Agreed, every single workd that I cited, and most of the words furtheron
in your message that I didn't cite.

But you claimed before that buffer overflows are no vital problem if they
can't create a root exploit, and I told you that in my world, buffer
overflows are a vital problem even for non-root.

Yes, root exploits are bad... root can do everything evil to a machine,
including reading vital data. But you don't need root to read vital data,
you only need the id that owns them.
