Description Sam James archtester gentoo-dev Security 2020-06-19 19:57:27 UTC
"Alpine can be configured to start a secure connection using /tls on
an insecure connection. However, if the connection is PREAUTH,
Alpine will not upgrade the connection to a secure connection,
because a client must not issue a STARTTLS to a server that supports
it, while in authenticated state. 

This makes Alpine continue to use
an insecure connection with the server, exposing user data. Reported
by Damian Poddebniak and Fabian Ising from Münster University of
Applied Sciences. "

Yes. Do we need a separate bug for this?
