Description Tomas Hoger 2016-04-18 10:35:32 UTC 
It was discovered that the GCM (Galois/Counter Mode) implementation in the JCE component of OpenJDK used non-constant time comparison when comparing GCM authentication tag.  A remote attacker could possibly use this flaw to determine correct value of the authentication tag and bypass authentication protections of GCM.
