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 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 for the current score
CVSS Environmental Score: *Undefined

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.
