Description Josh Bressers 2009-01-06 20:04:18 UTC

The following issue was reported to us from Manuel Reimer:

https://bugs.freedesktop.org/show_bug.cgi?id=19377

The basic summary, is that xdg-open detects the file mime type, and Firefox gets its mime type from the server.  That means that a malicious site could trick a user into thinking they are downloading a PDF file, but could be treated differently by xdg-open.
