Virtualizor 2.8.1 Launched (Stable Branch)

Hi,

The Virtualizor Team has released Virtualizor 2.8.1
This version fixes some bugs and adds some new features.
The following is a list of changes in this version :

1) [Feature] We have launched a new WHMCS module which is major re-write of the existing module. This module brings the Virtualizor Interface into WHMCS. The new module also changes the way a Product / Service is created for Virtualizor in WHMCS. Now the Admin will need to define a plan in the Virtualizor Master and then select the same in WHMCS. The existing plans created on “WHMCS Module 1” will be backward compatible. The new module guide is as follows :
http://virtualizor.com/wiki/WHMCS_Module_V2

The following is a screenshot of the Client area in the new module :

OpenVZ Vulnerability Requires Kernel Update

An update for OpenVZ was just released to address a serious security vulnerability and it is recommended that you update as soon as possible.
Note : This bug is not a part of the Virtualizor VPS Panel, but rather a bug in OpenVZ.

A flaw was found in the way the Linux kernel handled GS segment register base switching when recovering from an #SS (stack segment) fault on an erroneous return to user space. A local, unprivileged Container user could use this flaw to crash the Hardware Node or escalate their privileges on the system. Hence we recommend that all nodes running OpenVZ should update immediately.

The changelog of the latest kernel :
https://wiki.openvz.org/Download/kernel/rhel6/042stab094.8

To update please run the following command :
root> yum update

A system reboot will be required for the changes to take place. Before rebooting please make sure the kernel entry in your grub is the latest OpenVZ kernel.

If you need any assistance you can contact the Virtualizor team.

Xen Vulnerability XSA-108


An update for Xen has been released to address a vulnerability where a buggy or malicious HVM guest can crash the host or read data relating to other guests or the hypervisor itself. Xen Versions 4.1 and above are affected.

Note : This bug is not a part of the Virtualizor VPS Panel, but rather a bug in Xen. The entire detail of the bug can be found below.

If your Virtualizor Host Node is running CentOS 6 with Xen (mostly it will be running Xen 4.2.x) or Xen 4.1 and above, you will need to yum update Xen and reboot the server. The command is as follows :

root> yum -u update
root> /usr/bin/grub-bootxen.sh

Note : You will need to reboot the server.

If you need any assistance updating Xen, please contact the Virtualizor support team.

Following is the security advisory :

Xen Security Advisory CVE-2014-7188 / XSA-108
                   version 4

              Improper MSR range used for x2APIC emulation

UPDATES IN VERSION 4
====================

Public release.

ISSUE DESCRIPTION
=================

The MSR range specified for APIC use in the x2APIC access model spans
256 MSRs. Hypervisor code emulating read and write accesses to these
MSRs erroneously covered 1024 MSRs. While the write emulation path is
written such that accesses to the extra MSRs would not have any bad
effect (they end up being no-ops), the read path would (attempt to)
access memory beyond the single page set up for APIC emulation.

IMPACT
======

A buggy or malicious HVM guest can crash the host or read data
relating to other guests or the hypervisor itself.

VULNERABLE SYSTEMS
==================

Xen 4.1 and onward are vulnerable.

Only x86 systems are vulnerable.  ARM systems are not vulnerable.

MITIGATION
==========

Running only PV guests will avoid this vulnerability.

CREDITS
=======

This issue was discovered Jan Beulich at SUSE.

RESOLUTION
==========

Applying the attached patch resolves this issue.

xsa108.patch        xen-unstable, Xen 4.4.x, Xen 4.3.x, Xen 4.2.x
