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.
