Virtuozzo 7 : readykernel-patch (VZA-2017-082)

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 vulnerabilities :

- An unprivileged user inside a container could cause a
denial of service (kernel crash in user_read()
function) using a specially crafted sequence of system
calls.

- The iscsi_if_rx function in
drivers/scsi/scsi_transport_iscsi.c in the Linux kernel
through 4.13.2 allows local users to cause a denial of
service (panic) by leveraging incorrect length
validation.

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.
