Bertrand Delacretaz resolved SLING-5288.
----------------------------------------
Resolution: Won't Fix
Marking won't fix as my IO-487 contribution has been accepted in Apache
Commons, we can then use that.
> Restrict which classes can be deserialized

> Key: SLING-5288
> URL: https://issues.apache.org/jira/browse/SLING-5288
> Project: Sling
> Issue Type: Bug
> Components: General
> Reporter: Bertrand Delacretaz
> Assignee: Bertrand Delacretaz
>
> To avoid a recently reported Java deserialization vulnerability [1], we
> should restrict which classes are accepted when deserializing binaries.
> I have created a prototype SafeObjectInputStream at [2], which refuses to
> operate on classes that are outside a whitelist.
> We probably also need a wrapper for ObjectInputStreams provided by the
> environment, that looks a bit harder to create, for now we can already
> discuss this prototype to see if we want to pursue the idea.
