How to fix?

Upgrade Ubuntu:16.04 libxrender to version 1:0.9.9-0ubuntu1+esm1 or higher.

NVD Description

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

The XRenderQueryFilters function in X.org libXrender before 0.9.10 allows remote X servers to trigger out-of-bounds write operations via vectors involving filter name lengths.
