Ubuntu Security Notice USN-1483-1
June 27, 2012

network-manager vulnerability

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

- Ubuntu 11.10
- Ubuntu 11.04
- Ubuntu 10.04 LTS


NetworkManager could create insecure AdHoc wireless networks.

Software Description:
- network-manager: Network connection manager


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:

Ubuntu 11.04:
  network-manager                 0.8.4~git.20110319t175609.d14809b-0ubuntu3.1

Ubuntu 10.04 LTS:
  network-manager                 0.8-0ubuntu3.3

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