Mutt 1.5.13 and earlier does not properly use the –status-fd argument when invoking GnuPG, which prevents Mutt from visually distinguishing between signed and unsigned portions of OpenPGP messages with multiple components, which allows remote attackers to forge the contents of a message without detection.
