After updating the Oracle Managed Client from version 21.8 to 21.9 we cannot connect to the DB anymore. The stack trace mentions a SSL handshake failure.
We are using .Net 4.7.2 at a windows 2019 VM. The database version is 19c.
For the connection a client wallet with a client certificate and the db certificate inside is used. We have also installed the db certificate inside the trusted people store at the windows VM.
When I look at the change log for the version 21.9 it seems the fix for cve-2023-21893 has something to do with the SSL connection. Can it be that there has something be changed that is now causing the issue?
