Apple Safari WebKit hoistSloppyModeFunctionIfNecessary Improper Object Validation

This strike exploits a vulnerability in Apple Safari Webkit. Specifically the vulnerability exists in the BytecodeGenerator::hoistSloppyModeFunctionIfNecessary method. It is possible to craft Javascript in such a way that allows for an object to be passed as the property variable directly as a string to the op_get_direct_pname handler without being properly validated. This can lead to a denial of service in the browser application or potentially allow for remote code execution to occur.
