Title: DSA-2248-1 ejabberd -- denial of service
Description: 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.

Title: DSA-2033-1 ejabberd -- heap overflow
Description: 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 messages; that triggers an overload of the queue, which in turn causes a crash of the ejabberd daemon. For the stable distribution, this problem has been fixed in version 2.0.1-6+lenny2. For the testing distribution, this problem has been fixed in version 2.1.2-2. For the testing distribution, this problem has been fixed in version 2.1.2-2. We recommend that you upgrade your ejabberd packages.
