Security Bulletin


SSLv3 contains a vulnerability that has been referred to as the Padding Oracle On Downgraded Legacy Encryption (POODLE) attack. SSLv3 is enabled in IBM® SDK, Java Technology Edition.

Vulnerability Details

CVE-ID: CVE-2014-3566

DESCRIPTION: Product could allow a remote attacker to obtain sensitive information, caused by a design error when using the SSLv3 protocol. A remote user with the ability to conduct a man-in-the-middle attack could exploit this vulnerability via a POODLE (Padding Oracle On Downgraded Legacy Encryption) attack to decrypt SSL sessions and access the plaintext of encrypted connections.

CVSS Base Score: 4.3
CVSS Temporal Score: See for the current score
CVSS Environmental Score*: Undefined
CVSS Vector: (AV:N/AC:M/Au:N/C:P/I:N/A:N)

Affected Products and Versions

AIX 5.3, 6.1 and 7.1.
VIOS 2.2.x

The following fileset levels (VRMF) are vulnerable, if the respective Java version is installed:
For Java7 Release 1: Equal to or less than
For Java7: Equal to or less than
For Java6: Equal to or less than
For Java5: Equal to or less than

Note: To find out whether the affected filesets are installed on your systems, refer to the lslpp command found in AIX user's guide.

Example: lslpp -L | grep -i java

Workarounds and Mitigations

IBM SDK, Java Technology Edition, Version 7: Please refer to the following link:

IBM SDK, Java Technology Edition, Version 6: Please refer to the following link:

IBM SDK, Java Technology Edition, Version 5:

Currently, the only solution for IBM SDK, Java Technology Edition, Version 5 is to make programmatic change to an application designed to run on the IBM 5.0 JRE (Java Runtime Environment). For example:

If using

Set the https.protocols system property explicitly to disallow SSLv3 (the default value for this property allows SSLv3). For example use the following command line option:


If using or

Programmatically set the enabled protocol for the socket(s) to "TLSv1" using an appropriate API. The best solution depends on the application. For example:

SSLContext.getInstance()          e.g. SSLContext.getInstance("TLSv1")
SSLEngine.setEnabledProtocols()   e.g. engine.setEnabledProtocols(new String[] {"TLSv1"});
SSLSocket.setEnabledProtocols()   e.g. socket.setEnabledProtocols(new String[] {"TLSv1"});
SSLServerSocket.setEnabledProtocols()  e.g. serverSocket.setEnabledProtocols(new String[] {"TLSv1"});

IBM recommends that you review your entire environment to identify areas that enable the SSLv3 protocol and take appropriate mitigation and remediation actions. The most immediate mitigation action that can be taken is disabling SSLv3. You should verify disabling SSLv3 does not cause any compatibility issues.
