Ubuntu Security Notice USN-1142-1
June 01, 2011

gdm vulnerability
==========================================================================

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

- Ubuntu 11.04

Summary:

GDM could be made to launch a browser and leak information about the system.

Software Description:
- gdm: GNOME Display Manager

Details:

Henne Vogelsang discovered that under certain PolicyKit configurations, GDM
could be made to launch a browser. A local attacker could exploit this to
gain access to files with the privileges of the gdm user. PolicyKit is not
configured in this manner in Ubuntu by default.

Update instructions:

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

Ubuntu 11.04:
  gdm                             2.32.1-0ubuntu3.2

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