** DISPUTADA ** BackBox Linux 4.6 permite a atacantes remotos provocar una denegación de servicio (consumo de CPU ksoftirqd) a través de una inundación de paquetes con direcciones IP de origen Martian (tal como se define en el RFC 1812 sección 5.3.7). Este producto habilita net.ipv4.conf.all.log_martians por defecto. NOTA: el proveedor reporta "Se ha demostrado que esta vulnerabilidad no tiene fundamento y es totalmente falsa y basada en suposiciones falsas".
