The remote ESXi is missing one or more security related Updates from VMSA-2010-0007. Summary VMware hosted products, vCenter Server and ESX patches resolve multiple security issues Relevant releases VMware Workstation 7.0, VMware Workstation 6.5.3 and earlier, VMware Player 3.0, VMware Player 2.5.3 and earlier, VMware ACE 2.6, VMware ACE 2.5.3 and earlier, VMware Server 2.0.2 and earlier, VMware Fusion 3.0, VMware Fusion 2.0.6 and earlier, VMware VIX API for Windows 1.6.x, VMware ESXi 4.0 before patch ESXi400-201002402-BG VMware ESXi 3.5 before patch ESXe350-200912401-T-BG VMware ESX 4.0 without patches ESX400-201002401-BG, ESX400-200911223-UG VMware ESX 3.5 without patch ESX350-200912401-BG VMware ESX 3.0.3 without patch ESX303-201002203-UG VMware ESX 2.5.5 without Upgrade Patch 15. Problem Description 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. 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. 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. 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. 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 g. Windows-based VMware authd remote denial of service A vulnerability in vmware-authd could cause a denial of service condition on Windows-based hosts. The denial of service is limited to a crash of authd. h. Potential information leak via hosted networking stack A vulnerability in the virtual networking stack of VMware hosted products could allow host information disclosure. A guest operating system could send memory from the host vmware-vmx process to the virtual network adapter and potentially to the host's physical Ethernet wire. i. Linux-based vmrun format string vulnerability A format string vulnerability in vmrun could allow arbitrary code execution. If a vmrun command is issued and processes are listed, code could be executed in the context of the user listing the processes. Solution Apply the missing patch(es).
