VMSA-2009-0005 : VMware Hosted products, VI Client and patches for ESX and ESXi resolve multiple security issues

This script is Copyright (C) 2009-2014 Tenable Network Security, Inc.


Synopsis :

The remote VMware ESXi / ESX host is missing one or more
security-related patches.

Description :

a. Denial of service guest to host vulnerability in a virtual device

A vulnerability in a guest virtual device driver, could allow a
guest operating system to crash the host and consequently any
virtual machines on that host.

VMware would like to thank Andrew Honig of the Department of
Defense for reporting this issue.

The Common Vulnerabilities and Exposures project (cve.mitre.org)
has assigned the name CVE-2008-4916 to this issue.

b. Windows-based host denial of service vulnerability in hcmon.sys

A vulnerability in an ioctl in hcmon.sys could be used to create
a denial of service on a Windows-based host. This issue can only
be exploited by a privileged Windows account.

VMware would like to thank Nikita Tarakanov for reporting this
issue to us.

The Common Vulnerabilities and Exposures project (cve.mitre.org)
has assigned the name CVE-2009-1146 to this issue.

Note: newly released hosted products (see table in this section)
address another potential denial of service in hcmon.sys as well.
Also this issue can only be exploited by a privileged Windows
account.

The Common Vulnerabilities and Exposures project (cve.mitre.org)
has assigned the name CVE-2008-3761 to this issue.

c. A VMCI privilege escalation on Windows-based hosts or Windows-
based guests.

The Virtual Machine Communication Interface (VMCI) is an
infrastructure that provides fast and efficient communication
between a virtual machine and the host operating system and
between two or more virtual machines on the same host.

A vulnerability in vmci.sys could allow privilege escalation on
Windows-based machines. This could occur on Windows-based hosts or
inside Windows-based guest operating systems.

Current versions of ESX do not support the VMCI interface and
hence they are not affected by this vulnerability.

Note: Installing the new hosted releases will not remediate the
issue on Windows-based guests. The VMware Tools packages will need
to be updated on each Windows-based guest followed by a reboot
of the guest system.

VMware would like to thank Nikita Tarakanov for reporting this
issue to us.

The Common Vulnerabilities and Exposures project (cve.mitre.org) has
assigned the name CVE-2009-1147 to this issue.

Refer to VMware KB article 1009826 on the steps that are needed to
remediate this vulnerability on Windows-based hosts. This KB article
is found at http://kb.vmware.com/kb/1009826.

d. VNnc Codec Heap Overflow vulnerabilities

The VNnc Codec assists in Record and Replay sessions. Record and
Replay record the dynamic virtual machine state over a period of
time.

Two heap overflow vulnerabilities could allow a remote attacker to
execute arbitrary code on VMware hosted products. For an attack to
be successful the user must be tricked into visiting a malicious web
page or opening a malicious video file.

VMware would like to thank Aaron Portnoy from TippingPoint DVLabs
for reporting these issues to us. TippingPoint has issued the
following identifiers: ZDI-CAN-435, ZDI-CAN-436.

The Common Vulnerabilities and Exposures project (cve.mitre.org) has
has assigned the names CVE-2009-0909 and CVE-2009-0910 to these
issues.

e. ACE shared folders vulnerability

The VMware Host Guest File System (HGFS) shared folders feature allows
users to transfer data between a guest operating system and the
non-virtualized host operating system that contains it.

A vulnerability in ACE shared folders could allow a previously disabled
and not removed shared folder in the guest to be enabled by a non ACE
Administrator.

VMware would like to thank Emmanouel Kellinis, KPMG London, penetration
testing team for reporting this issue to us.

The Common Vulnerabilities and Exposures project (cve.mitre.org) has
has assigned the name CVE-2009-0908 to this issue.

f. A remote denial of service vulnerability in authd for Windows
based hosts.

A vulnerability in vmware-authd.exe could cause a denial
of service condition on Windows hosts.

The Common Vulnerabilities and Exposures Project (cve.mitre.org)
has assigned the name CVE-2009-0177 to this issue.

g. VI Client Retains VirtualCenter Server Password in Memory

After logging in to VirtualCenter Server with VI Client, the
password for VirtualCenter Server might be present in the memory
of the VI Client.

Note: This vulnerability is present in VI Client and in order to
remediate the vulnerability, you will need to replace VI Client
with a fixed version (see below).

VMware would like to thank Craig Marshall for reporting this
issue to us.

The Common Vulnerabilities and Exposures Project (cve.mitre.org)
has assigned the name CVE-2009-0518 to this issue.
