The GSKit that is shipped with IBM Rational RequisitePro contains multiple security vulnerabilities including the FREAK: Factoring Attack on RSA-EXPORT keys" TLS/SSL client and server vulnerability. IBM Rational RequisitePro has addressed the applicable CVEs. Vulnerability Details CVEID: CVE-2015-0138 DESCRIPTION: A vulnerability in various IBM SSL/TLS implementations could allow a remote attacker to downgrade the security of certain SSL/TLS connections. An IBM SSL/TLS client implementation could accept 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/100691 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 Version Status 7.1.4 through 7.1.4.7 Affected 7.1.3 through 7.1.3.14 Affected 7.1.1.x, 7.1.2.x (all versions) Affected You are vulnerable if you configure Rational RequisitePro to use LDAP authentication with secure socket connections. Remediation/Fixes The fix is to first upgrade ReqPro to 7.1.2.17, 7.1.3.14, or 7.1.4.7. If installing 7.1.3.14 or 7.1.4.7, then a second step is required, installing a newer version of the GSKit component that fixes the vulnerability. Contact Rational Customer Support for a copy of the fix and the instructions to manually patch your system(s). 2) If upgrading to 7.1.3.14, or 7.1.4.7, then contact Rational Customer support for instructions to download and install the GSKit fix. If you are upgrading to 7.1.2.17, then you are done. You should verify applying this fix does not cause any compatibility issues.
