The Ubuntu 14.10, Ubuntu 14.04 LTS, and Ubuntu 12.04 LTS operating systems have been updated in order to fix a number of X.Org X server vulnerabilities identified by devs.

A series of X.Org X server issues have been found by developers and the Ubuntu team has been quick to issue a patch that corrects most of the problems that have been marked.

"Ilja van Sprundel discovered a multitude of security issues in the X.Org X server. An attacker able to connect to an X server, either locally or remotely, could use these issues to cause the X server to crash or execute arbitrary code resulting in possible privilege escalation," is noted in the security advisory.

For a more detailed description of the problems, you can see Canonical's security notification. Users are advised to upgrade their systems as soon as possible, especially since this is a complicated core component and it needs a lot of attention.

In general, a standard system update will make all the necessary changes. As you can imagine, it's mandatory to reboot the system.

You can also use the terminal to update the system. Just enter these commands in a terminal near you:

code
sudo apt-get update
sudo apt-get dist-upgrade
