USN-1483-1: NetworkManager vulnerability
Ubuntu Security Notice USN-1483-1
27th June, 2012
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.
- 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.
The problem can be corrected by updating your system to the following package version:
- Ubuntu 11.10:
- network-manager 0.9.1.90-0ubuntu5.2
- Ubuntu 11.04:
- network-manager 0.8.4~git.20110319t175609.d14809b-0ubuntu3.1
- Ubuntu 10.04 LTS:
- network-manager 0.8-0ubuntu3.3
To update your system, please follow these instructions: https://wiki.ubuntu.com/Security/Upgrades.
After a standard system update you need to reboot your computer to make
all the necessary changes.
