PHP/Webserver system user separation
Because after the switch to the packaged ownCloud the user that runs the php5-fpm processes is www-data, maybe a good idea would be to restrict it to only the directories that the application needs? I imagine that would be something like:
-
/tmp -
/usr/share/php5 -
/var/www/owncloud
Probably something else as well. That should prevent the ownCloud's www-data instance messing with other directories accessible by www-data user. Thoughts?
Sure, I always support the principle of least privilege. Maybe we could even create a owncloud user under which php could run? Or are you thinking about MAC or both?
Having a separate user for ownCloud PHP application would probably be best. Any owner/group changes needed for ownCloud to work, like /var/www/owncloud/data/ and similar could probably be handled by dpkg-statoverride.
dpkg-statoverride will only change single files and directories per line. Owncloud needs a lot of files and directories to have complicated owner permissions. Wouldn't it be easier to have a script to do this? There is also an official one.
@Polichronucci thanks for the hint. I guess the permission change script could be based on that.
With the script changing the permissions will work for both new and already existing installations. Alright I will try to implement this and let you know.
