OpenSSL is used by IBM Sterling B2B Integrator. IBM Sterling B2B Integrator has addressed the applicable CVEs. Vulnerability Details CVEID: CVE-2016-2179 DESCRIPTION: OpenSSL is vulnerable to a denial of service. By sending specially crafted DTLS record fragments to fill up buffer queues, a remote attacker could exploit this vulnerability to open a large number of simultaneous connections and consume all available memory resources. CVSS Base Score: 5.3 CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/116343 for the current score CVSS Environmental Score*: Undefined CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:L) CVEID: CVE-2016-2181 DESCRIPTION: OpenSSL is vulnerable to a denial of service, caused by an error in the DTLS replay protection implementation. By sending a specially crafted sequence number, a remote attacker could exploit this vulnerability to cause valid packets to be dropped. CVSS Base Score: 5.3 CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/116344 for the current score CVSS Environmental Score*: Undefined CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:L) CVEID: CVE-2016-6304 DESCRIPTION: OpenSSL is vulnerable to a denial of service, caused by multiple memory leaks in t1_lib.c during session renegotiation. By sending an overly large OCSP Status Request extension, a remote attacker could exploit this vulnerability to consume all available memory resources. CVSS Base Score: 7.5 CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/117110 for the current score CVSS Environmental Score*: Undefined CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H) CVEID: CVE-2016-2183 DESCRIPTION: OpenSSL could allow a remote attacker to obtain sensitive information, caused by an error in the in the Triple-DES on 64-bit block cipher, used as a part of the SSL/TLS protocol. By capturing large amounts of encrypted traffic between the SSL/TLS server and the client, a remote attacker able to conduct a man-in-the-middle attack could exploit this vulnerability to recover the plaintext data and obtain sensitive information. This vulnerability is known as the SWEET32 Birthday attack. CVSS Base Score: 3.7 CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/116337 for the current score CVSS Environmental Score*: Undefined CVSS Vector: (CVSS:3.0/AV:N/AC:H/PR:N/UI:N/S:U/C:L/I:N/A:N) Affected Products and Versions IBM Sterling B2B Integrator 5.2 Remediation/Fixes Product & Version Remediated Fix IBM Sterling B2B Integrator 5.2 SWIFTNet Customers must upgrade their current version of OpenSSL to version 1.0.1u Workarounds and Mitigations None Get Notified about Future Security Bulletins Subscribe to My Notifications to be notified of important product support alerts like this.
