Plus de précisions :

L'équipe MIT Kerberos Development a découvert un certain nombre de failles de sécurité dans le logiciel MIT Kerberos Version 5. Le projet Common Vulnerabilities and Exposures identifie les failles de sécurité suivantes :

  • CAN-2004-0642 [VU#795632]

    Une erreur de double libération peut permettre à des attaquants distants non authentifiés d'exécuter n'importe quel code sur le KDC (centre de distribution de clés Kerberos) ou les clients.

  • CAN-2004-0643 [VU#866472]

    Plusieurs erreurs de double libération peut permettre à des attaquants authentifiés d'exécuter n'importe quel code sur les serveurs applicatifs Kerberos.

  • CAN-2004-0644 [VU#550464]

    Une faille de sécurité exploitable à distance causant un déni de service a été trouvée dans le KDC et ses bibliothèques.

  • CAN-2004-0772 [VU#350792]

    Plusieurs erreurs de double libération peut permettre à des attaquants distants d'exécuter n'importe quel code sur le serveur. Ceci n'affecte pas la version dans Woody.

Pour la distribution stable (Woody), ces problèmes ont été corrigés dans la version 1.2.4-5woody6.

Pour la distribution instable (Sid), ces problèmes ont été corrigés dans la version 1.3.4-3.

Nous vous recommandons de mettre à jour vos paquets krb5.

Corrigé dans :

Debian GNU/Linux 3.0 (woody)
