Description Tomas Hoger 2019-07-15 18:13:28 UTC 
It was discovered that the implementation of the Collections class in the Utilities component of OpenJDK did not limit the amount of memory allocated when creating object instance from a serialized form.  A specially-crafted input could cause a Java application to use an excessive amount of memory when deserialized.

Public now via Oracle CPU July 2019:
