For the below remediations, if you have 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 October 2017 CPU to get the WAS remediation . 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: Comment out the line (where HEALTHCENTER_OPTS parameter located) by inserting "rem " at the beginning of the line: Before modification: set HEALTHCENTER_OPTS=-agentlib:healthcenter ... After modification: rem set HEALTHCENTER_OPTS=-agentlib:healthcenter ... Linux: Comment out the line (where HEALTHCENTER_OPTS parameter located) by inserting "# " at the beginning of the line: Before modification: export HEALTHCENTER_OPTS="-agentlib:healthcenter ... After modification: # export HEALTHCENTER_OPTS="-agentlib:healthcenter ... 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: 5.0.2, 6.0.2, or 6.0.5 2. Apply the latest ifix for your installed version. 3. Obtain the October 2017 CPU update for the IBM Java SDK. Based on version installed, obtain the latest ifixes (recommended), and the below indicated java from: For the 6.0.2 and 6.0.5 releases: JRE 7.1.4.15 (<product>-JavaSE-JRE-7.1SR4FP15) Rational Collaborative Lifecycle Management 6.0.2 For the 5.x releases: guidance will be published in the future. 4. Upgrade your JRE following the instructions in the link below: How to update the IBM SDK for Java of IBM Rational products based on version 3.0.1.6 or later of IBM's Jazz technology 5. Navigate to the server directory in your Rational product installation path, and go to jre/lib/security path. 6. Open java.security file using prefered text editor (e.g., Notepad for Windows or Vim Editor for Linux) and remove MD5 option from the jdk.jar.disabledAlgorithms parameter set: Before modification: jdk.jar.disabledAlgorithms=MD2, MD5, RSA keySize < 1024 After modification: jdk.jar.disabledAlgorithms=MD2, RSA keySize < 1024 Workarounds and Mitigations None Get Notified about Future Security Bulletins Subscribe to My Notifications to be notified of important product support alerts like this. Important note IBM strongly suggests that all System z customers be subscribed to the System z Security Portal to receive the latest critical System z security and integrity service. If you are not subscribed, see the instructions on the System z Security web site. Security and integrity APARs and associated fixes will be posted to this portal. IBM suggests reviewing the CVSS scores and applying all security or integrity fixes as soon as possible to minimize any potential risk.
