CVE-2015-3248

Estado: ModificadaMedia (4.7)—

openhpi/Makefile.am en OpenHPI en versiones anteriores a la 3.6.0 emplea permisos de escritura global para el directorio /var/lib/openhpi, lo que permite que los usuarios locales, cuando no se establecen correctamente las cuotas, llenen el hosting del sistema de archivos /var/lib y provoquen una denegación de servicio (consumo de disco).
