Virtuozzo 6 : parallels-server-bm-release / vzkernel / etc (VZA-2017-085)

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


Synopsis :

The remote Virtuozzo host is missing multiple security updates.

Description :

According to the versions of the parallels-server-bm-release /
vzkernel / etc packages installed, the Virtuozzo installation on the
remote host is affected by the following vulnerabilities :

- Kernel crash due to missing error handling for
negatively instantiated keys.

- A stack buffer overflow flaw was found in the way the
Bluetooth subsystem of the Linux kernel processed
pending L2CAP configuration responses from a client. On
systems with the stack protection feature enabled in
the kernel an unauthenticated attacker able to initiate
a connection to a system via Bluetooth could use this
flaw to crash the system. Due to the nature of the
stack protection feature, code execution cannot be
fully ruled out, although we believe it is unlikely.

- 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.
