Subject: [PATCH] SNI: added restriction for TLSv1.3 cross-SNI session
|
||||
resumption.
|
||||
|
||||
In OpenSSL, session resumption always happens in the default SSL context,
|
||||
prior to invoking the SNI callback. Further, unlike in TLSv1.2 and older
|
||||
protocols, SSL_get_servername() returns values received in the resumption
|
||||
handshake, which may be different from the value in the initial handshake.
|
||||
Notably, this makes the restriction added in b720f650b insufficient for
|
||||
sessions resumed with different SNI server name.
|
||||
|
||||
Considering the example from b720f650b, previously, a client was able to
|
||||
request example.org by presenting a certificate for example.org, then to
|
||||
resume and request example.com.
|
||||
|
||||
The fix is to reject handshakes resumed with a different server name, if
|
||||
verification of client certificates is enabled in a corresponding server
|
||||
configuration.

||||

||||
