CVE-2016-1233 [HIGH] CVE-2016-1233 fuse: udev rule creates world-writeable /dev/cuse
CVE-2016-1233 fuse: udev rule creates world-writeable /dev/cuse
It was found that fuse package in Debian ships an udev rules adjusting permissions on the related /dev/cuse character device, making it world writable. This permits a local, unprivileged attacker to create an arbitrarily-named character device in /dev and modify the memory of any process that opens it and performs an ioctl on it. This in turn might allow a local, unprivileged attacker to escalate to root privileges.
