Emmanuel Lecharny updated DIRSERVER-1260:
-----------------------------------------
One idea would be to limit the incoming PDU size to a certain size. If it
exceeds this size, then the connection is closed, and the PDU is discarded.
This size will be configurable, and be a part of the server.xml file.
> Add a protection agains DoS attacks

> Key: DIRSERVER-1260
> URL: https://issues.apache.org/jira/browse/DIRSERVER-1260
> Project: Directory ApacheDS
> Issue Type: New Feature
> Affects Versions: 1.5.4
> Reporter: Emmanuel Lecharny
> Fix For: 1.5.5
>
>
> A malicious user can send hand crafted PDUs which can break the server in OOM
> errors. Another kind of attack would be to send big images, leading to OOM
> too.
> We must implement some protection against such DoS attacks (which may not be
> malicious).
