How to fix?

Upgrade Debian:12 exim4 to version 4.82.1-1 or higher.

NVD Description

Note: Versions mentioned in the description apply to the upstream exim4 package. See How to fix? for Debian:12 relevant versions.

The dmarc_process function in dmarc.c in Exim before 4.82.1, when EXPERIMENTAL_DMARC is enabled, allows remote attackers to execute arbitrary code via the From header in an email, which is passed to the expand_string function.
