S-195: Novell iPrint Client 'ienipp.ocx' ActiveX Vulnerability
Novell iPrint Client 'ienipp.oxc' ActiveX control is prone to a buffer-overflow vulnerability because the application fails to perform adequate boundary checks on user-supplied data. The risk is MEDIUM. Successfully exploiting this issue allows remote attackers to execute arbitrary code in the context of the application using the ActiveX control (typically Internet Explorer). Failed exploit attempts likely result in denial-of-service conditions.

NAME

       Net::SMTP::Server::Client - Client session handling for Net::SMTP::Server.

SYNOPSIS

	 use Carp;
	 use Net::SMTP::Server;
	 use Net::SMTP::Server::Client;
	 use Net::SMTP::Server::Relay;

	 $server = new Net::SMTP::Server('localhost', 25) ||
	   croak("Unable to handle client connection: $!
");

	 while($conn = $server->accept()) {
	   # We can perform all sorts of checks here for spammers, ACLs,
	   # and other useful stuff to check on a connection.

	   # Handle the client's connection and spawn off a new parser.
	   # This can/should be a fork() or a new thread,
	   # but for simplicity...
	   my $client = new Net::SMTP::Server::Client($conn) ||
	       croak("Unable to handle client connection: $!
");

	   # Process the client.  This command will block until
	   # the connecting client completes the SMTP transaction.
	   $client->process || next;

	   # In this simple server, we're just relaying everything
	   # to a server.  If a real server were implemented, you
	   # could save email to a file, or perform various other
	   # actions on it here.
	   my $relay = new Net::SMTP::Server::Relay($client->{FROM},
						    $client->{TO},
						    $client->{MSG});
	 }

DESCRIPTION

       The Net::SMTP::Server::Client module implements all the session handling required for a Net::SMTP::Server::Client connection.  The above
       example demonstrates how to use Net::SMTP::Server::Client with Net::SMTP::Server to handle SMTP connections.

       $client = new Net::SMTP::Server::Client($conn)

       Net::SMTP::Server::Client accepts one argument that must be a handle to a connection that will be used for communication.

       Once you have a new client session, simply call:

       $client->process

       This processes an SMTP transaction.  THIS MAY APPEAR TO HANG -- ESPECIALLY IF THERE IS A LARGE AMOUNT OF DATA BEING SENT.  Once this method
       returns, the server will have processed an entire SMTP transaction, and is ready to continue.

       Once $client->process returns, various fields have been filled in.  Those are:

	 $client->{TO}	  -- This is an array containing the intended
			     recipients for this message.  There may be
			     multiple recipients for any given message.

	 $client->{FROM}  -- This is the sender of the given message.
	 $client->{MSG}   -- The actual message data. :)
