Security Bulletin
Summary
The "FREAK: Factoring Attack on RSA-EXPORT keys" TLS/SSL client and server
vulnerability affects IBM SDK Java Technology Edition, Version 6 that is
used by IBM Decision Optimization Center.
Vulnerability Details
CVEID: CVE-2015-0138
DESCRIPTION: A vulnerability in various IBM SSL/TLS implementations might
allow a remote attacker to downgrade the security of certain SSL/TLS
connections. An IBM SSL/TLS client implementation can accept the use of an
RSA temporary key in a non-export RSA key exchange cipher suite. This might
allow a remote attacker using man-in-the-middle techniques to facilitate
brute-force decryption of TLS/SSL traffic between vulnerable clients
and servers.
This vulnerability is also known as the FREAK attack.
CVSS Base Score: 4.3
CVSS Temporal Score: See

Affected Products and Versions
IBM Decision Optimization Center: v3.8 and earlier
Remediation/Fixes
The recommended solution is to download and install IBM Java SDK version
6 Service Refresh 16 Fix Pack 3 with fixes for CVE-2015-0138 (FREAK)
as soon as practicable.
Before installing a newer version of IBM Java SDK, ensure that you:
Close any open programs that you have running;
Rename the initial directory of the IBM Java SDK (for example:
