Summary
OpenSSL is used by IBM Netezza Host Management. IBM Netezza Host Management has addressed the applicable CVEs.
Vulnerability Details
CVEID: CVE-2016-2183
DESCRIPTION: OpenSSL could allow a remote attacker to obtain sensitive information, caused by an error in the DES/3DES cipher, used as a part of the SSL/TLS protocol. By capturing large amounts of encrypted traffic between the SSL/TLS server and the client, a remote attacker able to conduct a man-in-the-middle attack could exploit this vulnerability to recover the plaintext data and obtain sensitive information. This vulnerability is known as the SWEET32 Birthday attack.
CVSS Base Score: 3.7
CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/116337 for the current score
CVSS Environmental Score*: Undefined
CVSS Vector: (CVSS:3.0/AV:N/AC:H/PR:N/UI:N/S:U/C:L/I:N/A:N)
Affected Products and Versions
- IBM Netezza Host Management 5.4.2.1 - 5.4.9.0
Remediation/Fixes
To resolve the reported CVE for Red Hat Enterprise Linux (RHEL) on PureData System for Analytics N200x and N3001 platforms only, update to the following IBM Netezza Host Management release:

Workarounds and Mitigations
Mitigation of the reported CVE for Red Hat Enterprise Linux (RHEL) applies to the following platforms only:
PureData System for Analytics N1001
IBM Netezza High Capacity Appliance C1000
IBM Netezza 1000
IBM Netezza 100
Step 1. On each host, determine the location and OpenSSL version installed:
[host]# which openssl
/usr/bin/openssl
[host]# ldd /usr/bin/openssl
libssl.so.4 => /lib64/libssl.so.4
libcrypto.so.4 => /lib64/libcrypto.so.4
Step 2. On each host, determine the installed library version:
[host]# ll /lib64/libssl.so.4
lrwxrwxrwx 1 root root 16 Jul 27 2016 /lib64/libssl.so.4 -> libssl.so.0.9.7a
OR
[host]# ll /lib64/libssl.so.6
lrwxrwxrwx 1 root root 16 Jul 27 2016 /lib64/libssl.so.6 -> libssl.so.0.9.8e
Step 3. If output of step 2 shows:
0.9.7a – Please refer to article 1615012 to upgrade your IBM Netezza appliance.
0.9.8e – Please perform the following steps:
A. On each host, determine the installed OpenSSL RPM version:
[host]# rpm -qa | grep openssl
openssl-fips-1.0.1e-39
openssl-libs-1.0.1e-39
openssl-libs-1.0.1e-39
openssl-fips-1.0.1e-39
C. If OpenSSL library version is 1.0.2j or later, the mitigation is in place.
