FreeBSD : FreeBSD -- Lost mbuf flag resulting in data corruption (7a09a8df-ca41-11df-aade-0050568f000c)

This script is Copyright (C) 2010-2016 Tenable Network Security, Inc.


Synopsis :

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

Description :

The read-only flag is not correctly copied when a mbuf buffer
reference is duplicated. When the sendfile(2) system call is used to
transmit data over the loopback interface, this can result in the
backing pages for the transmitted file being modified, causing data
corruption.
