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

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&gt; 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&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-2017-3738 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&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)

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&gt; 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&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)
