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

Ubuntu Security Notice (C) 2005-2016 Canonical, Inc. / NASL script (C) 2006-2016 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.

Note that Tenable Network Security has extracted the preceding
description block directly from the Ubuntu security advisory. Tenable
has attempted to automatically clean and format it as much as possible
without introducing additional issues.

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)
