This includes "FREAK: Factoring Attack on RSA-EXPORT keys" TLS/SSL client and server vulnerability. OpenSSL is used by Sterling Connect:Enterprise for UNIX. Sterling Connect:Enterprise for UNIX has addressed the applicable CVEs. Vulnerability Details CVEID: CVE-2014-3569 DESCRIPTION: OpenSSL is vulnerable to a denial of service, caused by the failure to properly handle attempts to use unsupported protocols by the ssl23_get_client_hello function in s23_srvr.c. A remote attacker could exploit this vulnerability using an unexpected handshake to trigger a NULL pointer dereference and cause the daemon to crash. CVSS Base Score: 5 CVSS Temporal Score: See http://xforce.iss.net/xforce/xfdb/99706 for the current score CVSS Environmental Score*: Undefined CVSS Vector: (AV:N/AC:L/Au:N/C:N/I:N/A:P) 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) 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-2014-3572 DESCRIPTION: OpenSSL could provide weaker than expected security. The client accepts a handshake using an ephemeral ECDH ciphersuite with the server key exchange message omitted. An attacker could exploit this vulnerability to launch further attacks on the system. CVSS Base Score: 1.2 CVSS Temporal Score: See http://xforce.iss.net/xforce/xfdb/99705 for the current score CVSS Environmental Score*: Undefined CVSS Vector: (AV:L/AC:H/Au:N/C:N/I:P/A:N) CVEID: CVE-2014-8275 DESCRIPTION: OpenSSL could allow a local attacker to bypass security restrictions, caused by the modification of the fingerprint without breaking the signature. An attacker could exploit this vulnerability using non-DER or invalid encodings outside the signed portion of a certificate bypass security restrictions and perform unauthorized actions. CVSS Base Score: 1.2 CVSS Temporal Score: See http://xforce.iss.net/xforce/xfdb/99709 for the current score CVSS Environmental Score*: Undefined CVSS Vector: (AV:L/AC:H/Au:N/C:N/I:P/A:N) Affected Products and Versions Sterling Connect:Enterprise For UNIX (CEU) 184.108.40.206 through 220.127.116.11 iFix 6 Sterling Connect:Enterprise For UNIX (CEU) 18.104.22.168 through 22.214.171.124 iFix 2 Remediation/Fixes Product / VRMF Fix Where to acquire the fix Sterling Connect:Enterprise For UNIX 126.96.36.199 iFix 7 Fix available on Fix Central Sterling Connect:Enterprise For UNIX 188.8.131.52 iFix 3 Fix available on IWM You should verify applying this fix does not cause any compatibility issues.
