Debian Linux Security Advisory 2033-1 - It was discovered that in ejabberd, a distributed XMPP/Jabber server written in Erlang, a problem in ejabberd_c2s.erl allows remote authenticated users to cause a denial of service by sending a large number of c2s (client2server) messages; that triggers an overload of the queue, which in turn causes a crash of the ejabberd daemon.
