These issues were disclosed as part of the IBM Java SDK updates in July 2018. Vulnerability Details CVEID: CVE-2018-1656 DESCRIPTION: The IBM Java Runtime Environment's Diagnostic Tooling Framework for Java (DTFJ) does not protect against path traversal attacks when extracting compressed dump files. CVSS Base Score: 7.4 CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/ 144882 for the current score CVSS Environmental Score*: Undefined CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:R/S:C/C:N/I:H/A:N) CVEID: CVE-2018-12539 DESCRIPTION: Eclipse OpenJ9 could allow a local attacker to gain elevated privileges on the system, caused by the failure to restrict the use of Java Attach API to connect to an Eclipse OpenJ9 or IBM JVM on the same machine and use Attach API operations to only the process owner. An attacker could exploit this vulnerability to execute untrusted native code and gain elevated privileges on the system. CVSS Base Score: 8.4 CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/ 148389 for more information 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 8 and 9 in the following components: o ClearQuest Web/CQ OSLC server/CM Server component, when configured to use SSL. o 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 9.0.1.4 | Affected | +---------------------------------------+-------------------------------------+ | 9.0 through 9.0.0.6 | Affected | +---------------------------------------+-------------------------------------+ |8.0 through 8.0.0.21 |Affected | +---------------------------------------+-------------------------------------+ |8.0.1 through 8.0.1.18 |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 9.0.1.4 |Install Rational ClearQuest Fix Pack 5 (9.0.1.5) for 9.0.1 | | 9.0 through 9.0.0.6 | | +------------------------+-------------------------------------------------------------------------+ |8.0.1 through 8.0.1.18 |Install Rational ClearQuest Fix Pack 19 (8.0.1.19) for 8.0.1 | |8.0 through 8.0.0.21 | | +------------------------+-------------------------------------------------------------------------+ For 7.0, 7.1, 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 affects WebSphere Application Server July 2018 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 below (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.
