Buffer Overflow Attacks:

Craft a buffer attacking input to make:

(a) pass value to be -12

(b) execute hidden_func()

C program:

\#includestdio.h int func1() \{ printf("executing func1() "); return 1; \} int hidden_func( ) \{ printf("executing hidden_func () ") ); \}. int func2() \{ signed short pass =0; char arr[12]; gets(arr); printf("pass:\%d ", pass); puts (arr); return 0; \} int main () \{ func2(); return 0 ; \}
