Security Bulletin
Summary
There are multiple vulnerabilities in IBM® SDK Java™ Technology Edition that is shipped with IBM Rational Synergy. These issues were disclosed as part of the IBM Java SDK updates in January 2015. This bulletin also addresses the “FREAK: Factoring Attack on RSA-EXPORT keys" TLS/SSL client and server vulnerability.
Vulnerability Details
CVEID: CVE-2015-0138
DESCRIPTION: A vulnerability in various IBM SSL/TLS implementations could allow a remote attacker to downgrade the security of certain SSL/TLS connections. An IBM SSL/TLS client implementation could accept the use of an RSA temporary key in a non-export RSA key exchange ciphersuite. This could 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.

Remediation/Fixes
Replace the JRE used in Rational Synergy.
Steps to download and replace JRE in Rational Synergy:
1. Open the list of Synergy downloads on Fix Central
2. Select the SDK and Readme for Rational Synergy which applied to your release as follows:
Note: The fix will use the following naming convention:
<V.R.M.F>-Rational-RATISYNE-JavaSE-SDK-6.0.16.3-<platform>
Where <V.R.M.F> = release & <platform> = operating system
o Rational Synergy 7.2.1 (uses 7.2.1.3 release designation)
Example: 7.2.1.3-Rational-RATISYNE-JavaSE-SDK-6.0.16.3-Linux
o Rational Synergy 7.2.0 (uses 7.2.0.7 release designation)
Example: 7.2.0.7-Rational-RATISYNE-JavaSE-SDK-6.0.16.3-Windows
o Rational Synergy 7.1 (uses 7.1.0.7 release designation)
Example: 7.1.0.7-Rational-RATISYNE-JavaSE-SDK-6.0.16.3-AIX
Example: 7.1.0.7-Rational-RATISYNE-JavaSE-SDK-6.0.16.3-Solaris
3. Follow the steps in the Install instructions to replace the JRE.
