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.

CVSS Base Score: 3.10
CVSS Temporal Score: See  https://exchange.xforce.ibmcloud.com/vulnerabilities/
136078  for the current score
CVSS Environmental Score:  *Undefined
