For unsupported versions of the product IBM recommends upgrading to a fixed,
supported version/release/platform of the product.

The planned maintenance release dates for WebSphere Message Broker and IBM
Integration Bus are available at :

http://www.ibm.com/support/docview.wss?uid=swg27006308

Note:

As a result of the SLOTH vulnerability the cryptographic hash algorithm

MD5

is no longer considered secure. Installing any of the above fixes or altering
the below configuration will disable all uses of the MD5 algorithm through
Java. Any certificate that is signed with MD5 and any cipher suite used
during TLS handshaking which tries to use MD5withRSA is not accepted.

A further IBM Integration Bus and WebSphere Message Broker bulletin which
covers SLOTH is available here:

http://www-01.ibm.com/support/docview.wss?uid=swg21975233

Workarounds and Mitigations

For CVE-2015-7575:

Users of Java 7 and later can address the issue by updating the java.security
file to disable the use of the MD5 algorithm.

1. Edit the java.security file in the jre/lib/security directory of the IBM
Integration Bus or WebSphere Message Broker installation.

For example:

v10:

c:\Program Files\IBM\IIB\10.0.0.2\common\jdk\jre\lib\security\java.security

/opt/ibm/iib/10.0.0.2/common/jdk/jre/lib/security/java.security (LinuxX64
only)

/opt/ibm/iib/10.0.0.2/common/jre/lib/security/java.security

v9 & v8 with APAR IT03599 applied :

c:\Program Files\IBM\MQSI\9.0.0.4\jre17\lib\security\java.security

/opt/ibm/mqsi/9.0.0.4/jre17/lib/security/java.security

c:\Program Files\IBM\MQSI\8.0.0.6\jre17\lib\security\java.security

/opt/ibm/mqsi/8.0.0.6/jre17/lib/security/java.security

2. Add MD5 to the jdk.certpath.disabledAlgorithms property

For example:

jdk.certpath.disabledAlgorithms=MD2, RSA keySize < 1024,

MD5

3. Add MD5withRSA to the jdk.tls.disabledAlgorithms property

For example:

jdk.tls.disabledAlgorithms=SSLv3, RC4, DH keySize < 768,

MD5withRSA


For users of Java 6 the only solution is to upgrade the JRE by installing the
APAR IT13380.
