Is there a way to limit the maximum buffer size to be read from an ObjectInputStream in java?
I want to stop the deserialization if it becomes clear that the Object in question is crafted maliciously huge.
Of course, there is ObjectInputStream.read(byte[] buf, int off, int len), but I do not want to suffer the performance penalty of allocating, say byte[1000000].
Am I missing something here?
You write a
FilterInputStreamwhich will throw an exception if it discovers it has read more than a certain amount of data from its underlying stream.
