Descriptions

An unspecified udev rule in the Debian fuse package in jessie before 2.9.3-15+deb8u2, in stretch before 2.9.5-1, and in sid before 2.9.5-1 sets world-writable permissions for the /dev/cuse character device, which allows local users to gain privileges via a character device in /dev, related to an ioctl.

Una regla udev no especificada en el paquete fuse de Debian en jessie en versiones anteriores a 2.9.3-15+deb8u2, en stretch en versiones anteriores a 2.9.5-1 y en sid en versiones anteriores a 2.9.5-1 fija los permisos de escritura para todos para el dispositivo de carácter /dev/cuse, lo que podría permitir a usuarios locales obtener privilegios a través de un dispositivo de carácter in /dev, relacionado con un ioctl.

Jann Horn discovered a vulnerability in the fuse (Filesystem in Userspace) package in Debian. The fuse package ships an udev rules adjusting permissions on the related /dev/cuse character device, making it world writable.
