DSA-143-1 krb5 -- Débordement d'entier

Date du rapport:

5 août 2002

Paquets concernés:

Vulnérabilité:

Oui

Références dans la base de données de sécurité:

Dans la base de données de suivi des bogues (chez SecurityFocus) : Identificateur BugTraq 5356.
Dans le dictionnaire CVE du Mitre : CVE-2002-0391.
Les annonces de vulnérabilité et les bulletins d'alerte du CERT : VU#192995.

Pour plus d'information:

Un bogue sur un débordement d'entier a été découvert dans la bibliothèque RPC qui est utilisée dans le système d'administration Kerberos 5 ; la bibliothèque RPC est une bibliothèque qui dérive de la bibliothèque SunRPC. Ce bogue peut être exploité pour obtenir un accès root sans autorisation sur l'hôte KDC. On pense que l'assaillant a besoin de s'authentifier sur le démon kadmin pour que cette attaque se réalise. Aucune exploitation n'est connue pour l'instant.

Ce problème a été corrigé dans la version 1.2.4-5woody1 pour l'actuelle distribution stable (Woody) et dans la version 1.2.5-2 pour la distribution unstable (Sid). Debian 2.2 (Potato) n'est pas affectée étant donné qu'elle ne contient pas de paquet krb5.

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

Corrigé dans:

Debian GNU/Linux 3.0 (woody)
