GSKit is an IBM component that is used by Host On-Demand.The GSKit that is shipped with Host On-Demand contains multiple security vulnerabilities including the “FREAK: Factoring Attack on RSA-EXPORT keys" TLS/SSL client and server vulnerability. Host On-Demand has addressed the applicable CVEs.
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.
