    Package        : ejabberd
    Vulnerability  : heap overflow
    Problem type   : remote
    Debian-specific: no
    CVE Id         : CVE-2010-0305
    Debian Bug     : 568383
    
    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 testing distribution (sid), this problem has been fixed in
    version 2.1.2-2.
    
    
    We recommend that you upgrade your ejabberd packages.
