it's a known issue that the intel x86 platform is vulnerable to stack-based buffer overflow exploits. the amd64 architecture is addressing this by providing hardware page protection which prevents code from being illegally executed off the stack. netbsd has enabled this feature by default in netbsd 2.0. i look at the x86 platform like training wheels and amd64 like a nice racing bike... ;-)
