CVE-2016-1233
CVE-2016-1233 describes a privilege-escalation in the Debian fuse package: an unspecified udev rule makes the /dev/cuse device world-writable, enabling a local unprivileged user to create or interact with devices via ioctl and potentially modify memory of processes opening the device. Affected ar...
Debian DSA-3451-1 : fuse - security update
Jann Horn discovered a vulnerability in the fuse Filesystem in Userspace package in Debian. The fuse package ships an udev rule adjusting permissions on the related /dev/cuse character device, making it world writable. This permits a local, unprivileged attacker to create an arbitrarily-named...
