Here's the vulnerable C code snippet:

#include

void malicious$\_$function$()\{$

printf$("$Malicious function executed!

$")$;

$\}$

void $(*$func$\_$ptr$)()$;

void vulnerable$\_$function$()\{$

$//$ Vulnerability: Overwriting func$\_$ptr with malicious$\_$function's address

func$\_$ptr $=$ malicious$\_$function;

$\}$

int main$()\{$

$//$ Call vulnerable function

vulnerable$\_$function$()$;

$//$ Indirect function call through func$\_$ptr

func$\_$ptr$()$; $//$ Potential security risk if func$\_$ptr is pointing to malicious$\_$function

$//$ Rest of the program

return $0$;

$\}$

With CFI enabled, describe in detail how it prevents the attack and ensures the control flow integrity.
