DSA-183-1 krb5 -- Dépassement de tampon

Date du rapport:

29 octobre 2002

Paquets concernés:

Vulnérabilité:

Oui

Références dans la base de données de sécurité:

Dans le dictionnaire CVE du Mitre : CVE-2002-1235.
Les annonces de vulnérabilité et les bulletins d'alerte du CERT : CA-2002-29, VU#875073.

Pour plus d'information:

Tom Yu et Sam Hartman du MIT ont découvert un nouveau débordement de pile dans la fonction kadm_ser_wrap_in du serveur d'administration de Kerberos v4. Il existe un code fonctionnel d'exploitation circulant sur Internet de ce bogue de kadmind, ce qui le rend d'autant plus sérieux. L'implémentation du MIT, krb5, fournit une compatibilité avec la version 4, la bibliothèque complète de la v4, le support du serveur de krb4 et une fonctionnalité cliente limitée de v4.

Ce problème a été corrigé dans la version 1.2.4-5woody3 pour l'actuelle distribution stable (Woody) et dans la version 1.2.6-2 pour la distribution instable (Sid). L'ancienne distribution stable (Potato) n'est pas affectée étant donné que les paquets krb5 ne sont pas inclus dedans.

Nous recommandons la mise à jour de vos paquets krb5 immédiatement.

Corrigé dans:

Debian GNU/Linux 3.0 (woody)
