[jira] [Created] (DIRAPI-485) Subtree refinement parser recurses without depth limit

Emmanuel Lécharny created DIRAPI-485:
----------------------------------------

             Summary: Subtree refinement parser recurses without depth limit 
                 Key: DIRAPI-485
                 URL: https://issues.apache.org/jira/browse/DIRAPI-485
             Project: Directory Client API
          Issue Type: Bug
    Affects Versions: 2.1.8
            Reporter: Emmanuel Lécharny
             Fix For: 2.1.9


A directory-management tool reads the _subtreeSpecification_ attribute of a _subentry_ from a compromised server.
The value is '_{ specificationFilter ' + 'not: '*20000 + 'item:person }_'; parsing overflows the stack and the tool's worker thread dies with _StackOverflowError_.
