FYI ...

IBM Informix Dynamic Server can be affected by a TLS (Transport Layer Security) padding vulnerability which can allow a remote attacker to obtain sensitive information.

Workarounds and Mitigations:

In the IBM Informix Dynamic Server environment, set GSK_STRICTCHECK_CBCPADBYTES=GSK_TRUE
Restart the oninit process in order for the environment setting to take affect.
