Security Bulletin: Multiple vulnerabilities in IBM Java SDK affect IBM SPSS Modeler (CVE-2015-4000, CVE-2015-0478, CVE-2015-0488)

Summary

There are multiple vulnerabilities in IBM SDK Java Technology Edition, Version 6 Service Refresh 16 Fix Pack 3, IBM SDK Java Technology Edition, Version 7 Service Refresh 8 Fix Pack 10, and IBM SDK Java Technology Edition, Version 7R1 Service Refresh 2 Fix Pack 10 that are used by IBM SPSS Modeler. These issues were disclosed as part of the IBM Java SDK updates in April 2015 and IBM Java SDK update addressing TLS protocol vulnerability involving DHE_EXPORT ciphersuite.

Vulnerability Details

CVEID: CVE-2015-4000**
DESCRIPTION:** The TLS protocol could allow a remote attacker to obtain sensitive information, caused by the failure to properly convey a DHE_EXPORT ciphersuite choice. An attacker could exploit this vulnerability using man-in-the-middle techniques to force a downgrade to 512-bit export-grade cipher. Successful exploitation could allow an attacker to recover the session key as well as modify the contents of the traffic. This vulnerability is commonly referred to as “Logjam”.

You should verify applying this configuration change does not cause any compatibility issues. If you change the default setting after applying the fix, you will expose yourself to the attack described above. IBM recommends that you review your entire environment to identify other areas where you have enabled the Diffie-Hellman key-exchange protocol used in TLS and take appropriate mitigation and remediation actions.
