How to fix?

Upgrade Debian:12 exim4 to version 4.76-1 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 DKIM implementation in Exim 4.7x before 4.76 permits matching for DKIM identities to apply to lookup items, instead of only strings, which allows remote attackers to execute arbitrary code or access a filesystem via a crafted identity.
