You could try Open Office at
http://www.openoffice.org/ for a free, open source alternative to Microsoft Office. I use this at home, and I haven't noticed any real problems with it for my purposes at home. At work, it's a little different, and I do have Microsoft Office there. But work also decided to block incoming Word attachments temporarily until some workaround to this hole can be put in place. Interestingly enough, I've heard that there is no exploit for the hole, either in the wild or proof of concept, so currently, no damage can be done. *shrug* I don't know if that's true though, I only heard about the existence of the hole.
