Affected Products and Versions
IBM Rational ClearCase, versions 7.1.0.x, 7.1.1.x, 7.1.2.x, 8.0.0.x, 8.0.1.x, in the following components:
- CCRC WAN server/CM Server component, when configured to use SSL
- ClearCase remote client: CCRC/CTE GUI, rcleartool, and CMAPI clients, when using SSL to access a CCRC WAN Server/CM Server
ClearCase version | Status |
8.0.1 through 8.0.1.8 | Affected |
8.0 through 8.0.0.15 | Affected |
7.1.0.x 7.1.1.x 7.1.2.x (all versions and fix packs) | Affected |
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).
CCRC Client fixes
- Apply the relevant fix pack as listed in the table below.
- 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 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.
Affected Versions | Fix pack |
8.0.1 through 8.0.1.7 | Install Rational ClearCase Fix Pack 8 (8.0.1.10) |
8.0 through 8.0.0.14 | Install Rational ClearCase Fix Pack 15 (8.0.0.17) |
7.1.2.x (all fix packs) 7.1.1.x (all fix packs) 7.1.0.x (all fix packs) | Customers on extended support contracts should contact customer support. |
Notes:
- 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.
- Review the following WAS security bulletin:
and apply the fixes for the version of WAS used for CCRC WAN server.
Affected Versions | Applying the fix |
| 8.0.0.x 8.0.1.x | Apply the appropriate WebSphere Application Server fix directly to your CCRC WAN server host. No ClearCase-specific steps are necessary. |
| 7.1.2.x (all fix packs) 7.1.1.x (all fix packs) 7.1.0.x (all fix packs) | Customers on extended support contracts should contact customer support. |
