Description Mauro Matteo Cascella 2023-07-17 12:51:31 UTC

An issue was discovered in OpenDKIM through 2.10.3, and 2.11.x through 2.11.0-Beta2. OpenDKIM 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.
