Security Bulletin: Vulnerability with RSA Export Keys affects IBM Systems Director (CVE-2015-0138)

Vulnerability Details

Abstract

The FREAK: Factoring Attack on RSA-EXPORT keys TLS/SSL client and server vulnerability affects IBM Systems Director.

Content

Vulnerability Details:

CVE-ID: 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.
