Reference #: 2015215
Modified date: 20 April 2018
Summary
OpenSSL vulnerabilities were disclosed on November 02, 2017 by the OpenSSL
Project. OpenSSL is used by IBM InfoSphere Information Server. IBM InfoSphere
Information Server has addressed the applicable CVEs.
Vulnerability Details
CVEID: CVE-2017-3735
DESCRIPTION: OpenSSL could allow a remote attacker to obtain sensitive
information, caused by an error while parsing an IPAdressFamily extension in an
X.509 certificate. An attacker could exploit this vulnerability to trigger an
out-of-bounds read, resulting in an incorrect text display of the certificate.
CVSS Base Score: 4.3
CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/
131047 for the current score
CVSS Environmental Score*: Undefined
CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:R/S:U/C:L/I:N/A:N)
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: 5.9
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-2017-3738
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: 3.1
CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/
136078 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)
