Ubuntu Security Notice USN-1483-2
June 27, 2012
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.
