Package: adduser
Version: 3.47
Severity: critical
Justification: causes serious data loss
With kernel 2.4 and higher, one can use constructs such as
mount --bind /mnt/ftp/pub /home/user1/ftproot
I used that with proftpd to make files from different partitions
available to users inside their home. Just some minutes ago I managed to
wipe the mounted dir by doing a
deluser --remove-home
without the backup option installed and forgetting to umount the dir.
Of course, I should have been more careful. But it would have been
helpful if deluser had checked for mounted dirs in the user's home. A
simple "mount | grep $HOME" would be enough to issue a warning and
prompt for removal of each mounted dir.
/usr/local/sbin/adduser.local can be used to modify the local setup
after a user has been created. I used this file to mount the dir.
The same thing exists for deluser (/usr/local/sbin/deluser.local). While
it makes perfectly sense for adduser to allow only post-modification,
that is not enough for deluser. An additional file that gets executed
_before_ the actual removal of the user could be useful to ensure mounts
in the user's home get umounted before any harm is done.
