ldm vulnerability
==========================================================================

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

- Ubuntu 11.10
- Ubuntu 11.04

Summary:

LTSP Display Manager could be made to run programs as an administrator.

Software Description:
- ldm: LTSP display manager

Details:

Tenho Tuhkala discovered that the LTSP Display Manager (ldm) incorrectly
filtered keybindings. An attacker could use the default keybindings to
execute arbitrary commands as root at the login screen.

Update instructions:

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

Ubuntu 11.10:
  ldm                             2:2.2.4-0ubuntu1.1

Ubuntu 11.04:
  ldm                             2:2.2.1-0ubuntu1.1

After a standard system update you need to restart the LTSP Display Manager
to make all the necessary changes.
