Descriptions
The signature of a digitally signed S/MIME email message may optionally specify the signature creation date and time. If present, Thunderbird did not compare the signature creation date with the message date and time, and displayed a valid signature despite a date or time mismatch. This could be used to give recipients the impression that a message was sent at a different date or time. This vulnerability affects Thunderbird < 115.6.
La firma de un mensaje de correo electrónico S/MIME firmado digitalmente puede especificar opcionalmente la fecha y hora de creación de la firma. Si estaba presente, Thunderbird no comparó la fecha de creación de la firma con la fecha y hora del mensaje y mostró una firma válida a pesar de que la fecha y la hora no coincidían. Esto podría usarse para dar a los destinatarios la impresión de que un mensaje se envió en una fecha u hora diferente. Esta vulnerabilidad afecta a Thunderbird < 115.6.
