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. A vulnerability in RC4 stream cipher affects IBM WebSphere Application Server and Progress Software DataDirect Connect ODBC drivers that are shipped as components of IBM InfoSphere Information Server. Information about this Bar Mitzvah security vulnerability has been published in a WebSphere Application Server security bulletin. Information about this vulnerability and Progress Software DataDirect Connect ODBC drivers is below. 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) 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. CVSS Base Score: 4 CVSS Temporal Score: See http://xforce.iss.net/xforce/xfdb/100153 for the current score CVSS Environmental Score*: Undefined CVSS Vector: (AV:N/AC:H/Au:N/C:P/I:P/A:N) CVEID: CVE-2015-0383 DESCRIPTION: An unspecified vulnerability in Oracle Java SE and JRockit related to the Hotspot component has no confidentiality impact, partial integrity impact, and complete availability impact. This issue is only applicable on HP and Solaris platforms. CVSS Base Score: 5.4 CVSS Temporal Score: See http://xforce.iss.net/xforce/xfdb/100148 for the current score CVSS Environmental Score*: Undefined CVSS Vector: (AV:L/AC:M/Au:N/C:N/I:P/A:C) CVEID: CVE-2015-2808 DESCRIPTION: The RC4 algorithm, as used in the TLS protocol and SSL protocol, could allow a remote attacker to obtain sensitive information. An attacker could exploit this vulnerability to remotely expose account credentials without requiring an active man-in-the-middle session. Successful exploitation could allow an attacker to retrieve credit card data or other sensitive information. This vulnerability is commonly referred to as "Bar Mitzvah Attack".

For IBM InfoSphere Information Server version 8.0, IBM recommends upgrading to a fixed, supported version of the product. You should verify that applying this fix does not cause any compatibility issues. The fix disables RC4 stream cipher by default. If you change this setting you will expose yourself to the attack described above. IBM recommends that you review your entire environment to identify other areas where you have enabled the RC4 stream cipher and take appropriate mitigation and remediation actions. Additionally, perform the remediation step for the DataDirect Connect ODBC drivers per information in the "Workarounds and Mitigations" section. Workarounds and Mitigations For all InfoSphere Information Server releases, disable RC4 stream cipher usage in the Progress Software DataDirect Connect ODBC drivers.
