How to fix?

Upgrade Debian:10 bash to version 4.4-1 or higher.

NVD Description

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

Bash before 4.4 allows local users to execute arbitrary commands with root privileges via crafted SHELLOPTS and PS4 environment variables.
