CVE-2011-3191

Estado: ModificadaAlta (8.8)—

Error de signo de entero en la función CIFSFindNext en fs/cifs/cifssmb.c en el kernel de Linux antes de v3.1 permite a los servidores CIFS remotos provocar una denegación de servicio (corrupción de memoria) o posiblemente tener un impacto no especificado a través de un valor de gran longitud en una respuesta a una petición de lectura de un directorio.
