This is base-audit-0.4 on FreeBSD 12.2 - but it affects other FreeBSD versions
as well.

This is partly related to
https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=245878

When kernel and userland do not match, false positives result.  Case in point,
this host is:

$ freebsd-version -u -k
12.2-RELEASE-p1
12.2-RELEASE-p2
$ 


When running the script:

[dan at tallboy:~] $ sudo /usr/local/etc/periodic/security/405.pkg-base-audit 

Checking for security vulnerabilities in base (userland & kernel):
Host system:
Database fetched: Sat Dec 12 16:51:55 UTC 2020
0 problem(s) in 0 installed package(s) found.
FreeBSD-12.2_2 is vulnerable:
OpenSSL -- NULL pointer de-reference
CVE: CVE-2020-1971
WWW:

1 problem(s) in 1 installed package(s) found.


This false positive also arise from jails.
