How to fix?

Upgrade Ubuntu:18.04 sqlite3 to version 3.22.0-1ubuntu0.3 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream sqlite3 package and not the sqlite3 package as distributed by Ubuntu. See How to fix? for Ubuntu:18.04 relevant fixed versions and status.

flattenSubquery in select.c in SQLite 3.30.1 mishandles certain uses of SELECT DISTINCT involving a LEFT JOIN in which the right-hand side is a view. This can cause a NULL pointer dereference (or incorrect results).
