Vulnerability Details
CVEID: CVE-2016-5546
DESCRIPTION: An unspecified vulnerability related to the Libraries component has no confidentiality impact, high integrity impact, and no availability impact.
CVSS Base Score: 7.5
CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/120869 for the current score
CVSS Environmental Score*: Undefined

CVEID: CVE-2016-5548
DESCRIPTION: An unspecified vulnerability related to the Libraries component could allow a remote attacker to obtain sensitive information resulting in a high confidentiality impact using unknown attack vectors.
CVSS Base Score: 6.5
CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/120864 for the current score
CVSS Environmental Score*: Undefined
CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:N/A:N)
CVEID: CVE-2016-5549
DESCRIPTION: An unspecified vulnerability related to the Libraries component could allow a remote attacker to obtain sensitive information resulting in a high confidentiality impact using unknown attack vectors.
CVSS Base Score: 6.5
CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/120863 for the current score
CVSS Environmental Score*: Undefined
CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:N/A:N)
CVEID: CVE-2016-5547
DESCRIPTION: An unspecified vulnerability related to the Libraries component could allow a remote attacker to cause a denial of service resulting in a low availability impact using unknown attack vectors.
CVSS Base Score: 5.3
CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/120871 for the current score
CVSS Environmental Score*: Undefined
CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:L)
CVEID: CVE-2016-2183
DESCRIPTION: OpenSSL could allow a remote attacker to obtain sensitive information, caused by an error in the DES/3DES cipher, used as a part of the SSL/TLS protocol. By capturing large amounts of encrypted traffic between the SSL/TLS server and the client, a remote attacker able to conduct a man-in-the-middle attack could exploit this vulnerability to recover the plaintext data and obtain sensitive information. This vulnerability is known as the SWEET32 Birthday attack.
CVSS Base Score: 3.7
CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/116337 for the current score
CVSS Environmental Score*: Undefined
CVSS Vector: (CVSS:3.0/AV:N/AC:H/PR:N/UI:N/S:U/C:L/I:N/A:N)
Affected Products and Versions
- 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, 9.0.1.1 | Not Affected |
9.0 through 9.0.0.4 | Affected |
8.0.1 through 8.0.1.14 | Affected |
8.0 through 8.0.0.21 | Affected |
7.1.2 through 7.1.2.19 (all fix packs) | Affected |
Remediation/Fixes
The solution is to install a fix that includes an updated Java™ Virtual Machine with fixes for the issues, and to apply fixes for WebSphere Application Server (WAS).
ClearQuest Web/CQ OSLC Server/CM Server Component
- 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.
- Review the following WAS security bulletin:
Security Bulletin: Multiple vulnerabilities in IBM® Java SDK affects WebSphere Application Server January 2017 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 |
| 8.0.0.x 8.0.1.x 9.0.0.x | Apply the appropriate WebSphere Application Server fix directly to your CM server host. No ClearQuest-specific steps are necessary. |
| 7.1.2.x (all fix packs) 7.1.1.x (all fix packs) 7.1.0.x (all fix packs) | Customers should upgrade to a fixed, supported version/release of the product. |
ClearQuest Eclipse Clients
Apply the relevant fixes as listed in the table below.
Affected Versions | Applying the fix |
9.0 through 9.0.0.4 | Install Rational ClearQuest Fix Pack 5 (9.0.0.5) for 9.0 or install Rational ClearQuest release 9.0.1 |
8.0.1 through 8.0.1.14 8.0 through 8.0.0.21 | Install Rational ClearQuest Fix Pack 15 (8.0.1.15) for 8.0.1 |
7.1.2 through 7.1.2.19 (all fix packs) | Customers should upgrade to a fixed, supported version/release of the product. |
