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.

with fixes for the issues, and to apply fixes for WebSphere Application Server
(WAS).

+--------------------------------------------------------------------------------------+

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/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
    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                     |
|-------------------+---------------------------------------------------------|
|9.0.0.x            |Apply the appropriate WebSphere Application Server fix   |
|9.0.1.x            |directly to your CM server host. No ClearQuest-specific  |
|                   |steps are necessary.                                     |
+-----------------------------------------------------------------------------+
