How to fix?

Upgrade Ubuntu:20.10 opensmtpd to version 6.6.4p1-1 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream opensmtpd package and not the opensmtpd package as distributed by Ubuntu. See How to fix? for Ubuntu:20.10 relevant fixed versions and status.

OpenSMTPD before 6.6.4 allows local users to read arbitrary files (e.g., on some Linux distributions) because of a combination of an untrusted search path in makemap.c and race conditions in the offline functionality in smtpd.c.
