How to fix?

Upgrade Ubuntu:16.04 libgd2 to version 2.1.1-4ubuntu0.16.04.12+esm1 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream libgd2 package and not the libgd2 package as distributed by Ubuntu. See How to fix? for Ubuntu:16.04 relevant fixed versions and status.

In the GD Graphics Library (aka LibGD) through 2.2.5, there is a heap-based buffer over-read in tiffWriter in gd_tiff.c. NOTE: the vendor says "In my opinion this issue should not have a CVE, since the GD and GD2 formats are documented to be 'obsolete, and should only be used for development and testing purposes.'
