How to fix?

Upgrade Ubuntu:16.04 expat to version 2.1.0-7ubuntu0.16.04.5 or higher.

NVD Description

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

In libexpat before 2.2.8, crafted XML input could fool the parser into changing from DTD parsing to document parsing too early; a consecutive call to XML_GetCurrentLineNumber (or XML_GetCurrentColumnNumber) then resulted in a heap-based buffer over-read.
