Descriptions

The logging functionality in dhcpd in ISC DHCP before 4.2.3-P2, when using Dynamic DNS (DDNS) and issuing IPv6 addresses, does not properly handle the DHCPv6 lease structure, which allows remote attackers to cause a denial of service (NULL pointer dereference and daemon crash) via crafted packets related to a lease-status update.

La funcionalidad de registro en el dhcpd de ISC DHCP anterior a v4.2.3-P2, cuando se utiliza DNS dinámico (DDNS) y direcciones IPv6, no maneja correctamente la estructura de arrendamiento (lease structure) DHCPv6, permitiendo a atacantes remotos provocar una denegación de servicio (puntero a NULL y el caída del servicio) mediante paquetes especialmente elaborados en relación con una actualización lease-status.
