Workarounds and Mitigations
To address CVE-2015-7575, users that are on Java 7 or Java 8 can update the /jre/lib/security/java.security file as follows (both steps are required):
- Add MD5 to the jdk.certpath.disabledAlgorithms property - for example, jdk.certpath.disabledAlgorithms=MD2, RSA keySize < 1024, MD5
- Add MD5withRSA to the jdk.tls.disabledAlgorithms property - for example, jdk.tls.disabledAlgorithms=SSLv3, RC4, DH keySize < 768, MD5withRSA
