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. For the stable distribution (lenny), this problem has been fixed in version 2.0.1-6+lenny2. For the testing distribution (squeeze), this problem has been fixed in version 2.1.2-2. For the unstable distribution (sid), this problem has been fixed in version 2.1.2-2. We recommend that you upgrade your ejabberd packages.
