Security Bulletin
Summary
OpenSSL vulnerabilities were disclosed on January 8, 2015 by the OpenSSL Project. This includes “FREAK: Factoring Attack on RSA-EXPORT keys" TLS/SSL client and server vulnerability. OpenSSL is used by cqperl and ratlperl for SSL communications. Rational ClearQuest has addressed the applicable CVEs.
Vulnerability Details
CVEID: CVE-2014-3570
DESCRIPTION: An unspecified error in OpenSSL related to the production of incorrect results on some platforms by Bignum squaring (BN_sqr) has an unknown attack vector and impact.
CVSS Base Score: 2.6
CVSS Temporal Score: See http://exchange.xforce.ibmcloud.com/#/vulnerabilities/99710 for the current score
CVSS Environmental Score*: Undefined
CVSS Vector: (AV:N/AC:H/Au:N/C:N/I:P/A:N)
CVEID: CVE-2014-3572
DESCRIPTION: OpenSSL could provide weaker than expected security. The client accepts a handshake using an ephemeral ECDH ciphersuite with the server key exchange message omitted. An attacker could exploit this vulnerability to launch further attacks on the system.
CVSS Base Score: 1.2
CVSS Temporal Score: See http://exchange.xforce.ibmcloud.com/#/vulnerabilities/99705 for the current score
CVSS Environmental Score*: Undefined
CVSS Vector: (AV:L/AC:H/Au:N/C:N/I:P/A:N)
CVEID: CVE-2015-0204
DESCRIPTION: A vulnerability in the OpenSSL ssl3_get_key_exchange function could allow a remote attacker to downgrade the security of certain TLS connections. An OpenSSL client accepts the use of an RSA temporary key in a non-export RSA key exchange ciphersuite. This could allow a remote attacker using man-in-the-middle techniques to facilitate brute-force decryption of TLS/SSL traffic between vulnerable clients and servers.
This vulnerability is also known as the FREAK attack.
CVSS Base Score: 4.3
CVSS Temporal Score: See http://exchange.xforce.ibmcloud.com/#/vulnerabilities/99707 for the current score
CVSS Environmental Score*: Undefined
CVSS Vector: (AV:N/AC:M/Au:N/C:N/I:P/A:N)
Affected Products and Versions
IBM Rational ClearQuest versions:
Version | Status |
8.0.1 through 8.0.1.7 | Affected |
8.0 through 8.0.0.14 | Affected |
7.1.2.x (all versions) | Affected |
Not all deployments of Rational ClearQuest use OpenSSL in a way that is affected by these vulnerabilities.
You are vulnerable if your use of Rational ClearQuest includes any of these configurations:
- You use SSL connections in perl scripts run by ratlperl or cqperl, or by ClearQuest hooks. In this situation, you should review all the fixes provided by the OpenSSL project to see which ones apply to your use of OpenSSL. See the references link below.
- You integrate with ClearCase. See Security Bulletin: Vulnerabilities in OpenSSL affect Rational ClearCase (CVE-2014-3570, CVE-2014-3572, CVE-2015-0204)
Remediation/Fixes
The solution is to update to the latest fix pack.
Affected Versions | Applying the fix |
8.0.1.x | |
8.0.0.x | |
7.1.2.x | Customers with extended support contracts should install Rational ClearQuest Fix Pack 18 (7.1.2.18) |
You should verify applying this fix does not cause any compatibility issues.
Workarounds and Mitigations
Disable the any script that uses SSL and runs in ratlperl, cqperl or ClearQuest hooks until you apply the fixes listed above.

* 20 March 2015: Original copy published
* 24 June 2015: fix is now included in fix packs

Review the IBM security bulletin disclaimer and definitions regarding your responsibilities for assessing potential impact of security vulnerabilities to your environment.
Internal Use Only
The fixes are on the test fix portal, included in the following TestFixes:
7.1.2.17.001
8.0.0.14.001
8.0.1.07.003
they can be installed using Installation Manager.
For 2015B, we revisedthe instructions to apply a fix pack instead
The test fixes and fixpacks above supersede the previous manually-installed solution, which was:
The fixes are LA iFixes that apply on top of the 2015A fix packs
(7.1.2.17, 8.0.0.14, 8.0.1.7). Customers should upgrade to those
releases before applying these fixes.
For each platform, for each affected release, there is a zip file on the
Rational fix portal with the fixes, and a matching README file with
manual installation instructions. The customer should download the
fixes and READMEs for their platform(s)/release(s).
The plan is to incorporate all these fixes in 2015B fix packs, but we
are publishing them early to meet the IBM security team's guidelines.
