"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.

Note that Tenable Network Security has extracted the preceding
description block directly from the Ubuntu security advisory. Tenable
has attempted to automatically clean and format it as much as possible
without introducing additional issues."
