This includes FREAK: Factoring Attack on RSA-EXPORT keys" TLS/SSL client and server vulnerability. OpenSSL is used by IBM Sterling Connect:Direct for UNIX. IBM Sterling Connect:Direct for UNIX 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://exchange.xforce.ibmcloud.com/#/vulnerabilities/99710 or 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://exchange.xforce.ibmcloud.com/#/vulnerabilities/99707 for the current score CVSS Environmental Score*: Undefined CVSS Vector: (AV:N/AC:M/Au:N/C:N/I:P/A:N) CVEID: CVE-2015-0205 DESCRIPTION: OpenSSL could allow a remote authenticated attacker to bypass security restrictions, caused by the acceptance of a DH certificate for client authentication without verification. An attacker could exploit this vulnerability to authenticate without the use of a private key.

The GSKit that is shipped with IBM Sterling Connect:Direct for UNIX contains multiple security vulnerabilities including the FREAK: Factoring Attack on RSA-EXPORT keys" TLS/SSL client and server vulnerability. IBM Sterling Connect:Direct for UNIX has addressed the applicable CVEs. Vulnerability Details CVEID: CVE-2015-0159 DESCRIPTION: An unspecified error in GSKit usage of OpenSSL crypto function related to the production of incorrect results on some platforms by Bignum squaring (BN_sqr) has an unknown attack vector and impact in some ECC operations. CVSS Base Score: 2.6 CVSS Temporal Score: See http://exchange.xforce.ibmcloud.com/#/vulnerabilities/100835 for the current score CVSS Environmental Score*: Undefined CVSS Vector: (AV:N/AC:H/Au:N/C:N/I:P/A:N) CVEID: CVE-2015-0138 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.
