Description Tomas Hoger 2020-04-14 20:22:40 UTC 
A flaw was found in the way the TLS implementation in the JSSE component of OpenJDK handled unexpected Certificate messages during the TLS handshake.  This could possibly allow an attacker to tamper with certificate verification performed during the handshake.
