Une vulnérabilité du noyau Linux permet à un utilisateur local mal intentionné d'avoir accès à des informations confidentielles.
Description
Une vulnérabilité a été découverte dans le traitement des pointeurs vers les indices de décalage dans les fichiers (file offset) sur 64 bits.
Un utilisateur local mal intentionné peut exploiter cette vulnérabilité pour accèder à certaines parties de la mémoire du noyau. Il est possible d'y trouver certaines informations confidentielles (mots de passe par exemple).
