rhythmbox vulnerability
==========================================================================

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

- Ubuntu 12.04 LTS
- Ubuntu 11.10

Summary:

Rhythmbox could be made to run programs as your login when using the Context
plugin.

Software Description:
- rhythmbox: music player and organizer for GNOME

Details:

Hans Spaans discovered that the Context plugin in Rhythmbox created a
temporary directory in an insecure manner. A local attacker could exploit
this to execute arbitrary code as the user invoking the program. The
Context plugin is disabled by default in Ubuntu.

Update instructions:

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

Ubuntu 12.04 LTS:
  rhythmbox-plugins               2.96-0ubuntu4.1

Ubuntu 11.10:
  rhythmbox-plugins               2.90.1~20110908-0ubuntu1.4

After a standard system update you need to restart Rhythmbox to make all
the necessary changes.
