Doc Type: Bug Fix
Doc Text:
It was discovered that the SSL/TLS implementation in the JSSE component in OpenJDK failed to properly check whether the ChangeCipherSpec was received during the SSL/TLS connection handshake. An MITM attacker could possibly use this flaw to force a connection to be established without encryption being enabled.

Description Tomas Hoger 2015-01-16 14:52:53 UTC 
It was discovered that the SSL/TLS implementation in the JSSE component in OpenJDK failed to properly check if the ChangeCipherSpec was received during SSL/TLS connection handshake.  A man-in-the-middle attacker could possibly use this flaw to force connection to be established without encryption being enabled.
