From Bugzilla Helper:
User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:0.9.9) Gecko/20020528
Description of problem:
When using a entry from /etc/mailcap, Mozilla apparently only uses the command
name, and ignores the rest of the command line.
Version-Release number of selected component (if applicable):0.9.9-13
Steps to Reproduce:
1.Add an entry "image/x-xwindowdump; xwud -in %s" in /etc/mailcap
assuming no other configuration for this content-type.
2.Point mozilla to a file with an .xwd suffix.
Actual Results: Mozilla first asks if it should use xwud to display this file.
If accepted, another window is quickly flashed, and then gone.
Expected Results: A new xwud window with the contents of the xwd file.
Apparently, Mozilla invokes "xwud <file>" omitting the "-in" in the mailcap entry.
I hesitated a bit before categorising this as a security bug. It could be a
security issue if mailcap consists an entry like "gv -safer %s", where the
mozilla behaviour would effectively remove the -safer flag. In the end I
decided to call it a security issue, reasoning it is easy to downgrade it if
Is this still a problem in 1.0.1?
Yes, I still see this with mozilla 1.0.1-10.
(Is it something I should report upstream maybe?)
I checked upstream. Not surprisingly, it was already reported there.
This is being fixed (eventually) upstream so will mark this closed.
