Workarounds and Mitigations

For CVE-2015-7575:

Users of Java 7 and later can address the issue by updating the /jre/lib/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 file modifications, so upgrading the JDK is the only solution.
