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.
