Security Bulletin: Multiple vulnerabilities in IBM Java SDK affect Rational Developer for i, Rational Developer for AIX and Linux, and Rational Developer for Power Systems Software (CVE-2015-0138, CVE-2015-0410, CVE-2015-0400, CVE-2014-6593)

Summary

There are multiple vulnerabilities in IBM® SDK Java™ Technology Edition, Version 6 and 7 that are used by Rational Developer for i, Rational Developer for AIX and Linux, and Rational Developer for Power Systems Software. These issues were disclosed as part of the IBM Java SDK updates in January 2015. This bulletin also addresses the “FREAK: Factoring Attack on RSA-EXPORT keys" TLS/SSL client and server vulnerability.

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.
