File permissions.secure of Package permissions
# /etc/permissions.secure # # Copyright (c) 2001 SuSE GmbH Nuernberg, Germany. All rights reserved. # # Author: Roman Drahtmueller <draht@suse.de>, 2001 # # # See /etc/permissions for general hints on how to use this file. # # /etc/permissions.secure is designed for the use in a multi-user and # networked installation. Most privileged file modes are disabled here. # Many programs that still have their suid- or sgid-modes have had their # security problems in the past already. # The primary target of this configuration is to make the basic things # such as changing passwords, the basic networking programs as well as # some of the all-day work programs properly function for the unprivileged # user. The dial-out packages are executable for users belonging to the # "dialout" group - therefore, these users are to be treated "privileged". # Packages such as (remote-) batch queueing systems, games, programs for # the linux text console, everything linked against OOP libraries and # most other exotic utilities are turned into unprivileged binary files # in order for them not to cause any security problems if one or more of # the programs turn out to have buffer overruns or otherwise locally # exploitable programming errors. # This file is not designed to make your system as closed and as restrictive # as at all possible. In many cases, restricted access to a configuration # file is of no use since the data used can be obtained from the /proc file # system or interface configuration as well. Also, system programs such as # /sbin/ifconfig or /sbin/route are not changed because nosey users can # bring their own. "Security by obscurity" will add any significant # security-related advantage to the system. Keep in mind that curiosity # is a major motivation for your users to try to see behind the curtain. # # If you need the functionality of a program that usually runs as a # privileged user, then use it as root, or, if you are not root, ask your # system administrator for advice. In many cases, adding a user to the # "trusted" group gives her access to the resources that are not accessible # any more if the admin chose to select "secure" as the permissions default. # # Please make use of the diff program to see the differences between the # permissions.easy and permissions.secure files if things don't work as # they should and you suspect a permission or privilege problem. # The word "easy" is a reference for the /etc/permissions.easy file. # # As usual, these settings are "suggested". If you feel so inclined, # please feel free to change the modes in this files, but keep a log # of your changes for future reference. # Please always keep in mind that your system listens on network sockets # in the default configuration. Change this by disabling the services that # you do not need or by restricting access to them using packet filters # or tcp wrappers (see hosts_access(5)) to gain a higher level of security # in your system. # # Directories # # no lock files for emacs: /var/lib/xemacs/lock root:trusted 1775 # for screen's session sockets: /var/run/uscreens root:root 1777 # # /etc # /etc/crontab root:root 600 /etc/exports root:root 644 /etc/fstab root:root 644 /etc/ftpaccess root:root 644 /etc/ftpusers root:root 644 /etc/inetd.conf root:root 644 /etc/inittab root:root 644 /etc/mtab root:root 644 /etc/rmtab root:root 644 /var/lib/nfs/rmtab root:root 644 /etc/syslog.conf root:root 600 # # suid system programs that need the suid bit to work: # /bin/su root:root 4755 # disable at and cron for users that do not belnong to the group "trusted" /usr/bin/at root:trusted 4750 /usr/bin/crontab root:trusted 4750 /usr/bin/gpasswd root:shadow 4755 /usr/bin/newgrp root:root 4755 /usr/bin/passwd root:shadow 4755 /usr/bin/chfn root:shadow 4755 /usr/bin/chage root:shadow 4755 /usr/bin/chsh root:shadow 4755 /usr/bin/expiry root:shadow 4755 # the default configuration of the sudo package in SuSE distribution is to # intimidate users. /usr/bin/sudo root:root 4755 /usr/sbin/su-wrapper root:root 0755 # opie password system # #66303 /usr/bin/opiepasswd root:root 4755 /usr/bin/opiesu root:root 4755 # "user" entries in /etc/fstab make mount work for non-root users: /usr/bin/ncpmount root:trusted 4750 /usr/bin/ncpumount root:trusted 4750 # #331020 /sbin/mount.nfs root:root 0755 # mount/umount have had their problems already: /bin/mount root:root 4755 /bin/umount root:root 4755 /bin/eject root:audio 4750 # # #133657 /usr/bin/fusermount root:trusted 4750 # #66203 /usr/lib/majordomo/wrapper root:daemon 4750 # glibc backwards compatibility /usr/lib/pt_chown root:root 4755 /usr/lib64/pt_chown root:root 4755 # needs setuid root when using shadow via NIS: # #216816 /sbin/unix_chkpwd root:shadow 4755 /sbin/unix2_chkpwd root:shadow 4755 # qpopper /usr/sbin/popauth pop:trusted 4750 # from the squid package /usr/sbin/pam_auth root:shadow 4755 # still to be converted to utempter /usr/lib/vte/gnome-pty-helper root:tty 2755 # # mixed section: most of it is disabled in this permissions.secure: # ######################################################################### # rpm subsystem: /usr/src/packages/SOURCES/ root:root 755 /usr/src/packages/BUILD/ root:root 755 /usr/src/packages/RPMS/ root:root 755 /usr/src/packages/RPMS/alpha/ root:root 755 /usr/src/packages/RPMS/alphaev56/ root:root 755 /usr/src/packages/RPMS/alphaev67/ root:root 755 /usr/src/packages/RPMS/alphaev6/ root:root 755 /usr/src/packages/RPMS/arm4l/ root:root 755 /usr/src/packages/RPMS/athlon/ root:root 755 /usr/src/packages/RPMS/i386/ root:root 755 /usr/src/packages/RPMS/i486/ root:root 755 /usr/src/packages/RPMS/i586/ root:root 755 /usr/src/packages/RPMS/i686/ root:root 755 /usr/src/packages/RPMS/ia64/ root:root 755 /usr/src/packages/RPMS/mips/ root:root 755 /usr/src/packages/RPMS/ppc/ root:root 755 /usr/src/packages/RPMS/ppc64/ root:root 755 /usr/src/packages/RPMS/powerpc/ root:root 755 /usr/src/packages/RPMS/powerpc64/ root:root 755 /usr/src/packages/RPMS/s390/ root:root 755 /usr/src/packages/RPMS/s390x/ root:root 755 /usr/src/packages/RPMS/sparc/ root:root 755 /usr/src/packages/RPMS/sparcv9/ root:root 755 /usr/src/packages/RPMS/sparc64/ root:root 755 /usr/src/packages/RPMS/x86_64/ root:root 755 /usr/src/packages/RPMS/armv4l/ root:root 755 /usr/src/packages/RPMS/hppa/ root:root 755 /usr/src/packages/RPMS/hppa2.0/ root:root 755 /usr/src/packages/RPMS/noarch/ root:root 755 /usr/src/packages/SPECS/ root:root 755 /usr/src/packages/SRPMS/ root:root 755 ######################################################################### # video /usr/bin/v4l-conf root:video 4750 # Itanium ia32 emulator /usr/lib/ia32el/suid_ia32x_loader root:root 0755 # scotty: # #66211 /usr/bin/ntping root:trusted 4750 # This is not extensively tested. /usr/bin/vlock root:shadow 0755 /usr/bin/Xorg root:root 0711 # turned off write and wall by disabling sgid tty: /usr/bin/wall root:tty 0755 /usr/bin/write root:tty 0755 # thttpd: sgid + executeable only for group www.
