Description Dan Williams 2009-12-10 03:08:50 UTC
+++ This bug was initially created as a clone of Bug #546115 +++ nm-connection-editor may inadvertently publish network configuration settings over D-Bus when a user changes those settings using the connection editor. D-Bus gives all clients a bus name (usually 1:XXX where XXX is an ever-increasing number) whenever the client connects to the bus. Even though this client is not exporting a /named/ service, it is still on the bus and if the client exports an object (even inadvertently, without registering a well-known bus name) signals emitted by that object will also be proxied onto the bus. nm-connection-editor inadvertently exported connection objects on the bus, and when a user changes those connections though the connection editor GUI, the editor may emit a summary of those changes onto the bus, leading to the information disclosure. 1) start 'dbus-monitor --system' in a terminal 2) run nm-connection-editor 3) edit a connection that has secrets, like a protected wifi network 4) Upon clicking the "Apply" button, check the dbus-monitor terminal window; the wifi network password may have been emitted as part of the "Updated" signal for that connection This is only a problem for NM 0.7.x present in Fedora <= 11 and RHEL5. The problem has been long corrected in NM 0.8 (F12+). Upstream commit to 0.7.x fixing this problem is here: http://git.gnome.org/cgit/network-manager-applet/commit/?h=NETWORKMANAGER_APPLET_0_7&id=8627880e07c8345f69ed639325280c7f62a8f894
