Summary
Vulnerabilities have been addressed in the GSKit component of IBM Rational
ClearQuest.
Vulnerability Details
CVEID: CVE-2016-0702
DESCRIPTION: OpenSSL could allow a local attacker to obtain sensitive
information, caused by a side-channel attack against a system based on the
Intel Sandy-Bridge microarchitecture. An attacker could exploit this
vulnerability to recover RSA keys.
CVSS Base Score: 2.9
CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/
111144 for the current score
CVSS Environmental Score*: Undefined
CVSS Vector: (CVSS:3.0/AV:L/AC:H/PR:N/UI:N/S:U/C:L/I:N/A:N)
CVEID: CVE-2018-1447
DESCRIPTION: The GSKit CMS KDB logic fails to salt the hash function resulting
in weaker than expected protection of passwords. A weak password may be
recovered. Note: After update the customer should change password to ensure
the new password is stored more securely. Products should encourage customers
to take this step as a high priority action.
CVSS Base Score: 5.1
CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/
139972 for the current score
CVSS Environmental Score*: Undefined
CVSS Vector: (CVSS:3.0/AV:L/AC:H/PR:N/UI:N/S:U/C:H/I:N/A:N)
CVEID: CVE-2018-1427
DESCRIPTION:IBM GSKit contains several environment variables that a local
attacker could overflow and cause a denial of service.
CVSS Base Score: 6.2
CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/
139072 for the current score
CVSS Environmental Score*: Undefined
CVSS Vector: (CVSS:3.0/AV:L/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H)
CVEID: CVE-2016-0705
DESCRIPTION:OpenSSL is vulnerable to a denial of service, caused by a
double-free error when parsing DSA private keys. An attacker could exploit
this vulnerability to corrupt memory and cause a denial of service.
CVSS Base Score: 3.7
CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/

Remediation/Fixes
Note: After applying the fixes as noted below, please refer to this document
http://publib.boulder.ibm.com/httpserv/ihsdiag/restash.html for information
concerning password re-stashing. It is advised that you re-stash your password
due to CVE-2018-1447 after you apply the fixes.
The solution is to upgrade to a newer fix pack or release of ClearQuest, and
to apply fixes for IBM HTTP Server (IHS).
+--------------------+-------------------------------------------------------+
| Affected Versions | Fixes |
+--------------------+-------------------------------------------------------+
| 9.0.1 through |Install Rational ClearQuest Fix Pack 3 (9.0.1.3) for |
| 9.0.1.2 |9.0.1 |
|9.0 through 9.0.0.6 | |
+--------------------+-------------------------------------------------------+
| 8.0.1 through |Install Rational ClearQuest Fix Pack 17 (8.0.1.17) for |
| 8.0.1.16 |8.0.1 |
|8.0 through 8.0.0.21| |
+--------------------+-------------------------------------------------------+
ClearQuest CM Server:
Apply an IHS fix for the issue:
1. Determine the IHS version used by your ClearQuest CM server. Navigate to
the IBM HTTP Server installation directory (typically /opt/ibm/HTTPServer
or C:\Program Files (x86)\IBM\HTTPServer), then execute the script: bin/
versionInfo.sh (UNIX) or bin\versionInfo.bat (Windows). The output
includes a section "IBM HTTP Server for WebSphere Application Server".
Make note of the version listed in this section.
2. Review the following IHS security bulletin for the available fixes:
Security Bulletin: Multiple vulnerabilities GSKit bundled with IBM HTTP
Server. Note: there may be newer security fixes for IBM HTTP Server.
Follow the link above (in the section "Get Notified about Future Security
Bulletins") to subscribe to WebSphere product support alerts for
additional security fixes.
3. Apply the relevant fixes to your IBM HTTP Server installation used on your
ClearQuest CM server host. No ClearQuest-specific steps are necessary
For 7.0, 7.1, 8.0, and earlier releases, IBM recommends upgrading to a fixed,
supported version/release/platform of the product.
