Dans le dictionnaire CVE du Mitre : CVE-2007-2444, CVE-2007-2446, CVE-2007-2447.

Pour plus d'information:

Plusieurs problèmes ont été identifiés dans Samba, le serveur de fichier et d'impression SMB/CIFS pour GNU/Linux.

CVE-2007-2444
Lors de la traduction des SID depuis/vers les noms en utilisant la liste locale des comptes d'utilisateurs et des groupes, une erreur dans la pile interne de sécurité du démon smbd pouvait conduire à un passage au superutilisateur plutôt qu'à un compte d'utilisateur traditionnel. L'utilisateur était alors capable d'effectuer des opérations de protocole SMB/CIFS en tant que superutilisateur. Cette fenêtre d'opportunité pouvait permettre à l'attaquant de se doter de moyens supplémentaires d'accéder au serveur avec les droits du superutilisateur.
CVE-2007-2446
Divers bogues dans le traitement NDR par Samba pouvait permettre à un utilisateur d'envoyer des requêtes MS-RPC forgées afin d'écraser le tas (« heap ») avec ses propres données.
CVE-2007-2447
Des paramètres fournis par l'utilisateur étaient passés à /bin/sh sans être échappés, ce qui permettait l'exécution de commande arbitraire à distance.

Pour l'actuelle distribution stable (Etch), ces problèmes ont été corrigés dans la version 3.0.24-6etch1.

Pour les distributions de test (Lenny) et instable (Sid), ces problèmes ont été corrigés dans la version 3.0.25-1.

Nous vous recommandons de mettre à jour vos paquets samba.

Corrigé dans:

Debian GNU/Linux 4.0 (etch)
