I wonder… perhaps the use of SNI, both in the TLSv1.3 standard
and in some TLSv1.2 implementations, should receive CVEs as well?
It certainly ought to be disabled by default. Perhaps add some
environment variable to enable SNI in the SSL library, and if
it’s not present or explicitly set to 0, disable SNI (which also
would disable TLSv1.3 as it requires SNI). Hmm, yes, this sounds
completely like a good idea.
(Considering SNI also leaks the vhost addressed by the end user,
which is otherwise hidden with wildcard certificates or grouped
with tone others in multi-subjectAltName certificates, it ought
to have been anyway.)
