You can now test if you're vulnerable to the more recently discovered
Microsoft and Intel problems.

If you're running Internet Explorer 4 on a Pentium, you can easily verify
for yourself that these problems exist by attempting to load this page --
but do save your work first. (Internet Explorer 3 is immune.)

This page automatically exploits both the recently-discovered Pentium bug,
and the recently discovered Explorer 4 res:// buffer overflow bug, via a
trivial piece of autoexecuting HTML -- which could easily be emailed.

Two orthogonal separate bugs combine to more than the sum of their parts;
emergent behaviour due to complexity in computer systems.
