How to fix?

Upgrade Alpine:3.12 rsyslog to version 8.1908.0-r1 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream rsyslog package and not the rsyslog package as distributed by Alpine. See How to fix? for Alpine:3.12 relevant fixed versions and status.

contrib/pmdb2diag/pmdb2diag.c in Rsyslog v8.1908.0 allows out-of-bounds access because the level length is mishandled.
