Subject: [PATCH] Issue 51129 - SSL alert: The value of sslVersionMax "TLS1.3"
is higher than the supported version
Bug Description: If you try and set the sslVersionMax higher than the
default range, but within the supported range, you
would still get an error and the server would reset
the max to "default" max value.
Fix Description: Keep track of both the supported and default SSL ranges,
and correctly use each range for value validation. If
the value is outside the supported range, then use default
value, etc, but do not check the requested range against
the default range. We only use the default range if
there is no specified min or max in the config, or if
a invalid min or max value is set in the config.
Also, refactored the range variable names to be more
accurate:
enabledNSSVersions --> defaultNSSVersions
emin, emax --> dmin, dmax
