Perbandingan Linux vs FreeBSD vs OpenBSD
linux (most of linux distribution):
Proteksi stack pake virtual address, randomize stack
handling overflow pakek SIGSEGV, stack bisa dioverwrite
mudah sekali bypass va
freebsd 6.1:
handling overflow pakek SIGSEGV, stack bisa di overwrite
bypass stack shield masih gagal coz i'm not freebsd user
openbsd 3.9:
handling overflow pakek SIGABRT, overflow di kill pakek sys_kill()
sulit sekali overwrite stack, proteksi non executable stack
it seems imposible to exploits stack overflow in openbsd

returning libc??sama kena SIGABRT

Ada yang mau kasih tambahan referense bypass proteksi stack
di mesin bsd. thx jika ada referensi
