TIBCO Enterprise Message Service, TIBCO FTL/eFTL, and TIBCO Rendezvous will require strengthening ciphers and certificates, and removing older, exploitable protocols, as a result of supporting OpenSSL 3.0.

The following TIBCO BusinessWorks versions have been tested with Rendezvous 8.6.0 / Enterprise Message Service 10.2 and have the required minimum version of JRE which support OpenSSL 3.0 :

• BusinessWorks 5.15.0 (TRA 5.12.2 / 5.12.1) 
• BusinessWorks 5.14.1 (TRA 5.11.3)
• BusinessWorks 6.9.0, 6.8.1 hotfix-03 and 6.8.0 hotfix-03 

Customers on BW 6.7.0 should apply hotfix-08 and have Java 1.8.0_351 (or above). If you need to apply the latest JRE patch then contact TIBCO Support.

For more details on the complete impact of OpenSSL 3.0 on TIBCO Enterprise Message Service, TIBCO FTL/eFTL, and TIBCO Rendezvous refer the below article:
