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

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.

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.
