Worms very seldom exploit O/S bugs - they're much more commonly based around
Application errors (buffer overflows, inappropriate privileges etc).
That's why people talk about worms affecting Apache, IIS, sendmail, wu-ftp
etc.
Viruses are simply code which runs under a particular operating system - just
another program - albeit one whose effects are not wanted by the owner of the
machine. The "trick" involved is to get the code to run, either by
exploiting human security weaknesses (eg: getting people to open what they
think is going to be a picture of nude tennis player), or by exploiting
application vulnerabilities (eg: getting M$ LookOut to auto-run a script when
someone simply previews an email.....)
