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-2017-3738
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.
