and ultimately is determined to be a dead register and discarded. It may be possible for an attacker to construct Javascript in such a way that it is possible to control the data in this dangling register. This can cause a denial of service condition in the browser or potentially allow for remote code execution to occur.
