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.
