CVE-2021-22946 Crafted answers from a server might force clients to not use TLS on connections though TLS was required and expected. CVE-2021-22947 When using STARTTLS to initiate a TLS connection, the server might send multiple answers before the TLS upgrade and such the client would handle them as being trusted. This could be used by a MITM-attacker to inject fake response data.
