You may have read that French article on ZDNet:

Something like a translation of this can be found here:

First thing to notice is that the article is not speaking in the name of the French department of defense. There should be some clarification soon.

Last week, I and some colleagues here in Hamburg had the opportunity to speak with Mr. Filiol, who is working on the internal security study about OpenOffice.org.

We talked about 3 different issues, but I can't talk about all details here.

One of the issues is simply a bug which we should fix soon. But it is not really a security issue, but more about how users trust certain kind of documents.

An other issue was about how our trust in installed macros might ease viral effects, and we talked about some interesting options here.

The last point was about integrity checks for documents, which can also give users some more security.

All together, I must say that it was really a good call, and that Mr. Filiol and his organization are really in favor of open source software. They like our short response time, which they probably won't have in some commercial products.
