Subject: Should a non-root user always be able to mount on a directory they do not own if /etc/fstab entry is marked "user"
Date: Thu, 24 Nov 2005 20:11:49 -0600 [thread overview]
Message-ID: <438672E5.1080202@austin.rr.com> (raw)
Should a non-root user always be able to mount on a directory they do
not own if /etc/fstab entry is marked "user"? Are there other
restrictions that I should check?
In particular, bug
https://bugzilla.samba.org/show_bug.cgi?id=1617
asks the cifs vfs allow that a user can mount over a directory owned by
root if /etc/fstab says "user" on the matching line.
If there are not other security problems, I was planning to follow the
suggestion in the bug? I noticed that at least for this version of
SuSE smbfs no longer can do setuid mounts, so I could not compare with
that, but presumably nfs has no particular security checks in mount
beyond what is already there in mount.cifs.c (with the suggested
modification)
