fuse vulnerability
==========================================================================
A security issue affects these releases of Ubuntu and its derivatives:
- Ubuntu 16.04 ESM
Summary:
FUSE is susceptible to a restriction bypass flaw.
Software Description:
- fuse: Filesystem in Userspace
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.
Update instructions:
The problem can be corrected by updating your system to the following
package versions:
Ubuntu 16.04 ESM:
fuse 2.9.4-1ubuntu3.1+esm1
libfuse2 2.9.4-1ubuntu3.1+esm1
In general, a standard system update will make all the necessary changes.
