Security Bulletin: Vulnerabilities in IBM Java Runtime affect Watson Explorer, Watson Content Analytics, and OmniFind Enterprise Edition (CVE-2015-7575, CVE-2015-4872)
There are vulnerabilities in IBM® Runtime Environment Java™ Technology Edition that is used by Watson Explorer, Watson Content Analytics, and OmniFind Enterprise Edition.
DESCRIPTION: The TLS protocol could allow weaker than expected security caused by a collision attack when using the MD5 hash function for signing a ServerKeyExchange message during a TLS handshake. An attacker could exploit this vulnerability using man-in-the-middle techniques to impersonate a TLS server and obtain credentials. This vulnerability, commonly referred to as “SLOTH”, was disclosed as part of the IBM Java SDK updates in January 2016.

Workarounds and Mitigations
Users of Java 7 and later can address the issue by updating the /jre/lib/security/java.security file as follows (both steps are required):
- Add MD5 to the jdk.certpath.disabledAlgorithms property - e.g. jdk.certpath.disabledAlgorithms=MD2, RSA keySize < 1024, MD5
- Add MD5withRSA to the jdk.tls.disabledAlgorithms property - e.g. jdk.tls.disabledAlgorithms=SSLv3, RC4, DH keySize < 768, MD5withRSA
Java 6 requires code changes in the JSSE component in addition to the java.security file modifications, so upgrading the JDK is the only solution.
