USN-432-1: GnuPG vulnerability

Publication date

Overview

GnuPG vulnerability

Releases

Details

Gerardo Richarte from Core Security Technologies discovered that when
gnupg is used without --status-fd, there is no way to distinguish
initial unsigned messages from a following signed message. An attacker
could inject an unsigned message, which could fool the user into
thinking the message was entirely signed by the original sender.
