23 March 2017
A security issue affects these releases of Ubuntu and its derivatives:
- Ubuntu 14.04 LTS

The problem can be corrected by updating your system to the following package versions:
To update your system, please follow these instructions: https://wiki.ubuntu.com/Security/Upgrades.
In general, a standard system update will make all the necessary changes.
