SWIFTNet adapters of IBM Sterling B2B Integrator and IBM Sterling File Gateway use OpenSSL libraries for cryptography, and thus are affected by the following security vulnerabilities discovered in OpenSSL libraries versions 0.9.8 and 1.0.1. Vulnerability Details CVE-ID: CVE-2014-3509 DESCRIPTION: OpenSSL is vulnerable to a denial of service, caused by a race condition in the ssl_parse_serverhello_tlsext() code. If a multithreaded client connects to a malicious server using a resumed session, a remote attacker could exploit this vulnerability to cause a denial of service. CVSS Base Score: 4.3 CVSS Temporal Score: See http://xforce.iss.net/xforce/xfdb/95159 for more information CVSS Environmental Score*: Undefined CVSS Vector: (AV:N/AC:M/Au:N/C:N/I:N/A:P) CVE-ID: CVE-2014-3511 DESCRIPTION: OpenSSL could allow a remote attacker to bypass security restrictions, caused by the negotiation of TLS 1.0 instead of higher protocol versions by the OpenSSL SSL/TLS server code when handling a badly fragmented ClientHello message. An attacker could exploit this vulnerability using man-in-the-middle techniques to force a downgrade to TLS 1.0. CVSS Base Score: 4.3 CVSS Temporal Score: See http://xforce.iss.net/xforce/xfdb/95162 for more information CVSS Environmental Score*: Undefined CVSS Vector: (AV:N/AC:M/Au:N/C:N/I:P/A:N) CVE-ID: CVE-2014-3510 DESCRIPTION: OpenSSL is vulnerable to a denial of service, caused by a NULL pointer dereference in anonymous ECDH ciphersuites. A remote attacker could exploit this vulnerability using a malicious handshake to cause the client to crash. CVSS Base Score: 4.3 CVSS Temporal Score: See http://xforce.iss.net/xforce/xfdb/95164 for more information CVSS Environmental Score*: Undefined CVSS Vector: (AV:N/AC:M/Au:N/C:N/I:N/A:P) CVE-ID: CVE-2014-3508 DESCRIPTION: OpenSSL could allow a remote attacker to obtain sensitive information, caused by an error in OBJ_obj2txt. If applications echo pretty printing output, an attacker could exploit this vulnerability to read information from the stack. CVSS Base Score: 4.3 CVSS Temporal Score: See http://xforce.iss.net/xforce/xfdb/95165 for more information CVSS Environmental Score*: Undefined CVSS Vector: (AV:N/AC:M/Au:N/C:P/I:N/A:N) Affected Products and Versions IBM Sterling B2B Integrator 5.2 or IBM Sterling File Gateway 2.2 IBM Sterling B2B Integrator 5.1 or IBM Sterling File Gateway 2.1 Remediation/Fixes PRODUCT REMEDIATION/FIX IBM Sterling B2B Integrator 5.2 or SWIFTNet Customers must upgrade their IBM Sterling File Gateway 2.2 current version of OpenSSL to version 0.9.8zb or 1.0.1i IBM Sterling B2B Integrator 5.1 or SWIFTNet Customers must upgrade their IBM Sterling File Gateway 2.1 current version of OpenSSL to version 0.9.8zb Workarounds and Mitigations None Known References Complete CVSS Guide On-line Calculator V2 OpenSSL vulnerability Related information IBM Secure Engineering Web Portal IBM Product Security Incident Response Blog Change History 2 October 2014: Initial version. *The CVSS Environment Score is customer environment specific and will ultimately impact the Overall CVSS Score.
