a. Windows-based VMware Tools Unsafe Library Loading vulnerability

   A vulnerability in the way VMware libraries are referenced allows    for arbitrary code execution in the context of the logged on user.
   This vulnerability is present only on Windows Guest Operating    Systems.

   In order for an attacker to exploit the vulnerability, the attacker    would need to lure the user that is logged on a Windows Guest    Operating System to click on the attacker's file on a network    share. This file could be in any file format. The attacker will    need to have the ability to host their malicious files on a    network share.

b. Windows-based VMware Tools Arbitrary Code Execution vulnerability

   A vulnerability in the way VMware executables are loaded allows for    arbitrary code execution in the context of the logged on user. This    vulnerability is present only on Windows Guest Operating Systems.

   In order for an attacker to exploit the vulnerability, the attacker    would need to be able to plant their malicious executable in a    certain location on the Virtual Machine of the user.  On most    recent versions of Windows (XP, Vista) the attacker would need to    have administrator privileges to plant the malicious executable in    the right location.

   Steps needed to remediate this vulnerability: See section 3.a.

   VMware would like to thank Mitja Kolsek of ACROS Security    (http://www.acrossecurity.com) for reporting this issue to us.

   The Common Vulnerabilities and Exposures project (cve.mitre.org)    has assigned the name CVE-2010-1142 to this issue.

   Refer to the previous table in section 3.a for what action    remediates the vulnerability (column 4) if a solution is    available. See above for remediation details.

c. Windows-based VMware Workstation and Player host privilege    escalation

   A vulnerability in the USB service allows for a privilege    escalation. A local attacker on the host of a Windows-based    Operating System where VMware Workstation or VMware Player    is installed could plant a malicious executable on the host and    elevate their privileges.

   In order for an attacker to exploit the vulnerability, the attacker    would need to be able to plant their malicious executable in a    certain location on the host machine.  On most recent versions of    Windows (XP, Vista) the attacker would need to have administrator    privileges to plant the malicious executable in the right location.

   VMware would like to thank Thierry Zoller for reporting this issue    to us.

   The Common Vulnerabilities and Exposures project (cve.mitre.org)    has assigned the name CVE-2010-1140 to this issue.

d. Third-party library update for libpng to version 1.2.37

   The libpng libraries through 1.2.35 contain an uninitialized-    memory-read bug that may have security implications.
   Specifically, 1-bit (2-color) interlaced images whose widths are    not divisible by 8 may result in several uninitialized bits at the    end of certain rows in certain interlace passes being returned to    the user. An application that failed to mask these out-of-bounds    pixels might display or process them, albeit presumably with benign    results in most cases.

   The Common Vulnerabilities and Exposures Project (cve.mitre.org)    has assigned the name CVE-2009-2042 to this issue.

e. VMware VMnc Codec heap overflow vulnerabilities

   The VMware movie decoder contains the VMnc media codec that is    required to play back movies recorded with VMware Workstation,    VMware Player and VMware ACE, in any compatible media player. The    movie decoder is installed as part of VMware Workstation, VMware    Player and VMware ACE, or can be downloaded as a stand alone    package.

   Vulnerabilities in the decoder allow for execution of arbitrary    code with the privileges of the user running an application    utilizing the vulnerable codec.

   For an attack to be successful the user must be tricked into    visiting a malicious web page or opening a malicious video file on    a system that has the vulnerable version of the VMnc codec installed.

   The Common Vulnerabilities and Exposures project (cve.mitre.org)    has assigned the names CVE-2009-1564 and CVE-2009-1565 to these    issues.

   VMware would like to thank iDefense, Sebastien Renaud of VUPEN    Vulnerability Research Team (http://www.vupen.com) and Alin Rad Pop    of Secunia Research for reporting these issues to us.

   To remediate the above issues either install the stand alone movie    decoder or update your product using the table below.

f. VMware Remote Console format string vulnerability

   VMware Remote Console (VMrc) contains a format string vulnerability.
   Exploitation of this issue may lead to arbitrary code execution on    the system where VMrc is installed.

   For an attack to be successful, an attacker would need to trick the    VMrc user into opening a malicious Web page or following a malicious    URL. Code execution would be at the privilege level of the user.

   VMrc is present on a system if the VMrc browser plug-in has been    installed. This plug-in is required when using the console feature in    WebAccess. Installation of the plug-in follows after visiting the    console tab in WebAccess and choosing 'Install plug-in'. The plug-    in can only be installed on Internet Explorer and Firefox.

   Under the following two conditions your version of VMrc is likely    to be affected :

   - the VMrc plug-in was obtained from vCenter 4.0 or from ESX 4.0      without patch ESX400-200911223-UG and
   - VMrc is installed on a Windows-based system

   The following steps allow you to determine if you have an affected    version of VMrc installed :

   - Locate the VMrc executable vmware-vmrc.exe on your Windows-based      system
   - Right click and go to Properties
   - Go to the tab 'Versions'
   - Click 'File Version' in the 'Item Name' window
   - If the 'Value' window shows 'e.x.p build-158248', the version of      VMrc is affected

   Remediation of this issue on Windows-based systems requires the    following steps (Linux-based systems are not affected) :

   - Uninstall affected versions of VMrc from the systems where the      VMrc plug-in has been installed (use the Windows Add/Remove      Programs interface)
   - Install vCenter 4.0 Update 1 or install the ESX 4.0 patch      ESX400-200911223-UG
   - Login into vCenter 4.0 Update 1 or ESX 4.0 with patch      ESX400-200911223-UG using WebAccess on the system where the VMrc      needs to be re-installed
   - Re-install VMrc by going to the console tab in WebAccess.  The      Console tab is selectable after selecting a virtual machine.

   Note: the VMrc plug-in for Firefox on Windows-based operating    systems is no longer compatible after the above remediation steps.
   Users are advised to use the Internet Explorer VMrc plug-in.

   VMware would like to thank Alexey Sintsov from Digital Security    Research Group for reporting this issue to us.

   The Common Vulnerabilities and Exposures project (cve.mitre.org)    has assigned the name CVE-2009-3732 to this issue.
