tags 510744 + patch thanks This patch might be sufficient; it worked for me with trivial testing using the non-permissive D-Bus packages from <http://people.debian.org/~smcv/dbus-cve-2008-4311/>, but please test (you know what system-tools-backends does better than I do...)

commit fd648907e46017d46c367f59c62d0b0395830903 Author: Simon McVittie <http://smcv.pseudorandom.co.uk/> Date: 2009-01-04 19:35:51 +0000 Allow root to send messages to all the system tools backends, so they work even when CVE-2008-4311 has been fixed. Also disallow normal user access by destination, not by interface (fd.o #18961). diff --git a/system-tools-backends.conf b/system-tools-backends.conf index 00d6d58..537ef73 100644 --- a/system-tools-backends.conf +++ b/system-tools-backends.conf @@ -23,8 +23,8 @@ --> <!-- configuration modules can't be accessed directly... --> - <deny send_interface="org.freedesktop.SystemToolsBackends"/> - <deny send_interface="org.freedesktop.SystemToolsBackends.Platform"/> + <deny send_destination="org.freedesktop.SystemToolsBackends"/> + <deny send_destination="org.freedesktop.SystemToolsBackends.Platform"/> <deny send_destination="org.freedesktop.SystemToolsBackends"/> </policy> @@ -47,9 +47,18 @@ <!-- be able to speak to configuration modules, so any message to them has to go through the dispatcher --> - <allow send_interface="org.freedesktop.SystemToolsBackends"/> - <allow send_interface="org.freedesktop.SystemToolsBackends.Platform"/> <allow send_destination="org.freedesktop.SystemToolsBackends"/> + <allow send_destination="org.freedesktop.SystemToolsBackends.Platform"/> + <allow send_destination="org.freedesktop.SystemToolsBackends.GroupsConfig"/> + <allow send_destination="org.freedesktop.SystemToolsBackends.HostsConfig"/> + <allow send_destination="org.freedesktop.SystemToolsBackends.IfacesConfig"/> + <allow send_destination="org.freedesktop.SystemToolsBackends.NFSConfig"/> + <allow send_destination="org.freedesktop.SystemToolsBackends.NTPConfig"/> + <allow send_destination="org.freedesktop.SystemToolsBackends.ServicesConfig"/> + <allow send_destination="org.freedesktop.SystemToolsBackends.SMBConfig"/> + <allow send_destination="org.freedesktop.SystemToolsBackends.TimeConfig"/> + <allow send_destination="org.freedesktop.SystemToolsBackends.UserConfig"/> + <allow send_destination="org.freedesktop.SystemToolsBackends.UsersConfig"/> </policy> <policy group="stb-admin"> <!-- be able to speak to the dispatcher -->
