Since the information on the missing patch was removed in the advisory, we as users only know that there's a critical vulnerability in WMP out there that's still unpatched, and have no workaround or precautions to take beyond simply not using WMP.
Thanks for putting out the word - and for the attribution!
Edit - BTW re: the linked article in your blog - I've seen MPLAYER2 on the system, but never messed with it. Looks like it could do nicely for those who like Windows player but don't want all the crapola the later versions throw in..
