Ubuntu 4.10 : dbus vulnerability (USN-144-1)

Ubuntu Security Notice (C) 2005-2013 Canonical, Inc. / NASL script (C) 2006-2013 Tenable Network Security, Inc.


Synopsis :

The remote Ubuntu host is missing one or more security-related patches.

Description :

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.

Solution :

Update the affected packages.

Risk factor :

Low / CVSS Base Score : 2.1
(CVSS2#AV:L/AC:L/Au:N/C:P/I:N/A:N)
