----------------------------------------
Summary: Unbounded DSML filter nesting causes StackOverflowError
during parse
Key: DIRAPI-442
URL: https://issues.apache.org/jira/browse/DIRAPI-442
Project: Directory Client API
Issue Type: Bug
Affects Versions: 2.1.8
Reporter: Emmanuel Lécharny
Fix For: 2.1.9
An attacker sends a *DSML* batchRequest whose _searchRequest_ filter is
*100,000* nested *<not>* elements; during _Dsmlv2Parser.getNextRequest()_ the
recursive transform overflows the stack, the response is truncated, and
repeated requests degrade or wedge the gateway's thread pool.
