CVEID: CVE-2016-2183**
DESCRIPTION:** OpenSSL could allow a remote attacker to obtain sensitive information, caused by an error in the DES/3DES cipher, used as a part of the SSL/TLS protocol. By capturing large amounts of encrypted traffic between the SSL/TLS server and the client, a remote attacker able to conduct a man-in-the-middle attack could exploit this vulnerability to recover the plaintext data and obtain sensitive information. This vulnerability is known as the SWEET32 Birthday attack.

Remediation/Fixes

IMPORTANT CONSIDERATIONS:

1. If your product is deployed on WebSphere Application Server (WAS) and your deployment does not use an Eclipse based client nor the RM Browser plugin, then it is sufficient to continue using the existing version of your IBM Rational product, and only upgrade the JRE in the WAS server.
2. For the below remediations, if you are a WAS deployment, then WAS must also be remediated, in addition to performing your product upgrades. Follow instructions at Security Bulletin: Multiple vulnerabilities in IBM® Java SDK affects WebSphere Application Server January 2017 CPU to get the WAS remediation .
3. If you are deploying the Rational products to a WAS Liberty or a Tomcat Server, you will need to follow the instructions below to upgrade the JRE, and then must also configure to complete the upgrade process:
   3.1. Stop the server: Navigate to the Server directory in your Ratonal product installation path and run this script: server.shutdown

3.2. Navigate to the server directory in your Rational product installation path, open server.startup_ _script using prefered text editor (e.g., Notepad for Windows or Vim Editor for Linux) and add one more option to the healthcenter parameter set:
Search parameter -Dcom.ibm.java.diagnostics.healthcenter.agent in server.startup script to find the line containing the health center parameter.

NOTE: For some Rational Collaborative Lifecycle Management versions,_ -Dcom.ibm.java.diagnostics.healthcenter.agent_ parameter may not be found in the server.startup, in this case the update is not needed and you can start using your server.
**
Windows:**
Modify the line (where HEALTHCENTER_OPTS parameter located) by adding a new healthcenter option: _
_-Dsun.rmi.registry.registryFilter=javax.rmi.CORBA.Stub

Before modification:_
set HEALTHCENTER_OPTS=-agentlib:healthcenter -Dcom.ibm.java.diagnostics.healthcenter.agent.port=1972
After modification:
set HEALTHCENTER_OPTS=-agentlib:healthcenter -Dcom.ibm.java.diagnostics.healthcenter.agent.port=1972 _-Dsun.rmi.registry.registryFilter=javax.rmi.CORBA.Stub
**
Linux:**
Modify the line (where HEALTHCENTER_OPTS parameter located) by adding a new healthcenter option: -Dsun.rmi.registry.registryFilter=javax.rmi.CORBA.Stub

Before modification:_
export HEALTHCENTER_OPTS=“-agentlib:healthcenter -Dcom.ibm.java.diagnostics.healthcenter.agent.port=1972”
After modification:
export HEALTHCENTER_OPTS=“-agentlib:healthcenter -Dcom.ibm.java.diagnostics.healthcenter.agent.port=1972 -Dsun.rmi.registry.registryFilter=javax.rmi.CORBA.Stub”_
3.3. Start the server. Navigate to the Server directory in your Rational product installation path and run this script: server.startup_. _ STEPS TO APPLY THE REMEDIATION:
_ _
1. Upgrade your products to a supported version:4.0.7,5.0.2,6.0.2, or 6.0.3
2. Apply the latest ifix for your installed version.
3. Obtain the January 2017 CPU update for the IBM_®_ Java SDK.
