it would just be another layer of indirection. the stack would still be treated the same and respond to the standard intel opcodes. now the operating system opcodes for system call and what not could be all changed around, but again, it's just a matter of time. it all depends on what is being exploited. if it is a buffer overflow, it depends where it occurs and how that data is handled. if you are emulating a sparc in a vm on an x86, the vm will respond to sparc shellcode. the best bet is running a firewall that defaults to deny everything, and then opening holes for the services you need to run after they have been properly secure. but remember, security is not, has not, and never will be absolute. it's about risk management and risk tolerance. btw, it would be slow as shit. -- christian void - [EMAIL PROTECTED] www.morphine.com/void/ gpg key available on request _______________________________________________ Bits mailing list [EMAIL PROTECTED] http://www.sugoi.org/mailman/listinfo/bits
