Description Tomas Hoger 2013-02-04 07:24:28 UTC 
It was discovered that JSSE component in OpenJDK did not properly validate Diffie-Hellman public keys.  A malicious SSL/TLS client could use this flaw to perform a small subgroup attack on the Diffie-Hellman protocol, resulting in weak session key to be negotiated for the connection, or possibly disclose portions of the server's Diffie-Hellman private key.
