CVE-2011-4405

Estado: ModificadaAlta (7.5)—

Los scripts cupshelpers en system-config-printer en Ubuntu v11.04 y v11.10, como es usado por el servicio de descarga del controlador automático de impresión, usa una "conexión insegura" para peticiones de la base de datos OpenPrinting, lo que permite a atacantes remotos ejecutar código de su elección a través de un ataque 'man-in-the-middle (MITM)' que modifica paquetes o repositorios.
