Ubuntu 16.04 ESM : FUSE vulnerability (USN-5326-1)

high Nessus Plugin ID 158939

Language:

Synopsis

The remote Ubuntu host is missing a security update.

Description

The remote Ubuntu 16.04 ESM host has packages installed that are affected by a vulnerability as referenced in the USN-5326-1 advisory.

 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.

Tenable has extracted the preceding description block directly from the Ubuntu security advisory.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Update the affected fuse, libfuse-dev and / or libfuse2 packages.
