Notes:

• The Solaris 32bit (x86 and sparc) Java fix for CVE-2020-2654 is available from IBM as Java 7.0.10.65 but is not yet packaged for installation by the ClearQuest Installation Manager. Therefore, Solaris 32bit is still vulnerable to this CVE.

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 April 2020 CPU plus deferred CVE-2019-2949 and CVE-2020-2654
   and apply the latest available fix for the version of WAS used for CM server.
