Vulnerability from certfr_avis - Published: - Updated:

Plusieurs vulnérabilités affectant MIT Kerberos 5 permettent à une personne d'exécuter du code arbitraire à distance.

Description

Trois vulnérabilités ont été identifiées dans le démon d'administration kadmind de MIT Kerberos 5. La première concerne un débordement de mémoire (CVE-2007-2798), les deux autres sont des erreurs au niveau de la librairie RPC (CVE-2007-2442 et CVE-2007-2443). Ces vulnérabilités peuvent être exploitées par un attaquant pour exécuter du code arbitraire à distance.

Ces vulnérabilités ne concernent pas le protocole Kerberos.
