Our Advanced Windows Exploitation (AWE) live course in Columbia, Maryland is fast approaching with a start-date of October 24. Not only is the first time we have offered this training outside of BlackHat, it is also the first time we are able to offer a full 5 days of training and a limited number of seats are still available for this intense course.

The reduceRight method executes a user defined callback function once for each element present in the array. As you can make the array point out of bounds, the attacker can pass a fake sprayed object address to the callback function. At this point code execution can be gained in different ways triggering a method of the fake object.
Code execution on Windows 7 obviously requires some fun playing with pointers and memory to bypass DEP and ASLR protections, both of which this exploit manages to do.
