summary
Buffer Copy without Checking Size of Input ('Classic Buffer Overflow')
The olm_session_describe function in Matrix libolm is vulnerable to a buffer overflow. The Olm session object represents a cryptographic channel between two parties. Therefore, its state is partially controllable by the remote party of the channel. Attackers can construct a crafted sequence of messages to manipulate the state of the receiver's session in such a way that, for some buffer sizes, a buffer overflow happens on a call to olm_session_describe. Furthermore, safe buffer sizes were undocumented. The overflow content is partially controllable by the attacker and limited to ASCII spaces and digits. The known affected products are Element Web And SchildiChat Web.

summary
When receiving an OpenPGP/MIME signed email message that contains an
additional outer MIME message layer, for example a message footer added by a
mailing list gateway, Thunderbird only considered the inner signed message for
the signature validity. This gave the false impression that the additional contents
were also covered by the digital signature. Starting with Thunderbird version 91.4.1,
only the signature that belongs to the top level MIME part will be considered for
the displayed status.

summary Thunderbird ignored the configuration to require STARTTLS security for an SMTP connection. A MITM could perform a downgrade attack to intercept transmitted messages, or could take control of the authenticated session to execute SMTP commands chosen by the MITM. If an unprotected authentication method was configured, the MITM could obtain the authentication credentials, too.
