[Saumil] starts off off by packing the true exploit code into a picture. He demonstrates you could do this specifically, by encoding people of the code in the colour values with the pixels.

, but considering that that memory posture was written with info your system failed to anticipate, Then you really'll execute some code that shouldn't be there, and was loaded from the file...
