Upload of OpenDocument files safe?

Hi dear tech folks,

The MediaWiki 1.18 release notes stated the following:

“(bug 24230 [1]) Uploads of ZIP types, such as MS Office or OpenOffice can
now be safely enabled. A ZIP file reader was added which can scan a ZIP
file for potentially dangerous Java applets. This allows applets to be
blocked specifically, rather than all ZIP files being blocked.”

On the Wikimedia Commons village pump [2], concerns were still raised about
security (some referred to macros specifically).

Brion stated in 2008 that the ZIP issue was the only problem we had with
OpenDocument upload [3], and TheDJ confirmed so in said thread; but let’s
make it super-extra clear as for the technical side:

* Is it completely safe to enable upload of OpenDocument files on Wikimedia
Commons?
* If not, would you advise us to restrict this type of uploads to trusted
users? [4]

With this confirmation, we can quietly discuss on Commons whether we want
this or not :-)

Thanks for your help!

Just a minor note on this point: we don't currently have any support
for per-group uploads. Ideally you would have some sort of array
with the key being the user right and the value(s) being the file
type(s) that you only want to allow for those users. This would leave
upload behavior unchanged for the rest of allowed filetypes.
