Descriptions

K-9 Mail v5.600 can include the original quoted HTML code of a specially crafted, benign looking, email within (digitally signed) reply messages. The quoted part can contain conditional statements that show completely different text if opened in a different email client. This can be abused by an attacker to obtain valid S/MIME or PGP signatures for arbitrary content to be displayed to a third party. NOTE: the vendor states "We don't plan to take any action because of this."

K-9 Mail v5.600 puede incluir el código HTML original entrecomillado de un correo electrónico especialmente manipulado y de aspecto benigno en los mensajes de respuesta (con firma digital). La parte entrecomillada puede contener instrucciones condicionales que muestran un texto completamente distinto si se abre en un cliente de correo electrónico diferente. Un atacante podría aprovechar esto para obtener firmas S/MIME o PGP válidas para que se muestre contenido arbitrario a un tercero. NOTA: el proveedor afirma "No tenemos la intención de emprender ninguna acción por esto".
