Affected Products and Versions

IBM Rational ClearQuest version 9 in the following components:

  • ClearQuest Web/CQ OSLC server/CM Server component, when configured to use SSL.
  • ClearQuest Eclipse clients that use Report Designer, run remote reports on servers using secure connections, or use the embedded browser to connect to secure web sites. If you do not use the ClearQuest Eclipse client in this way, then you are not affected.
ClearQuest version
Status on linux_x86 (32-bit) Affected
9.0.1 through
9.0 through


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).

ClearQuest Eclipse Clients
Apply the relevant fixes as listed in the table below.

Affected Versions
Applying the fix on linux_x86 (32-bit) Install Rational ClearQuest Fix Pack 8 ( for 9.0.1
9.0.1 through
9.0 through
Install Rational ClearQuest Fix Pack 7 ( or higher for 9.0.1

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

ClearQuest Web/CQ OSLC Server/CM Server Component

  1. Determine the WAS version used by your CM server. Navigate to the CM profile directory (either the profile you specified when installing ClearQuest, or <clearquest-home>/cqweb/cqwebprofile), then execute the script: bin/ (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 WebSphere Application Server January 2019 CPU
    and apply the latest available fix for the version of WAS used for CM server.

Note: there may be newer security fixes for WebSphere Application Server. Follow the link above (in the section "Get Notified about Future Security Bulletins") to subscribe to WebSphere product support alerts for additional Java SDK fixes.

Affected Versions
Applying the fix


Apply the appropriate WebSphere Application Server fix directly to your CM server host. No ClearQuest-specific steps are necessary.
