This exploit is a 0day code execution exploit for Apple Safari 4.0.5. It is a memory corruption vulnerability that can be exploited by using the parent.close() function. The exploit code contains a Windows Execute Command (calc) shellcode. It can be used both locally and remotely, provided that the POPUP must be enabled [Ctrl+Shift+K]. The exploit code contains a JavaScript code that creates an array of 1000 elements, each containing a block of memory with the shellcode. It then uses the parent.close() function to trigger the memory corruption.
