A Debian bug report [1] noted that a security fix was committed to widelands [2]. The commit log is quite vague, but it looks as though it might be an arbitrary file overwrite vulnerability, judging by the code changes.

I've prepared a rebase to Widelands "build16", which includes the fix for this, I'm going to push this as an update to all supported Fedora releases.
Fantastic. Thank you, Hans.
build16 is in Fedora now, so this can be closed.
