CVE-2014-4263: Medium severity ORACLE Jrockit vulnerability
The Diffie-Hellman (DH) key exchange algorithm implementation in the OpenJDK Security component failed to validate public Diffie-Hellman parameters properly. This could allow OpenJDK implementation to accept and use weak parameters, making it possible for attackers to recover the negotiated key.
