Virtuozzo 7 : readykernel-patch (VZA-2017-027)

This script is Copyright (C) 2017 Tenable Network Security, Inc.

Synopsis :

The remote Virtuozzo host is missing a security update.

Description :

According to the version of the vzkernel package and the
readykernel-patch installed, the Virtuozzo installation on the remote
host is affected by the following vulnerability :

- The packet_set_ring function in net/packet/af_packet.c
in the Linux kernel through 4.10.6 does not properly
validate certain block-size data, which allows local
users to cause a denial of service (overflow) or
possibly have unspecified other impact via crafted
system calls.

Note that Tenable Network Security has extracted the preceding
description block directly from the Virtuozzo security advisory.
Tenable has attempted to automatically clean and format it as much as
possible without introducing additional issues.
