Notes:CCRC WAN server fixes
|
Affected Versions
|
Applying the fix
|
|
9.0.0.x | Apply the appropriate WebSphere Application Server fix directly to your CCRC WAN server host. No ClearCase-specific steps are necessary. |
- 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:
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.
