Jabber Studio jabberd SASL Negotiation Remote DoS

This script is Copyright (C) 2006-2013 Tenable Network Security, Inc.


Synopsis :

The remote instant messaging server is affected by a denial of service
issue.

Description :

The remote host is running jabberd, an open source messaging system
based on the Jabber protocol.

The version of jabberd installed on the remote host suffers a segfault
when a client sends a SASL 'response' stanza before a SASL 'auth'
stanza. An unauthenticated, remote attacker can leverage this flaw to
crash the application's c2s component, thereby denying service to
legitimate users.
