At least for the x86 architecture, working ASCII-only shell code exists (even shell code which consists just of letters!). See for example: http://cert.uni-stuttgart.de/archive/vuln-dev/2000/10/msg00200.html ASCII-only shellcode for RISC platforms is even harder and might be impossible. -- Florian Weimer [EMAIL PROTECTED] University of Stuttgart http://CERT.Uni-Stuttgart.DE/people/fw/ RUS-CERT fax +49-711-685-5898 ---------------------------(end of broadcast)--------------------------- TIP 3: if posting/reading through Usenet, please send an appropriate subscribe-nomail command to [EMAIL PROTECTED] so that your message can get through to the mailing list cleanly
