Hi Kumar,

The other limits on the number of references (maxref) and size of the stream (maxbytes) cover the similar potential cases. The maxarray limit is targeted at limiting the size of arrays, different considerations apply to other data structures.

Thanks, Roger

Hi All,

I'm mailing here for the first time and I am unaware of any rules for

question

JEP 290  <https://openjdk.java.net/jeps/290>solves the problem of
deserialization vulnerabilities except some collection classes which
includes TreeMap and LinkedList.

Can we have any solution or any work around to counter that?

In our RMI interface we are accepting Objects which may have TreeMap and
since there's no check on the size of treemap it is vulnerable to DDos
Attack. We have solution for ArrayList, Hashmap etc, Can we have something
similar for TreeMap and LinkedList as well?


Regards,

Kumar Gaurav
