Vulnerability from certfr_avis

Une vulnérabilité dans le serveur DHCPv6 de l'ISC permet à un utilisateur malveillant de provoquer un déni de service à distance.

Description

Le serveur DHCPv6 ne traite pas de manière correcte les messages relatifs à des adresses rejetées ou marquées comme abandonnées. L'arrêt inopiné du serveur qui en résulte permet à un utilisateur malveillant de provoquer un déni de service à distance.

Le serveur DHCPv4 n'est pas concerné par cette vulnérabilité.

Solution

Les versions 4.1.2-P1, 4.1-ESV-R1 et 4.2.1b1 de DHCPv6 corrigent ce problème.

Se référer au bulletin de sécurité de l'éditeur pour l'obtention des correctifs (cf. section Documentation).
