Consider the following program with a buffer overflow vulnerability. The program is executed with input passed in via the command line, from an attacker 1: int foo (char arg) char buf [16]; strncpy (buf, arg, 32); return 0; 10: int main (int argc, char argv[]) 12: 13: 14: 15: 16: 17: char string[12]; strncpy (string, arav 11, 12) foo (argv[2]) return 0 Which buffer should the attacker overflow, and which function's saved Return Address should they target
