IBM Security Bulletin : Multiple vulnerabilities in IBM Java Runtime affect IBM Integration Bus and WebSphere Message Broker (CVE-2015-0138) - United States  SECURITY BULLETIN

SUMMARY
 The “FREAK: Factoring Attack on RSA-EXPORT keys" TLS/SSL client and server vulnerability affects IBM® Runtime Environment Java™ Technology Edition 6SR16 (and earlier) used by WebSphere Message Broker and the IBM® Runtime Environment Java™ Technology Edition 7SR8 (and earlier) or 7R1 (and earlier) used by IBM Integration Bus. 

VULNERABILITY DETAILS
CVEID: CVE-2015-0138 [http://cve.mitre.org/cgi-bin/cvename.cgi?name=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
