Security Bulletin: Vulnerabilities in Open SSL affect Watson Explorer (CVE-2016-0701 and CVE-2015-3197)

Summary

Two vulnerabilities in OpenSSL affect Watson Explorer.

Vulnerability Details

CVEID:CVE-2016-0701
DESCRIPTION: The DH_check_pub_key function in crypto/dh/dh_check.c in OpenSSL 1.0.2 before 1.0.2f does not ensure that prime numbers are appropriate for Diffie-Hellman (DH) key exchange, which makes it easier for remote attackers to discover a private DH exponent by making multiple handshakes with a peer that chose an inappropriate number, as demonstrated by a number in an X9.42 file.
CVSS Base Score: 3.7
CVSS Temporal Score: See <https://exchange.xforce.ibmcloud.com/vulnerabilities/110234&gt;[](&lt;https://exchange.xforce.ibmcloud.com/vulnerabilities/109415&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:L/I:N/A:N)

CVEID:CVE-2015-3197
DESCRIPTION: ssl/s2_srvr.c in OpenSSL 1.0.1 before 1.0.1r and 1.0.2 before 1.0.2f does not prevent use of disabled ciphers, which makes it easier for man-in-the-middle attackers to defeat cryptographic protection mechanisms by performing computations on SSLv2 traffic, related to the get_client_master_key and get_client_hello functions.
CVSS Base Score: 5.9
CVSS Temporal Score: See <https://exchange.xforce.ibmcloud.com/vulnerabilities/110235&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)

Remediation/Fixes

Follow these steps to upgrade to the required version of OpenSSL.
The table reflects product names at the time the specified versions were released. To use the links to Fix Central in this table, you must first log in to the IBM Support: Fix Central site at <http://www.ibm.com/support/fixcentral/&gt;.

See Watson Explorer Version 11.0.0.2 Foundational Components for download information and instructions.
Watson Explorer Foundational Components| 10.0.0.0 - 10.0.0.2| Upgrade to Version 10.0.0.2 (if necessary), then apply the 10.0.0.2 interim fix.

1. If not already installed, upgrade to version 10.0.0.2. See Watson Explorer 10.0.0.2 Foundational Components for download information and instructions.

2. Download the 10.0.0.2 interim fix for your edition of Watson Explorer from Fix Central.

3. Place the interim fix zip or tar file at the root of the Watson Explorer Engine installation directory.
   Default locations:
   Linux: /opt/ibm/WEX/Engine
   Windows: \Program Files\IBM\WEX\Engine

4. Run Engine/bin/velocity-shutdown[.exe]

5. Extract all files from the archive file.

6. Linux users should change ownership on all Engine subdirectories to their Apache user and Apache user group by running chown -R apache:apache *

7. Run Engine/bin/velocity-startup[.exe]
   Watson Explorer Foundational Components | 9.0.0.0 - 9.0.0.6| Upgrade to Version 9.0.0.6 (if necessary), then apply the 9.0.0.6 interim fix.

8. If not already installed, upgrade to version 9.0.0.6. Watson Explorer 9.0.0.6 can be downloaded from Fix Central.

9. Download the 9.0.0.6 interim fix for your edition of Watson Explorer from Fix Central.

10. Place the interim fix zip or tar file at the root of the Watson Explorer Engine installation directory.
    Default locations:
    Linux: /opt/ibm/IDE
    Windows: \Program Files\IBM\IDE

11. Run Engine/bin/velocity-shutdown[.exe]

12. Extract all files from the archive file.

13. Linux users should change ownership on all Engine subdirectories to their Apache user and Apache user group by running chown -R apache:apache *

14. Run Engine/bin/velocity-startup[.exe]

Note: After installing the interim fix, the splash screen (available from Help > About) will read “9.0.0.6”, while the “Release Version” below it will read “9.0.0.7”. This discrepancy is to be expected.
InfoSphere Data Explorer| 8.2 - 8.2-4| Upgrade to Version 8.2-4, then apply the 8.2-4 interim fix.

1. If not already installed, upgrade to version 8.2-4. Watson Explorer 8.2-4 can be downloaded from Fix Central.
2. Download the 8.2-4 interim fix from Fix Central. Linux | Windows
3. Place the interim fix zip or tar file at the root of the Watson Explorer Engine installation directory.
   Default locations:
   Linux: /opt/IBM/IDE/Engine
   Windows: \Program Files\IBM\IDE
4. Run Engine/bin/velocity-shutdown[.exe]
5. Extract all files from the archive file.
6. Linux users should change ownership on all Engine subdirectories to their Apache user and Apache user group by running chown -R apache:apache *
7. Run Engine/bin/velocity-startup[.exe]

Note: After installing the interim fix, the splash screen (available from Help > About) will read “8.2-4”, while the “Release Version” below it will read “8.2-5”. This discrepancy is to be expected.
