How to fix?

Upgrade Debian:10 exim4 to version 4.92-8+deb10u1 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream exim4 package and not the exim4 package as distributed by Debian. See How to fix? for Debian:10 relevant fixed versions and status.

Exim 4.85 through 4.92 (fixed in 4.92.1) allows remote code execution as root in some unusual configurations that use the ${sort } expansion for items that can be controlled by an attacker (e.g., $local_part or $domain).
