Detail

A security issue affects these releases of Ubuntu and its derivatives:

- Ubuntu 14.10 - Ubuntu 14.04 LTS - Ubuntu 12.04 LTS

Summary:

Several security issues were fixed in the X.Org X server.

Software Description: - xorg-server: X.Org X11 server - xorg-server-lts-utopic: X.Org X11 server - xorg-server-lts-trusty: X.Org X11 server

Details:

Olivier Fourdan discovered that the X.Org X server incorrectly handled XkbSetGeometry requests resulting in an information leak. An attacker able to connect to an X server, either locally or remotely, could use this issue to possibly obtain sensitive information. (CVE-2015-0255)

It was discovered that the X.Org X server incorrectly handled certain trapezoids. An attacker able to connect to an X server, either locally or remotely, could use this issue to possibly crash the server. This issue only affected Ubuntu 12.04 LTS. (CVE-2013-6424)

Update instructions:

The problem can be corrected by updating your system to the following package versions:

Ubuntu 14.10:
xserver-xorg-core 2:1.16.0-1ubuntu1.3

Ubuntu 14.04 LTS:
xserver-xorg-core 2:1.15.1-0ubuntu2.7
xserver-xorg-core-lts-utopic 2:1.16.0-1ubuntu1.2~trusty2

Ubuntu 12.04 LTS:
xserver-xorg-core 2:1.11.4-0ubuntu10.17
xserver-xorg-core-lts-trusty 2:1.15.1-0ubuntu2~precise5

After a standard system update you need to reboot your computer to make all the necessary changes.
