Description
CVE-2020-28896: https://nvd.nist.gov/vuln/detail/CVE-2020-28896
Mutt before 2.0.2 and NeoMutt before 2020-11-20 did not ensure that
$ssl_force_tls was processed if an IMAP server's initial server
response was invalid. The connection was not properly closed, and the
code could continue attempting to authenticate. This could result in
authentication credentials being exposed on an unencrypted connection,
or to a machine-in-the-middle.
Fixed in >= 2.0.2
