Description Tomas Hoger 2014-07-14 21:10:41 UTC
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.
