This includes "FREAK: Factoring Attack on RSA-EXPORT keys" TLS/SSL client and server vulnerability. OpenSSL is used by ratlperl for SSL communications. Rational RequisitePro 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 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 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 CVSS Environmental Score*: Undefined CVSS Vector: (AV:N/AC:M/Au:N/C:N/I:P/A:N) Affected Products and Versions IBM Rational RequisitePro versions: Version Status 7.1.4 through 126.96.36.199 Affected 7.1.3 through 188.8.131.52 Affected 7.1.2 through 184.108.40.206 Affected 7.1.1.x (all versions) Affected Not all deployments of Rational RequisitePro use OpenSSL in a way that is affected by these vulnerabilities. You are vulnerable if your use of Rational RequisitePro includes any of these configurations: 1. You use SSL connections in perl scripts run by ratlperl or cqperl 2. You integrate with ClearQuest. See Security Bulletin: Vulnerabilities in OpenSSL affect Rational ClearQuest (CVE-2014-3570, CVE-2014-3572, CVE-2015-0204) Remediation/Fixes The fix is to upgrade RequisitePro to 220.127.116.11, 18.104.22.168, or 22.214.171.124 and install OpenSSL 1.0.1l for IBM Rational RequisitePro. Upgrade RequisitePro: Affected version Applying the fix 7.1.4.x (all versions) Install Rational RequisitePro Fix Pack 7 (126.96.36.199) 7.1.3.x (all versions) Install Rational RequisitePro Fix Pack 14 (188.8.131.52) 7.1.2.x (all versions) Install Rational RequisitePro Fix Pack 17 (184.108.40.206). and 7.1.1.x (all Note: 220.127.116.11 interoperates with all 7.1.x.x systems, versions) and can be installed in the same way as 7.1.x.x fix packs. Contact Rational Customer support for instructions to download and install the updated version of OpenSSL. You should verify applying this fix does not cause any compatibility issues. Workarounds and Mitigations Disable any script that uses SSL and runs in ratlperl or cqperl until you apply the fixes listed above.
