How to fix?

Upgrade Echo:latest opendkim to version 2.11.0~beta2-8+deb12u1 or higher.

NVD Description

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

An issue was discovered in OpenDKIM through 2.10.3, and 2.11.x through 2.11.0-Beta2. It fails to keep track of ordinal numbers when removing fake Authentication-Results header fields, which allows a remote attacker to craft an e-mail message with a fake sender address such that programs that rely on Authentication-Results from OpenDKIM will treat the message as having a valid DKIM signature when in fact it has none.
