Notes: - If you use CCRC as an extension offering installed into an Eclipse shell (one not provided as part of a ClearCase release), or you use rcleartool or CMAPI using a Java(TM) Virtual Machine not supplied by IBM as part of Rational ClearCase, you should update the Java(TM) Virtual Machine that you use to include a fix for the above issues. Contact the supplier of your Java(TM) Virtual Machine and/or the supplier of your Eclipse shell. - There is no Java(TM) Virtual Machine fix for HP-UX available in ClearCase 8.0.1.19. Please see https://developer.ibm.com/javasdk/support/ lifecycle/ for more details. CCRC WAN server fixes +-------------------+---------------------------------------------------------+ | Affected Versions | Applying the fix | +-------------------+---------------------------------------------------------+ |9.0.0.x |Apply the appropriate WebSphere Application Server fix | |9.0.1.x |directly to your CCRC WAN server host. No | |8.0.1.x |ClearCase-specific steps are necessary. | |8.0.0.x | | +-------------------+---------------------------------------------------------+ o 1. Determine the WAS version used by your CCRC WAN server. Navigate to the CCRC profile directory (either the profile you specified when installing ClearCase, or <ccase-home>/common/ccrcprofile), then execute the script: bin/versionInfo.sh (UNIX) or bin\versionInfo.bat (Windows). The output includes a section "IBM WebSphere Application Server". Make note of the version listed in this section. 2. Review the following WAS security bulletin: Security Bulletin: Multiple vulnerabilities in IBM(R) Java SDK affects WebSphere Application Server July 2018 CPU and apply the latest available fix for the version of WAS used for CCRC WAN server. - Note: there may be newer security fixes for WebSphere Application Server.

You use the base ClearCase/ClearQuest integration client on any platform, configured to use SSL to communicate with a ClearQuest server. 2. You use the UCM/ClearQuest integration on UNIX/Linux clients, configured to use SSL to communicate with a ClearQuest server. Note: Windows clients using the UCM/ClearQuest integration are not vulnerable. 3. On UNIX/Linux clients, you use the Change Management Integration (CMI), when configured to use SSL to communicate with the server.
