Security Bulletin: Vulnerability in OpenSSL affects IBM® DB2® LUW (CVE-2015-0204)

Summary

OpenSSL vulnerabilities were disclosed on January 8, 2015 by the OpenSSL Project. This includes “FREAK: Factoring Attack on RSA-EXPORT keys" TLS/SSL client and server vulnerability. OpenSSL is used by IBM DB2 LUW. IBM DB2 LUW has addressed the applicable CVEs.

Vulnerability Details

CVEID: CVE-2015-0204

DESCRIPTION: A vulnerability in the OpenSSL ssl3_get_key_exchange function could allow a remote attacker to downgrade the security of certain TLS connections. An OpenSSL client accepts 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.
