DSA-273-1 krb4 -- Faille cryptographique

Date du rapport:

28 mars 2003

Paquets concernés:

Vulnérabilité:

Oui

Références dans la base de données de sécurité:

Dans le dictionnaire CVE du Mitre : CVE-2003-0138, CVE-2003-0139.
Les annonces de vulnérabilité et les bulletins d'alerte du CERT : VU#623217, VU#442569.

Pour plus d'information:

Une faiblesse cryptographique dans la version 4 du protocole Kerberos permet à un attaquant d'utiliser une attaque via un texte simple pour être authentifié par les contrôleurs de domaine. D'autres faiblesses cryptographiques dans l'implémentation krb4 incluse dans la distribution de krb5 du MIT permettent l'utilisation d'attaques copier/coller pour fabriquer des tickets krb4 pour des clients non autorisés si les clés triple-DES sont utilisées pour les services de clé de krb4. Ces attaques peuvent compromettre l'entière infrastructure d'authentification Kerberos.

Pour la distribution stable (Woody), ce problème a été corrigé dans la version 1.1-8-2.3.

Pour l'ancienne distribution stable (Potato), ce problème a été corrigé dans la version 1.0-2.3.

Pour la distribution instable (Sid), ce problème a été corrigé dans la version 1.2.2-1.

Nous vous recommandons de mettre à jour vos paquets krb4 immédiatement.

Corrigé dans:

Debian GNU/Linux 2.2 (potato)
