The desktop team recently discovered a flaw in dbus-glib where it didn't respect the "access" flag on properties specified. Basically, core OS services like NetworkManager which use dbus-glib were specifying e.g. the "Ip4Address" as read-only for remote access, but in fact any process could modify it.
I have a patch for dbus-glib (attached). However, due to the nature of the way
dbus-glib works where at build time services generate a C data structure from
XML and embed it into their binary, affected services will need to be rebuilt
(though not patched).
This affected list is for F-12; I think for RHEL5 we just need dbus-glib and NetworkManager.
KNOWN AFFECTED SERVICES:
* DeviceKit-Power
* NetworkManager
* ModemManager
KNOWN NOT AFFECTED that claim to handle org.freedesktop.DBus.Properties:
* ConsoleKit (it denies all Properties access using dbus policy)
* gdm (ditto)
* PackageKit (all of the properties on exposed GObjects are G_PARAM_READONLY)
KNOWN NOT AFFECTED (because I audited them)
* gnome-panel (no dbus properties)
* gnome-system-monitor (ditto)
PROBABLY NOT AFFECTED
* hal (doesn't claim to handle org.freedesktop.DBus.Properties)
* polkit (uses eggdbus)
* rtkit (doesn't use dbus-glib)
* DeviceKit-disks (all its properties appear to be readonly)
* wpa_supplicant (doesn't implement Properties)
* upstart (doesn't use dbus-glib)
