OpenSSl is used by IBM Sterling Connect:Express for UNIX. IBM Sterling Connect:Express for UNIX has addressed the applicable CVEs. Vulnerability Details CVE-ID: CVE-2017-3736 Description: OpenSSL could allow a remote attacker to obtain sensitive information, caused by a carry propagation flaw in the the x86_64 Montgomery squaring function bn_sqrx8x_internal(). An attacker with online access to an unpatched system could exploit this vulnerability to obtain information about the private key. CVSS Base Score: 5.9 CVSS Temporal Score: https://exchange.xforce.ibmcloud.com/vulnerabilities/ 134397 for more information CVSS Environmental Score*: Undefined CVSS Vector: (CVSS:3.0/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:N/A:N) CVE-ID: CVE-2017-3737 Description: An unspecified vulnerability in multiple Oracle products could allow an unauthenticated attacker to cause low confidentiality impact, low integrity impact, and high availability impact. CVSS Base Score: 5.3 CVSS Temporal Score: https://exchange.xforce.ibmcloud.com/vulnerabilities/ 136077 for more informationCVSS Environmental Score*: Undefined CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:L/A:N) CVE-ID: CVE-2017-3736 Description: OpenSSL could allow a remote attacker to obtain sensitive information, caused by an overflow bug in the AVX2 Montgomery multiplication procedure used in exponentiation with 1024-bit moduli. An attacker could exploit this vulnerability to obtain information about the private key. Note: In order to exploit this vulnerability, the server would have to share the DH1024 private key among multiple clients, which is no longer an option since CVE-2016-0701.
