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

- Ubuntu 11.04
- Ubuntu 10.04 LTS

Summary:

NetworkManager could create insecure AdHoc wireless networks.

Software Description:

Details:

It was discovered that certain wireless drivers incorrectly handled the
creation of WPA-secured AdHoc connections. This could result in AdHoc
