Description Pedro Sampaio 2020-04-27 17:17:50 UTC

Two vulnerabilities in openDMARC 1.3.2:

OpenDMARC through 1.3.2 and 1.4.x allows attacks that inject authentication results to provide false information about the domain that originated an e-mail message. This is caused by incorrect parsing and interpretation of SPF/DKIM authentication results, as demonstrated by the example.net(.example.com substring.

OpenDMARC through 1.3.2 and 1.4.x, when used with pypolicyd-spf 2.0.2, allows attacks that bypass SPF and DMARC authentication in situations where the HELO field is inconsistent with the MAIL FROM field.
