How to fix?

Upgrade Ubuntu:16.04 libxfixes to version 1:5.0.1-2ubuntu0.1~esm1 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream libxfixes package and not the libxfixes package as distributed by Ubuntu. See How to fix? for Ubuntu:16.04 relevant fixed versions and status.

Integer overflow in X.org libXfixes before 5.0.3 on 32-bit platforms might allow remote X servers to gain privileges via a length value of INT_MAX, which triggers the client to stop reading data and get out of sync.
