The DataDirect ODBC Drivers used by IBM App Connect and IBM Integration Bus have addressed the applicable CVEs. Vulnerability Details CVEID: CVE-2018-0732 DESCRIPTION: During key agreement in a TLS handshake using a DH(E) based ciphersuite a malicious server can send a very large prime value to the client. This will cause the client to spend an unreasonably long period of time generating a key for this prime resulting in a hang until the client has finished. This could be exploited in a Denial Of Service attack. Fixed in OpenSSL 1.1.0i-dev (Affected 1.1.0-1.1.0h). Fixed in OpenSSL 1.0.2p-dev (Affected 1.0.2-1.0.2o).
