Security Bulletin


Summary

There are multiple vulnerabilities in IBM(R) Runtime Environment Java(TM) Versions 7
and 8 used by IBM Rational ClearCase on the AIX platform. IBM Rational
ClearCase 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 ClearCase version 9 on AIX in the following components:

  - CCRC WAN server/CM Server component, when configured to use SSL
  - ClearCase remote client: CCRC/CTE GUI, rcleartool, and CMAPI clients

+---------------------------------------+-------------------------------------+
|           ClearCase 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).

Client and server fixes

Apply the relevant fixes as listed in the table below.
+-------------------+---------------------------------------------------------+
| Affected Versions |                    Applying the fix                     |
+-------------------+---------------------------------------------------------+
|   9.0.1 through   |Contact support to get the fixes from the test fix portal|
|      9.0.1.8      |                                                         |
|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.

Note:

  o If you use CCRC as an extension offering installed into an Eclipse shell
    (one not provided as part of a ClearCase release), or you use rcleartool or
    CMAPI using a Java(TM) Virtual Machine not supplied by IBM as part of Rational
    ClearCase, you should update the Java(TM) Virtual Machine that you use to
    include a fix for the above issues. Contact the supplier of your Java(TM)
    Virtual Machine and/or the supplier of your Eclipse shell.

CCRC WAN server fixes

+-------------------+---------------------------------------------------------+
| Affected Versions |                    Applying the fix                     |
+-------------------+---------------------------------------------------------+
|9.0.0.x            |Apply the appropriate WebSphere Application Server fix   |
|9.0.1.x            |directly to your CCRC WAN server host. No                |
|                   |ClearCase-specific steps are necessary.                  |
+-------------------+---------------------------------------------------------+

 1. Determine the WAS version used by your CCRC WAN server. Navigate to the
    CCRC profile directory (either the profile you specified when installing
    ClearCase, or <ccase-home>/common/ccrcprofile), 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 CCRC WAN
    server.

Note: there may be newer security fixes for WebSphere Application Server.

Bulletins") to subscribe to WebSphere product support alerts for additional
Java SDK fixes.
