network-manager-applet vulnerability
============================================================================

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

- Ubuntu 11.10
- Ubuntu 11.04
- Ubuntu 10.04 LTS

Summary:

network-manager-applet could create insecure AdHoc wireless networks.

Software Description:
- network-manager-applet: GNOME frontend for NetworkManager

Details:

USN-1483-1 fixed a vulnerability in NetworkManager by disabling the
creation of WPA-secured AdHoc wireless connections. This update provides
the corresponding change for network-manager-applet.

Original advisory details:

 It was discovered that certain wireless drivers incorrectly handled the
 creation of WPA-secured AdHoc connections. This could result in AdHoc
 wireless connections being created without any security at all. This update
 removes WPA as a security choice for AdHoc connections in NetworkManager.

Update instructions:

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

Ubuntu 11.10:
  network-manager-gnome           0.9.1.90-0ubuntu6.1

Ubuntu 11.04:
  network-manager-gnome           0.8.4~git.20110318t152954.9c4c9a0-0ubuntu1.1

Ubuntu 10.04 LTS:
  network-manager-gnome           0.8-0ubuntu3.1

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