Public bug reported: Currently freetds is built against gnutls library, but has support for both gnutls & openssl.
It tries to set priority strings, and sets them to lower values that are default in Ubuntu and/or supported by SQL Server. Please stop directly setting gnutls priority string, or use the same one as is used in gnutls in Ubuntu. NORMAL:-VERS-ALL:+VERS-TLS1.3:+VERS- TLS1.2:+VERS-DTLS1.2:%PROFILE_MEDIUM Alternatively, please build using openssl library, as that would ensure that security level 2 is enforced without any code changes of freetds. (Built in default is DEFAULT@SECLEVEL=2) All recent/updated version of SQL Server support TLSv1.2 https://support.microsoft.com/en-gb/help/3135244/tls-1-2-support-for- microsoft-sql-server ** Affects: freetds (Ubuntu) Importance: Undecided Status: New -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1891805 Title: Uses lower than default TLS settings To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/freetds/+bug/1891805/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
