Description Tomas Hoger 2019-07-16 10:04:14 UTC 
A flaw was found in the way the JSSE component of OpenJDK handled certificate status / OCSP stapling message during TLS handshake.  A remote attacker could possibly use this flaw to gain access to certain sensitive information by manipulating TLS handshake messages.
