How to fix?

Upgrade Debian:10 bash to version 4.3-9.2 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.

The redirection implementation in parse.y in GNU Bash through 4.3 bash43-026 allows remote attackers to cause a denial of service (out-of-bounds array access and application crash) or possibly have unspecified other impact via crafted use of here documents, aka the "redir_stack" issue.
