Subject: viewvc security flaw?

I'm not sure about this one, I'm wondering if someone else has an opinion:

It was submitted as a Fedora security update, which I'm letting through for
now, as better safe than sorry.

To sum it up, it looks like the mime type used to display a given file in
viewvc can be set via the URL.  Obviously this means that an attacker could
force an arbitrary mime type on any file in a viewvc repository.

It strikes me as not crossing a trust boundary though, as I suspect you'd need
something malicious in the repo in order for this to really be useful.  If the
bad guys can already add arbitrary content, you have bigger problems.
