Workarounds and Mitigations
For CVE-2015-7575:
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.
