Security vulnerabilities have been discovered in the OpenSSL libraries used by IBM Sterling B2B Integrator and IBM Sterling File Gateway.
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 Version 1.0.1.
** ****CVE-ID:CVE-2013-4353 **
DESCRIPTION:
A carefully crafted invalid TLS handshake could crash OpenSSL with a NULL pointer exception. A malicious server could use this flaw to crash a connecting client. This issue only affected OpenSSL 1.0.1 versions.
The attack does not require authentication, local network access or specialized knowledge. An exploit could impact the availability of the system but the integrity of data and the confidentiality of information would not be compromised.
CVSS Base Score: 5.0
CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/90201 for the current score
CVSS Environmental Score*: Undefined

**
CVE-ID:**_ _CVE-2013-6450
DESCRIPTION:
A flaw in DTLS handling can cause an application using OpenSSL and DTLS to crash. OpenSSL versions prior to 1.0.0 are not vulnerable. OpenSSL is vulnerable to a denial of service, caused by the failure to properly maintain data structures for digest and encryption contexts by the DTLS retransmission implementation. A remote attacker could exploit this vulnerability to cause the daemon to crash.
The attack does not require authentication or local network access but some degree of specialized knowledge and techniques are required. An exploit would not impact the confidentiality of information or the integrity of data, but the availability of the system could be compromised.
CVSS Base Score: 4.3
CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/90069 for the current score

**
CVE ID: CVE-2013-6449**
DESCRIPTION:
A flaw in OpenSSL can cause an application using OpenSSL to crash when using TLS version 1.2. This issue only affected OpenSSL 1.0.1 versions. OpenSSL is vulnerable to a denial of service, caused by an error in the ssl_get_algorithm2 function. A remote attacker could exploit this vulnerability using specially-crafted traffic from a TLS 1.2 client to cause the daemon to crash.
The attack does not require authentication or local network access but some degree of specialized knowledge and techniques are required. An exploit would not impact the confidentiality of information or the integrity of data, but the availability of the system could be compromised.

*The CVSS Environment Score is customer environment specific and will ultimately impact the Overall CVSS Score. Customers can evaluate the impact of this vulnerability in their environments by accessing the links in the Reference section of this Security Bulletin.
According to the Forum of Incident Response and Security Teams (FIRST), the Common Vulnerability Scoring System (CVSS) is an “industry open standard designed to convey vulnerability severity and help to determine urgency and priority of response.” IBM PROVIDES THE CVSS SCORES ““AS IS”” WITHOUT WARRANTY OF ANY KIND, INCLUDING THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. CUSTOMERS ARE RESPONSIBLE FOR ASSESSING THE IMPACT OF ANY ACTUAL OR POTENTIAL SECURITY VULNERABILITY. In addition to other efforts to address potential vulnerabilities, IBM periodically updates the record of components contained in our product offerings. As part of that effort, if IBM identifies previously unidentified packages in a product/service inventory, we address relevant vulnerabilities regardless of CVE date. Inclusion of an older CVEID does not demonstrate that the referenced product has been used by IBM since that date, nor that IBM was aware of a vulnerability as of that date. We are making clients aware of relevant vulnerabilities as we become aware of them. “Affected Products and Versions” referenced in IBM Security Bulletins are intended to be only products and versions that are supported by IBM and have not passed their end-of-support or warranty date. Thus, failure to reference unsupported or extended-support products and versions in this Security Bulletin does not constitute a determination by IBM that they are unaffected by the vulnerability. Reference to one or more unsupported versions in this Security Bulletin shall not create an obligation for IBM to provide fixes for any unsupported or extended-support products or versions.
