(CVE-2017-3736, CVE-2017-3737, CVE-2017-3738) Security Bulletin Summary Open Source OpenSSL Vulnerabilities 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 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: 5.90 CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/ 134397 for the current score 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: 5.30 CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/ 136077 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:L/A:N CVE ID: CVE-2017-3738 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.
