Description Tomas Hoger 2018-04-14 20:43:19 UTC 
It was discovered that the implementation of the PriorityBlockingQueue class in the Concurrency 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.
