Affected Products and Versions

Affected Product(s) Version(s)
IBM Rational ClearCase 8.0.0
IBM Rational ClearCase 9.0
IBM Rational ClearCase 9.0.1
IBM Rational ClearCase 9.1
IBM Rational ClearCase 9.0.2
IBM Rational ClearCase 8.0.1

Remediation/Fixes

The solution is to install a fix that includes an updated Java™ Virtual Machine with fixes for the issues, and to apply fixes for WebSphere Application Server (WAS).

Client and server fixes

Apply the relevant fixes as listed in the table below.

Affected Versions

|

Applying the fix

—|—
9.1 through 9.1.0.3| Install Rational ClearCase Fix Pack 3 (9.1.0.3) for 9.1

9.0.2 through 9.0.2.6

| Install Rational ClearCase Fix Pack 6 (9.0.2.6) for 9.0.2

9.0.1 through 9.0.1.14
9.0 through 9.0.0.6

| Install Rational ClearCase Fix Pack 14 (9.0.1.14) for 9.0.1

For 8.0 and earlier releases, IBM recommends upgrading to a fixed, supported version/release/platform of the product.

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™ Virtual Machine not supplied by IBM as part of Rational ClearCase, you should update the Java™ Virtual Machine that you use to include a fix for the above issues. Contact the supplier of your Java™ Virtual Machine and/or the supplier of your Eclipse shell.

CCRC WAN server fixes

Affected Versions

Applying the fix

—|—

9.0.0.x
9.0.1.x
9.0.2.x
9.1.0.x

| Apply the appropriate WebSphere Application Server fix directly to your CCRC WAN server host. No ClearCase-specific steps are necessary.

  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® Java SDK affect IBM WebSphere Application Server and IBM WebSphere Application Server Liberty due to April 2022 CPU plus deferred CVE-2022-21299
    Security Bulletin: Multiple Vulnerabilities in IBM® Java SDK affect IBM WebSphere Application Server and IBM Application Server Liberty due to January 2022 CPU plus deferred CVE-2021-35550 and CVE-2021-35603
    Security Bulletin: Multiple Vulnerabilities in IBM® Java SDK affect WebSphere Application Server October 2021 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. Subscribe to “My Notifications” to be notified about WebSphere product support alerts for additional Java SDK fixes.
