CVSS: 6.5EPSS: 0%CPEs: 1EXPL: 0CVE-2021-4126
https://notcve.org/view.php?id=CVE-2021-4126
When receiving an OpenPGP/MIME signed email message that contains an additional outer MIME message layer, for example a message footer added by a mailing list gateway, Thunderbird only considered the inner signed message for the signature validity. This gave the false impression that the additional contents were also covered by the digital signature. Starting with Thunderbird version 91.4.1, only the signature that belongs to the top level MIME part will be considered for the displayed status. This vulnerability affects Thunderbird < 91.4.1. Al recibir un mensaje de correo electrónico firmado con OpenPGP/MIME que contiene una capa de mensaje MIME externa adicional, por ejemplo un pie de página de mensaje agregado por una puerta de enlace de lista de correo, Thunderbird solo consideró el mensaje firmado interno para la validez de la firma. • https://bugzilla.mozilla.org/show_bug.cgi?id=1732310 https://www.mozilla.org/security/advisories/mfsa2021-55 •
