Summary
There are multiple vulnerabilities in IBM Runtime Environment Java Technology
Edition, Version 7 that is used by IBM Sterling Secure Proxy and IBM Sterling
External Authentication Server. These issues were disclosed as part of the IBM
Java SDK updates in January 2015. This bulletin also addresses the FREAK:
Factoring Attack on RSA-EXPORT keys" TLS/SSL client and server vulnerability.
Vulnerability Details
CVEID: CVE-2015-0410
DESCRIPTION: An unspecified vulnerability related to the Security component
could allow a remote attacker to cause a denial of service.
CVSS Base Score: 5
CVSS Temporal Score: See
http://exchange.xforce.ibmcloud.com/#/vulnerabilities/100151 for the current
score
CVSS Environmental Score*: Undefined
CVSS Vector: (AV:N/AC:L/Au:N/C:N/I:N/A:P)
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

Sterling Secure Proxy 3.4.2.0 APAR IT07778 Fix Central - 3.4.2.0
Sterling Secure Proxy 3.4.1.8 APAR IT07778 Fix Central - 3.4.1.8
Sterling Secure Proxy 3.4.0.6 APAR IT07778 Fix Central - 3.4.0.6
Sterling Secure Proxy 3.3.1.23 APAR IT07778 Fix available on IWM
Sterling External Authentication Server 2.4.2.0 APAR IT07778 Fix Central - 2.4.2.0
Sterling External Authentication Server 2.4.1.8 APAR IT07778 Fix Central - 2.4.1.8
Sterling External Authentication Server 2.4.0.4 APAR IT07778 Fix Central - 2.4.0.4
Sterling External Authentication Server 2.3.1.11 APAR IT07778 Fix available on IWM
The APAR fixes above include an upgrade of the Java Runtime Environment only,
with instructions on how to install it in the Customer's environment. This
brings the Java Runtime Environment to the Java 1.7 SR8 FP10 plus IV70681 APAR
fix level. Alternately, the Customer may check the fixlist of the latest iFix
cumulative maintenance package on Fix Central to see if it includes this level
of Java. If not, the Customer may contact Support to request that the latest
build with this Java Runtime Environment be placed on the ECuRep server.
Workarounds and Mitigations
IBM recommends that you review your entire environment to identify areas that
enable the SSLv3 protocol and take appropriate mitigation and remediation
actions.
Please see previous workarounds related to SSLv3 listed here Security
