Security Bulletin


Summary

GSKit is an IBM component that is used by IBM Rational RequisitePro. 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

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 If installing 7.1.3.14 or 7.1.4.7, then a second step is required, installing a newer version of the GSKit component that fixes the vulnerability.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). The GSKit release with the fix can be located in Fix Central.

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.
