==========================================================================

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

- Ubuntu 21.10
- Ubuntu 20.04 LTS

Summary:

libinput could be made to crash or expose sensitive information.

Software Description:

Details:

Albin Eldstål-Ahrens and Lukas Lamster discovered libinput did not properly
handle input devices with specially crafted names. A local attacker with
physical access could use this to cause libinput to crash or expose
sensitive information.

Update instructions:

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

and then log back in to make all the necessary changes.
