Does size matter?

Greetings, it's not my intention to send spam, despite the email's subject :) What I'm referring to is related to shellcode (or call it whatever you want) size; it's common knowledge -- or at least it used to be so, IMHO -- that it may be possible to experience size constraints while trying to overflow a buffer (just think about plain stack-based overflows without any kind of protection/mitigation techniques) so that one is unable to find enough space to store his fancy executable stuff... directly into the overflowable buffer. So I was just curious: does size really still matters nowadays or we have enough space to do whatever we want in order to execute our shellcode [1]? Are there any difference between OSes? (i.e. usually Windows apps offer (as a feature? :)) just enough space to do our job) TIA, bye Lorenzo [1] yes, syscall proxying and other cool methods could help us developing more complex shellcode without worring too much about size, but I was thinking about old shellcode contests where the winner was who had it more little (always shellcode buddies, always shellcode :)) -- Lorenzo Cavallaro `Gigi Sullivan' <sullivan () sikurezza org> Until I loved, life had no beauty; I did not know I lived until I had loved.
