A patch ======= A patch could be to change create files with 0600 permissions rather than 0644 as done by [4]. However, that approach affects creation of non-temporary files too. In some cases, users may not want that behaviour -- you tell me.
There now is a patch in addition to [4] that people seeking to fix the described issue may be interested in. Dirk Meyer of FreeBSD brought my attention to a broken case with munpack that was shipped broken with the original 1.6 upstream tarball but may have been fixed by the removal of O_EXCL applied by earlier attempts to fix the insecure tempfile handling (as with FreeBSD). So with O_EXCL back in (or still in place), patch [5] can be used to repair munpack. Best, Sebastian
