GREAT NEWS!

The vBulletin.com user alexm has managed to re-compile the uploader.swf file with this exploit (and another) fixed!
He has uploaded a new .zip file with a new uploader.swf file to the post I linked to above.
This file is a direct replacement for uploader.swf and you can upload it over your current uploader.swf file and go back to the flash uploader!
Warning: alexm admits he is not a flash developer and there is no guarantee additional exploits don't exist- but it looks good to me.
