Ubuntu Security Notice USN-2275-1
July 08, 2014

dbus vulnerabilities
==========================================================================

A security issue affects these releases of Ubuntu and its derivatives:

- Ubuntu 14.04 LTS
- Ubuntu 13.10
- Ubuntu 12.04 LTS

Summary:

Several security issues were fixed in DBus.

Software Description:
- dbus: simple interprocess messaging system

Details:

Alban Crequy discovered that dbus-daemon incorrectly sent AccessDenied
errors to the service instead of the client when enforcing permissions. A
local user can use this issue to possibly deny access to the service.
(CVE-2014-3477)

Alban Crequy discovered that dbus-daemon incorrectly handled certain file
descriptors. A local attacker could use this issue to cause services or
clients to disconnect, resulting in a denial of service. (CVE-2014-3532,
CVE-2014-3533)

Update instructions:

The problem can be corrected by updating your system to the following
package versions:

Ubuntu 14.04 LTS:
  dbus                            1.6.18-0ubuntu4.1
  libdbus-1-3                     1.6.18-0ubuntu4.1

Ubuntu 13.10:
  dbus                            1.6.12-0ubuntu10.1
  libdbus-1-3                     1.6.12-0ubuntu10.1

Ubuntu 12.04 LTS:
  dbus                            1.4.18-1ubuntu1.5
  libdbus-1-3                     1.4.18-1ubuntu1.5

After a standard system update you need to reboot your computer to make all
the necessary changes.
