    Wouter Coekaerts discovered that ejabberd, a distributed XMPP/Jabber server
    written in Erlang, is vulnerable to the so-called "billion laughs" attack
    because it does not prevent entity expansion on received data.
    This allows an attacker to perform denial of service attacks against the
    service by sending specially crafted XML data to it.
