How to fix?

Upgrade Ubuntu:18.04 expat to version 2.1.1-1ubuntu1 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:18.04 relevant fixed versions and status.

Expat allows context-dependent attackers to cause a denial of service (crash) or possibly execute arbitrary code via a malformed input document, which triggers a buffer overflow.
