and 8, which are used by IBM Rational ClearQuest. These issues were disclosed
as part of the IBM Java SDK updates in January 2019.
Vulnerability Details
CVEID: CVE-2018-1890
DESCRIPTION: IBM SDK, Java Technology Edition Version 8 on the AIX platform
uses absolute RPATHs which may facilitate code injection and privilege
elevation by local users.
CVSS Base Score: 5.6
CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/
152081 for the current score
CVSS Environmental Score*: Undefined

CVEID: CVE-2018-12547
DESCRIPTION: Eclipse OpenJ9 is vulnerable to a buffer overflow, caused by
improper bounds checking by the jio_snprintf() and jio_vsnprintf() functions.
By sending an overly long argument, a remote attacker could overflow a buffer
and execute arbitrary code on the system or cause the application to crash.
CVSS Base Score: 9.8
CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/

Affected Products and Versions
IBM Rational ClearQuest version 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 9.0.1.6 | Affected |
+---------------------------------------+-------------------------------------+
| 9.0 through 9.0.0.6 | Affected |
+---------------------------------------+-------------------------------------+
Remediation/Fixes
The solution for version 9 AIX, Solaris and Windows is to install a fix that
includes an updated Java(TM) Virtual Machine, 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 9.0.1.6 |Install Rational ClearQuest Fix Pack 7 (9.0.1.7) for 9.0.1 |
| 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 January 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. |
+-------------------+---------------------------------------------------------+
Workarounds and Mitigations
None.
