Question

How does a heap overflow attack work?

a.

Programs receive data of an unexpected length and copy it into a buffer that's too small to contain it, causing the program to overwrite whatever it is that follows the heap block in memory.

b.

Programs receive data of an expected length and copy it into a buffer that's too small to contain it, causing the program to overwrite whatever it is that follows the heap block in memory.

c.

Programs receive data of an unexpected length and copy it into a buffer that's large enough to contain it, causing the program to overwrite whatever it is that follows the heap block in memory.

d.

Programs receive data of an expected length and copy it into a buffer that's large enough to contain it, causing the program to overwrite whatever it is that follows the heap block in memory.
