Overwriting Function Pointers

For this example, look at the overflow- 2 folder. Inside this folder, you’ll notice the following C code.

Similar to the example above, data is read into a buffer using the gets function, but the variable above the buffer is not a pointer to a function. A pointer, like its name implies, is used to point to a memory location, and in this case the memory location is that of the normal function. The stack is laid out similar to the example above, but this time you have to find a way of invoking the special function(maybe using the memory address of the function). Try invoke the special function in the program. 

Keep in mind that the architecture of this machine is little endian!
