Question

How can an attacker defeat stack checking?

a.

By overwriting the area in the stack where parameters were passed to the function

b.

By using a specially crafted buffer to overwrite the memory address used for returning values to the caller

c.

By figuring out an address to write to in memory that would allow them to run their own code before the process is terminated by the stack-checking code

d.

All of the above

Answer: (d).All of the above Explanation:Attackers can defeat stack checking by overwriting the area in the stack where parameters were passed to the function, using a specially crafted buffer to overwrite the memory address used for returning values to the caller, and figuring out an address to write to in memory that would allow them to run their own code before the process is terminated by the stack-checking code.
