CVE-2018-2663: Medium severity Oracle JDK vulnerability
It was discovered that the implementation of the ArrayBlockingQueue class in the Libraries component of OpenJDK did not check that all assumed invariants were satisfied after creating object instance from a serialized form, leaving the instance in an inconsistent state. If a Java application deserialized a specially-crafted input, this could cause it to raise an unexpected exceptions or allocate an excessive amount of memory.
