If Thunderbird was configured to use STARTTLS for an IMAP connection, and
an attacker injected IMAP server responses prior to the completion of the
STARTTLS handshake, then Thunderbird didn’t ignore the injected data. This
could have resulted in Thunderbird showing incorrect information, for
example the attacker could have tricked Thunderbird to show folders that
didn’t exist on the IMAP server. This vulnerability affects Thunderbird <
78.12.
