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 is commonly referred to as
"SLOTH".

Workarounds and Mitigations
The new JREs that are supplied by the above fixes resolve the CVE-2015-7575
(SLOTH) vulnerability.
Note that CSS 5.1 uses Java 6 and has issued a patch.
CSS 5.2.0 and CSS 5.2.1 use Java 8 and are not issuing a patch at this time
because the vulnerability can be eliminated as follows:
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
Note: If you install a Java fix pack, that will overwrite the above
java.security file changes.
