The remote version of INN is 
between 2.0 and 2.2.2

There is a known security flaw
in this version of INN which
may allow an attacker to execute
arbitrary code on this server
is the option 'verifycancels' is enabled
in inn.conf

Solution : upgrade to version 2.2.3 or make sure
that the option verifycancel is disabled on this
server.

Risk factor : High";

La version de INN est comprise entre 2.0
et 2.2.2.

Il y a un problème de sécurité dans la branche
2.x de INN qui peut permettre à un intrus
d'executer du code arbitraire sur ce système
pour peut que l'option 'verifycancels' soit activée
dans inn.conf

Solution : mettez le serveur à jour en 2.2.3 ou bien
assurez vous que l'option verifycancel n'est pas
activée dans inn.conf
