that gnupg now flags message streams which contain multiple plaintexts
as an error. This prevents errors which would occur when applications
which called gnupg assumed that this was already the default behavior.

Note that Tenable Network Security has extracted the preceding
description block directly from the Fedora security advisory. Tenable
has attempted to automatically clean and format it as much as possible
without introducing additional issues."

GnuPG is a utility for encrypting data and creating digital

use of GnuPG are prone to a vulnerability involving incorrect

arbitrary content to a signed message in such a way that a receiver of
the message would not be able to distinguish between the properly
signed parts of a message and the forged, unsigned, parts.
