CVE-2016-4924

Estado: ModificadaMedia (5.5)—

Una vulnerabilidad de permisos incorrectos en Juniper Networks Junos OS en vMX podría permitir que usuarios locales sin privilegios en un sistema host tengan acceso de lectura a imágenes vMX o vPFE y obtengan información sensible contenida en ellas como claves criptográficas privadas. Se encontró el problema durante un análisis de seguridad interno del producto. Juniper SIRT no conoce ninguna explotación maliciosa de esta vulnerabilidad. No hay ningún otro producto o plataforma de Juniper Networks que se vea afectado por este problema. Las distribuciones afectadas son: Juniper Networks Junos OS 15.1 anteriores a 15.1F5 y 14.1 anteriores a 14.1R8.
