FreeBSD : FreeBSD -- Incorrect privilege validation in the NFS server (e5d2442d-5e76-11e6-a6c3-14dae9d210b8)

This script is Copyright (C) 2016 Tenable Network Security, Inc.

Synopsis :

The remote FreeBSD host is missing one or more security-related

Description :

Problem Description :

The kernel incorrectly uses client supplied credentials instead of the
one configured in exports(5) when filling out the anonymous credential
for a NFS export, when -network or -host restrictions are used at the
same time.

Impact :

The remote client may supply privileged credentials (e.g. the root
user) when accessing a file under the NFS share, which will bypass the
normal access checks.

Solution :

Update the affected packages.

Risk factor :

Medium / CVSS Base Score : 6.4
