Summary

The FREAK: Factoring Attack on RSA-EXPORT keys" TLS/SSL client and server 
vulnerability affects IBM SDK Java Technology Edition, Version 5, 6 and 7 that
is used by Rational Service Tester related to the use of TLS/SSL.

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.
