Quite a bit of confusing and a vast amount of information coming from
all directions about the WMF 0day. Here are some URL's and generic facts
to set us straight.
The "patch" by Ilfak Guilfanov works, but by disabling a DLL in Windows.
So far no problems have been observed by anyone using this patch. You
should naturally check it out for yourselves but I and many others
recommend it until Microsoft bothers to show up with their own patch.
Ilfak is trusted and is in no way a Bad Guy.
You can find more information about it at his blog:
http://www.hexblog.com/2005/12/wmf_vuln.html
If you are still not sure about the patch by Ilfak, check out the
discussion of it going on in the funsec list about the patch, with Ilfak
participating:

Occasional information of new WMF problems keep coming in over there.
In this URL you can find the best summary I have seen of the WMF issue:
http://isc.sans.org/diary.php?storyid=994
by the "SANS ISC diary" team.
In this URL you can find the best write-up I have seen on the WMF issue:

By Matthew Murphy at the "Securiteam Blogs".
Also, it should be noted at this time that since the first public
discovery of this "problem", a new one has been coming in - every day.
All the ones seen so far are variants of the original and in all ways
the SAME problem. So, it would be best to acknowledge them as the
same... or we will keep having a NEW 0day which really isn't for about 2
months when all these few dozen variations are exhausted.
A small BUT IMPORTANT correction for future generations:
The 0day was originally found and reported by Hubbard Dan from Websense
on a closed vetted security mailing list, and later on at the Websense
public page. All those who took credit for it took it wrongly.
Thanks, and a better new year to us all,
Gadi.
