Security Bulletin: Multiple vulnerabilities in OpenSSL affect WebSphere Message
Broker , IBM Integration Bus and IBM App Connect

Security Bulletin

Document information

More support for: IBM Integration Bus

Software version: All Versions

Operating system(s): AIX, HP-UX, Linux, Solaris

Reference #: 0735561

Modified date: 21 November 2018

Summary

Multiple vulnerabilities in OpenSSL affect WebSphere Message Broker, IBM
Integration Bus and IBM App Connect. The DataDirect ODBC Drivers used by
WebSphere Message Broker , IBM App Connect and IBM Integration Bus have
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)

 

CVEID: CVE-2018-0737
DESCRIPTION: OpenSSL could allow a local attacker to obtain sensitive
information, caused by a cache-timing side channel attack in the RSA Key
generation algorithm. An attacker with access to mount cache timing attacks
during the RSA key generation process could exploit this vulnerability to
recover the private key and obtain sensitive information.
CVSS Base Score: 3.3
CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/
141679 for the current score
CVSS Environmental Score*: Undefined
CVSS Vector: (CVSS:3.0/AV:L/AC:L/PR:L/UI:N/S:U/C:L/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: 5.3
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)
