Here's the summary:

By allowing uploaded files to be run as code, any minor bug in the 
server or site software, anywhere, that could allow the uploading of 
arbitrary files could then ovewrite code that is run; this could then 
allow a much larger hack that could totally take over the site.

Ordinarily, code is not writeable by the webserver user, so any bug that 
allows the uploading of arbitrary files simply cannot overwrite code, 
and the impact is therefore minimized.

The reality is that the script kiddies are everywhere and always on the 
look out for these bugs, too.
