Ubuntu Security Notice (C) 2012-2013 Canonical, Inc. / NASL script (C) 2012-2013 Tenable Network Security, Inc.


Synopsis :

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

Description :

USN-1576-1 fixed vulnerabilities in DBus. The update caused a
regression for certain services launched from the activation helper,
and caused an unclean shutdown on upgrade. This update fixes the
problem.

We apologize for the inconvenience.

Sebastian Krahmer discovered that DBus incorrectly handled environment
variables when running with elevated privileges. A local attacker
could possibly exploit this flaw with a setuid binary and gain root
privileges.

Solution :

Update the affected dbus and / or libdbus-1-3 packages.

Risk factor :

Medium / CVSS Base Score : 6.9
(CVSS2#AV:L/AC:M/Au:N/C:C/I:C/A:C)
CVSS Temporal Score : 5.4
(CVSS2#E:POC/RL:OF/RC:C)
Public Exploit Available : true
