Security Bulletin


Summary

There are multiple vulnerabilities in IBM(R) Runtime Environment Java(TM) Versions 7
and 8, which are used by IBM Rational ClearQuest on the AIX platform. 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.
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.                                     |
