This includes FREAK: Factoring Attack on RSA-EXPORT keys" TLS/SSL client and server vulnerability. OpenSSL is used by Connect:Direct for HP NonStop. Connect:Direct for HP NonStop has addressed the applicable CVEs. Vulnerability Details CVEID: CVE-2014-3570 DESCRIPTION: An unspecified error in OpenSSL related to the production of incorrect results on some platforms by Bignum squaring (BN_sqr) has an unknown attack vector and impact. CVSS Base Score: 2.6 CVSS Temporal Score: See http://xforce.iss.net/xforce/xfdb/99710 for the current score CVSS Environmental Score*: Undefined CVSS Vector: (AV:N/AC:H/Au:N/C:N/I:P/A:N) 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. CVSS Base Score: 4.3 CVSS Temporal Score: See http://xforce.iss.net/xforce/xfdb/99707 for the current score CVSS Environmental Score*: Undefined CVSS Vector: (AV:N/AC:M/Au:N/C:N/I:P/A:N) Affected Products and Versions IBM Sterling Connect:Direct for HP NonStop 3.5.00 IBM Sterling Connect:Direct for HP NonStop 3.5.01 IBM Sterling Connect:Direct for HP NonStop 3.6.0 Remediation/Fixes The recommended solution is to apply the fix as soon as practical.
