Summary

Open Source OpenSSL Vulnerabilities

Vulnerability Details

CVEID: 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&gt; 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

CVEID: 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&gt; 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

CVEID: 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. **CVSS Base Score:**3.10 **CVSS Temporal Score:**See <https://exchange.xforce.ibmcloud.com/vulnerabilities/136078&gt; for the current score **CVSS Environmental Score:***Undefined **CVSS Vector:**CVSS:3.0/AV:N/AC:H/PR:L/UI:N/S:U/C:L/I:N/A:N
