Subject: [USN-144-1] dbus vulnerability

===========================================================
Ubuntu Security Notice USN-144-1	      June 27, 2005
dbus vulnerability
CAN-2005-0201
===========================================================

A security issue affects the following Ubuntu releases:

Ubuntu 4.10 (Warty Warthog)

The following packages are affected:

dbus-1

The problem can be corrected by upgrading the affected package to
version 0.22-1ubuntu2.1.  You have to restart your Gnome session (i.e.
log out and back in) after doing a standard system upgrade to effect
the necessary changes.

Details follow:

Besides providing the global system-wide communication bus, dbus also
offers per-user "session" buses which applications in an user's
session can create and use to communicate with each other.  Daniel
Reed discovered that the default configuration of the session dbus
allowed a local user to connect to another user's session bus if its
address was known. The fixed packages restrict the default permissions
to the user who owns the session dbus instance.

Please note that a standard Ubuntu installation does not use the
session bus for anything, so this can only be exploited if you are
using custom software which uses it.
