Security Bulletin
Summary
The “FREAK: Factoring Attack on RSA-EXPORT keys" TLS/SSL client and server vulnerability affects IBM SDK Java Technology Edition, Version 6 and IBM SDK Java Technology Edition, Version 7 that is used by IBM OS Images for Red Hat Linux Systems, AIX, and Windows.
Vulnerability Details
CVEID: CVE-2015-0138
DESCRIPTION: A vulnerability in various IBM SSL/TLS implementations could allow a remote attacker to downgrade the security of certain SSL/TLS connections. An IBM SSL/TLS client implementation could accept the use of an RSA temporary key in a non-export RSA key exchange ciphersuite. This could allow a remote attacker using man-in-the-middle techniques to facilitate brute-force decryption of TLS/SSL traffic between vulnerable clients and servers.
This vulnerability is also known as the FREAK attack.
CVSS Base Score: 4.3
CVSS Temporal Score: See http://exchange.xforce.ibmcloud.com/#/vulnerabilities/100691 for the current score
CVSS Environmental Score*: Undefined
CVSS Vector: (AV:N/AC:M/Au:N/C:N/I:P/A:N)
Affected Products and Versions
IBM OS Image for Red Hat Linux Systems 2.0.0.1 and earlier.
IBM OS Image for AIX 2.0.0.1 and earlier.
IBM OS Image for Windows 2.0.0.1 and earlier.
Remediation/Fixes
The deployed Red Hat Linux-based, AIX, and Windows virtual machines on all IBM PureApplication Systems types are affected. The solution is to apply the following IBM PureApplication System fix to the deployed virtual machines.

- Import the fix into the Emergency Fix catalogue.
- For deployed instances, apply this emergency fix on the VM. The IBM Java SDK will be upgraded to IBM Java JDK 7.0 SR8 FP10 interim fix and IBM Java JDK 6.0 SR16 FP3 interim fix.
- Restart the deployed instance after the fix is applied.
You should verify applying this fix does not cause any compatibility issues.
