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.
