Oui

Références dans la base de données de sécurité :

Dans le dictionnaire CVE du Mitre : CVE-2009-0692, CVE-2009-1892.
Les annonces de vulnérabilité et les bulletins d'alerte du CERT : VU#410676.

Plus de précisions :

Plusieurs vulnérabilités distantes ont été découvertes dans l'implémentation DHCP d'ISC.

CVE-2009-0692
dhclient ne gère pas correctement les options de masques de sous-réseau trop longues, menant à un dépassement de pile et une possible exécution de code arbitraire.
CVE-2009-1892
Christoph Biedl a découvert que le serveur DHCP pourrait terminer en recevant certaines requêtes DHCP bien formées, à condition que la configuration du serveur mélange les définitions d'hôtes en utilisant « dhcp-client-identifier » et « hardware ethernet ». Cette vulnérabilité n'affecte que les versions de Lenny de dhcp3-server et dhcp3-server-ldap.

Pour l'ancienne distribution stable (Etch), ces problèmes ont été corrigés dans la version 3.0.4-13+etch2.

Pour la distribution stable (Lenny), ce problème a été corrigé dans la version 3.1.1-6+lenny2.

Pour la distribution unstable (Sid), ces problèmes seront corrigés prochainement.

Nous vous recommandons de mettre à jour vos paquets dhcp3.
