Summary
fuse vulnerability
Details

It was discovered that FUSE is susceptible to a restriction bypass flaw on a system that has SELinux active. A local attacker with non-root privileges could mount a FUSE file system that is accessible to other users and trick them into accessing files on that file system, which could result in a Denial of Service or other unspecified conditions.
