Severity ?
Summary
An issue was discovered in Enigmail before 1.9.9. Signature spoofing is possible because the UI does not properly distinguish between an attachment signature, and a signature that applies to the entire containing message, aka TBE-01-021. This is demonstrated by an e-mail message with an attachment that is a signed e-mail message in message/rfc822 format.

Se puede dar una suplantaci\u00f3n de firma debido a que la interfaz de usuario no distingue correctamente entre una firma adjunta y una firma que aplica a todo el mensaje. Esto tambi\u00e9n se conoce como TBE-01-021. Esto se demuestra con un mensaje de correo electr\u00f3nico con un adjunto que es un mensaje de correo firmado en formato message/rfc822."
