Descriptions

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 versiones hasta 1.3.2 y versiones 1.4.x, permite ataques que inyectan resultados de autenticación para proporcionar información falsa acerca del dominio que originó un mensaje de correo electrónico. Esto es causado por el análisis e interpretación incorrecta de los resultados de la autenticación SPF/DKIM, como es demostrado por la subcadena example.net(.example.com
