Bulletin d'alerte Debian
DSA-1963-1 unbound -- Erreur d'implémentation cryptographique
- Date du rapport :
- 23 décembre 2009
- Paquets concernés :
- unbound
- Vulnérabilité :
- Oui
- Références dans la base de données de sécurité :
- Dans le dictionnaire CVE du Mitre : CVE-2009-3602.
- Plus de précisions :
-
Unbound, un résolveur DNS, ne vérifie pas correctement les signatures cryptographiques sur les enregistrements NSEC3. Par conséquent, les zones signées avec la variante NSEC3 de DNSSEC perdent leur protection cryptographique (un attaquant devrait quand même mener une attaque d'empoisonnement de cache classique pour ajouter de mauvaises données dans le cache).
L'ancienne distribution stable (Etch) ne contient pas de paquet unbound.
Pour la distribution stable (Lenny), ce problème a été corrigé dans la version 1.0.2-1+lenny1.
Pour la distribution unstable (Sid) et la distribution testing (Squeeze), ce problème a été corrigé dans la version 1.3.4-1.
Nous vous recommandons de mettre à jour votre paquet unbound.
- Corrigé dans :
-
Debian GNU/Linux 5.0 (lenny)
