I'm not sure about this one, I'm wondering if someone else has an opinion: http://viewvc.tigris.org/issues/show_bug.cgi?id=354 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. -- JB
