Finding buffer overflows • Hackers find buffer overflows as follows: • Run web server on local machine. • Issue requests with long tags. All long tags end with “$$$$$”. • If web server crashes, search core dump for “$$$$$” to find overflow location. • Some automated tools exist. (eEye Retina, ISIC). Preventing buf overflow attacks • Main problem: • strcpy(), strcat(), sprintf() have no range checking.
