According to CNET news.com and other sources, there is a security vulnerability in the handling of WMF images in versions of Openoffice.org up to 2.0.4. The latest version, 2.1, does not have this vulnerability. Users of versions previous to 2.1 can install and use 2.1, or get a patch from openoffice.org. In a brief visit to the site I was not able to find the patch. I have already, however, installed version 2.1 on our iMac, and that’s probably the best course of action for users, and the easiest to do once you are visiting the Openoffice.org web site.
