How to fix?

Upgrade Debian:9 expat to version 2.1.1-2 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 Debian. See How to fix? for Debian:9 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.
