How to fix?

Upgrade Debian:10 libxml2 to version 2.9.4+dfsg1-3.1 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream libxml2 package and not the libxml2 package as distributed by Debian. See How to fix? for Debian:10 relevant fixed versions and status.

A flaw in libxml2 allows remote XML entity inclusion with default parser flags (i.e., when the caller did not request entity substitution, DTD validation, external DTD subset loading, or default DTD attributes). Depending on the context, this may expose a higher-risk attack surface in libxml2 not usually reachable with default parser flags, and expose content from local files, HTTP, or FTP servers (which might be otherwise unreachable).
