SWS Experiment no 3 (*UPDATED)

AIM - To Simulate the Buffer overflow attack.

#pragma check_stack(off)

#include <string.h>

#include <stdio.h>

void foo(const char* input)

{

   char buf[10];

 printf("My stack looks like:\n%p\n%p\n%p\n%p\n%p\n% p\n\n");

 strcpy(buf, input);

 printf("%s\n", buf);

printf("Now the stack looks like:\n%p\n%p\n%p\n%p\n%p\n%p\n\n");

}

void bar(void)

{

   printf("Augh! I've been hacked!\n");

}

int main(int argc, char* argv[])

{

   printf("Address of foo = %p\n", foo);

   printf("Address of bar = %p\n", bar);

   if (argc != 2)

       printf("Please supply a string as an argument!\n");

       return -1;

}
