The key thing to do is to make those client applications not request the
ssl23-method from OpenSSL 0.9.x .
ssl23 explicitly requests this backward-compatibility feature while
OpenSSL 3.x.x apparently deleted the
ability to respond to this "historic" TLS hello format, which is also
sent by some not-that-old web browsers.

Patrick,
I am also supporting servers running very old Linux systems and I can
tell you that YES you can upgrade from source. I have built
openssl-1.1.1 from source on such systems with no problems.

Hello,
I'm using an old version of OpenSSL (0.9.8g) on an old Linux Debian
distribution (Lenny).
Is it possible to upgrade OpenSSL version without upgrading Linux
Debian
distribution ?
If yes, up to which version of OpenSSL ?
Are all versions of OpenSSL compliant with all Linux Debian
distribution ?
Thank you in advance for your answer.
Best Regards,
Enjoy
Jakob
