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.
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.

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.
Follow the steps in the HPUX_Install Instructions to replace the JRE if your Synergy Platform is on HPUX.
