Une vulnérabilité a été découverte dans OpenBSD qui permet à un utilisateur mal intentionné d'effectuer un déni de service sur la machine vulnérable.
Description
Une vulnérabilité a été découverte dans la mise en œuvre du traitement
des paquets ICMP par OpenBSD configuré en mode bridge et gérant le
