Just a question, what's to stop anyone from copying their own ld.so to ~/
and using it? What I mean is, isn't the problem in the kernel and not
glibc (where fs options should be enforced just like read and write
perms)? Even going to the kernel, nothing stops someone from copying an
executable to their local ~/ and adding +x and then executing it. So
basically, the only thing noexec really cures is +s, and even then should
still be the fs (i.e. kernel) that enforces it.
