Security Bulletin
Summary
There are multiple vulnerabilities in IBM Runtime Environment Java Technology
Edition. These vulnerabilities affect WebSphere DataPower XC10 versions 2.1
and 2.5. 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-2015-0138
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 cipher suite. 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://xforce.iss.net/xforce/xfdb/100691 for the
current score
CVSS Environmental Score*: Undefined
CVSS Vector: (AV:N/AC:M/Au:N/C:N/I:P/A:N)
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://xforce.iss.net/xforce/xfdb/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-2014-6593
DESCRIPTION: An unspecified vulnerability related to the JSSE component
has partial confidentiality impact, partial integrity impact, and no
availability impact.

Workarounds and Mitigations
The only mitigation is to apply the recommended fix. If you are using the
WebSphere eXtreme Scale Java client to communicate with the appliance, a
fix must be applied to the client as well, if that client is used to make
SSL connections to servers other than the appliance. Refer to CVE-2015-0138
in the latest WebSphere eXtreme Scale security bulletin for more information.
