Security Bulletin: Multiple vulnerabilities in OpenSSL affect IBM Flex System Manager (FSM) Storage Manager Install Anywhere (SMIA) configuration tool (CVE-2017-3738, CVE-2017-3737)

Summary

Multiple vulnerabilities have been discovered in OpenSSL that was used by IBM FSM SMIA configuration tool (commonly known as Network Advisor). This bulletin addresses these vulnerabilities.

Vulnerability Details

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-2017-3737**
DESCRIPTION:** OpenSSL could allow a remote attacker to bypass security restrictions, caused by a flaw in the "error state" mechanism when directly calling SSL_read() or SSL_write() for an SSL object after receiving a fatal error. An attacker could exploit this vulnerability to bypass the decryption or encryption process and perform unauthorized actions.
CVSS Base Score: 5.3
CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/136077 for the current score
CVSS Environmental Score*: Undefined

Remediation/Fixes

IBM recommends updating the FSM SMIA configuration tool using the instructions referenced in this table.

IMPORTANT: Before installing a SMIA iFix you need to determine the version that is currently installed. To determine the SMIA version level installed on the FSM log into your FSM Web-based UI and navigate to the Home page and Applications tab. The version is listed next to the “SMIA Configuration Tool” link.

• If your SMIA version is less than 14.0.2, update your FSM using the instructions listed in this Security Bulletin (<http://www-01.ibm.com/support/docview.wss?uid=isg3T1024508&gt;), restart the FSM and then install the iFix listed in this table.
• If your version is 14.0.2 or greater, then install the iFix listed in this table.
