IBM Rational ClearQuest has addressed the applicable CVEs. Vulnerability Details If you run your own Java code using the IBM Java Runtime delivered with this product, you should evaluate your code to determine whether additional Java vulnerabilities are applicable to your code. For a complete list of vulnerabilities, refer to the "IBM Java SDK Security Bulletin", located in the References section for more information. CVEID: CVE-2019-4473 DESCRIPTION: Multiple binaries in IBM SDK, Java Technology Edition on the AIX platform use insecure absolute RPATHs, which may facilitate code injection and privilege elevation by local users. CVSS Base Score: 8.4 CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/ 163984 for the current score CVSS Environmental Score*: Undefined CVSS Vector: (CVSS:3.0/AV:L/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H) CVEID: CVE-2019-11771 DESCRIPTION: Eclipse OpenJ9 could allow a local attacker to gain elevated privileges on the system, caused by the inclusion of unused RPATHS in AIX builds. An attacker could exploit this vulnerability to inject code and gain elevated privileges on the system. CVSS Base Score: 8.4 CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/ 163989 for the current score CVSS Environmental Score*: Undefined CVSS Vector: (CVSS:3.0/AV:L/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H) Affected Products and Versions IBM Rational ClearQuest version 9 on AIX 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 | +---------------------------------------+-------------------------------------+ | 9.0.1 through 9.0.1.8 | Affected | +---------------------------------------+-------------------------------------+ | 9.0 through 9.0.0.6 | Affected | +---------------------------------------+-------------------------------------+ Remediation/Fixes The solution is to install a fix that includes an updated Java(TM) 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 | +------------------------+-------------------------------------------------------------------------+ | 9.0.1 through 9.0.1.8 |Contact support to get the fixes from the test fix portal | | 9.0 through 9.0.0.6 | | +------------------------+-------------------------------------------------------------------------+ 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(R) Java SDK affect WebSphere Application Server July 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.
