Description
Snort est un logiciel libre de détection d'intrusion.
Une vulnérabilité dans le pré-processeur Back Orifice de Snort permet à
un utilisateur mal intentionné, au moyen d'un paquet habilement
construit, d'exécuter du code arbitraire à distance sur la machine
vulnérable.
Contournement provisoire
Désactiver le pré-processeur Back Orifice. Pour cela, commenter la ligne
preprocessor bo dans le fichier de configuration Snort snort.conf.
Redémarrer Snort afin de prendre en compte les modifications.
Solution

Snort est téléchargeable à l'adresse suivante :
