Debian DSA-2033-1 : ejabberd - heap overflow

medium Nessus Plugin ID 45546



The remote Debian host is missing a security-related update.


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.


Upgrade the ejabberd packages.

For the stable distribution (lenny), this problem has been fixed in version 2.0.1-6+lenny2.
