|
|
|
-
|
|
|
-* \[High\] A TLS v1.3 server who requires mutual authentication can be
|
|
|
- bypassed. If a malicious client does not send the certificate_verify
|
|
|
- message a client can connect without presenting a certificate even
|
|
|
- if the server requires one. Thank you to Aina Toky Rasoamanana and
|
|
|
- Olivier Levillain of Télécom SudParis.
|
|
|
-* \[High\] A TLS v1.3 client attempting to authenticate a TLS v1.3
|
|
|
- server can have its certificate check bypassed. If the sig_algo in
|
|
|
- the certificate_verify message is different than the certificate
|
|
|
- message checking may be bypassed. Thank you to Aina Toky Rasoamanana and
|
|
