New in Version 5.5.6

Workstation 5.5.6 addresses the following security issues:

  • An internal security audit determined that a malicious user could attain and exploit LocalSystem privileges by causing the authd process to connect to a named pipe that is opened and controlled by the malicious user. In this situation, the malicious user could successfully impersonate authd and attain privileges under which Authd is executing.
    bug 221309, (Foundstone CODE-BUG-H-001)
  • This release updates the libpng library to version 1.2.22 to remove various security vulnerabilities.
    bug 224453
  • A vulnerability in VMware Workstation running on Windows allowed complete access to the host's file system from a guest machine. This access included the ability to create and modify executable files in sensitive locations.
    bug 224522, (CORE-2007-0930)
  • A security vulnerability in OpenSSL 0.9.7j could make it possible to forge a RSA key signature. Workstation 5.5.6 upgrades OpenSSL to version 0.9.7l to avoid this vulnerability.
    bug 236970), RSA Signature Forgery (CVE-2006-4339)
  • The authd process read and honored the vmx.fullpath variable in the user-writable file config.ini, creating a security vulnerability.
    bug 241646
  • The config.ini file could be modified by non-administrator to change the VMX launch path. This created a vulnerability that could be exploited to escalate a user's privileges.
    bug 241675

New in Version 5.5.5

Workstation 5.5.5 addresses the following security issues:

  • This release fixes a problem that prevented VMware Player from launching. This problem was accompanied by the error message VMware Player unrecoverable error: (player) Exception 0xc0000005 (access violation) has occurred. This problem could result in a security vulnerability from some images stored in virtual machines downloaded by the user.
  • This release fixes several security vulnerabilities in the VMware DHCP server that could enable a malicious web page to gain system-level privileges.
    Thanks to Neel Mehta and Ryan Smith of the IBM Internet Security Systems X-Force for discovering and researching these vulnerabilities.
    The Common Vulnerabilities and Exposures project (cve.mitre.org) assigned the following names to these issues: CVE-2007-0061, CVE-2007-0062, CVE-2007-0063.
  • This release fixes a security vulnerability that could allow a malicious remote user to exploit the library file IntraProcessLogging.dll to overwrite files in a system.
    Thanks to the Goodfellas Security Research Team for discovering and researching these vulnerabilities.
    The Common Vulnerabilities and Exposures project (cve.mitre.org) assigned the following name to this issue: CVE-2007-4059.
  • This release fixes a security vulnerability that could allow a malicious remote user to exploit the library file vielib.dll to overwrite files in a system.
    Thanks to the Goodfellas Security Research Team for discovering and researching these vulnerabilities.
    The Common Vulnerabilities and Exposures project (cve.mitre.org) assigned the following names to this issue: CVE-2007-4155.
  • This release fixes a security vulnerability that could allow a guest operating system user with administrative privileges to cause memory corruption in a host process, and thus potentially execute arbitrary code on the host. The Common Vulnerabilities and Exposures project (cve.mitre.org) assigned the following name to this issue: CVE-2007-4496.
    Thanks to Rafal Wojtczvk of McAfee for identifying and reporting this issue.
  • This release fixes a security vulnerability that could allow a guest operating system user without administrator privileges to cause a host process to become unresponsive or exit unexpectedly, making the guest operating system unusable. The Common Vulnerabilities and Exposures project (cve.mitre.org) assigned the following name to this issue: CVE-2007-4497.
    Thanks to Rafal Wojtczvk of McAfee for identifying and reporting this issue.
  • This release fixes a security vulnerability in which Workstation was starting registered Windows services such as the Authorization service with "bare" (unquoted) paths, such as c:\program files\vmware\.... Applications and services in Windows must be started with a quoted path. This vulnerability could allow a malicious user to escalate user privileges.
    Thanks to Foundstone for discovering this vulnerability.

In addition, Workstation 5.5.5 fixes the following problems:

  • This release fixes a problem that prevented template virtual machines stored in read-only directories from being opened.
  • This release fixes a problem that caused Workstation 5.5.x to incorrectly display Workstation 6.0 virtual machines as Current virtual machines for Workstation 5.5.x.
  • This issue can occur if the Microsoft XML Parser msxmlx.inf files have been corrupted by some activity on your host. For more information, see VMware Knowledge Base article 2038.

New in Version 5.5.4

Workstation 5.5.4 addresses the following security issues:

  • Virtual machines can be put in various states of suspension, as specified by the ACPI power management standard. When returning from a sleep state (S2) to the run state (S0), the virtual machine process (VMX) collects information about the last recorded running state for the virtual machine. Under some circumstances, VMX read state information from an incorrect memory location. This issue could be used to complete a successful Denial-of-Service attack where the virtual machine would need to be rebooted.
    Thanks to Tavis Ormandy of Google for identifying this issue.
    The Common Vulnerabilities and Exposures project (cve.mitre.org) assigned the name CVE- 2007-1337 to this issue.
  • Some VMware products support storing configuration information in VMware system files. Under some circumstances, a malicious user could instruct the virtual machine process (VMX) to store malformed data, causing an error. This error could enable a successful Denial-of-Service attack on guest operating systems.
    Thanks to Sungard Ixsecurity for identifying this issue.
    The Common Vulnerabilities and Exposures project (cve.mitre.org) assigned the name CVE-2007-1877 to this issue.
  • Some VMware products managed memory in a way that failed to gracefully handle some general protection faults (GPFs) in Windows guest operating systems. A malicious user could use this vulnerability to crash Windows virtual machines. While this vulnerability could allow an attacker to crash a virtual machine, we do not believe it was possible to escalate privileges or escape virtual containment.
    Thanks to Ruben Santamarta of Reversemode for identifying this issue.
    The Common Vulnerabilities and Exposures project (cve.mitre.org) assigned the name CVE-2007-1069 to this issue.
  • In a 64-bit Windows guest on a 64-bit host, debugging local programs could create system instability. Using a debugger to step into a syscall instruction may corrupt the virtual machine's register context. This corruption produces unpredictable results including corrupted stack pointers, kernel bugchecks, or vmware-vmx process failures.
    Thanks to Ken Johnson for identifying this issue.
    The Common Vulnerabilities and Exposures project (cve.mitre.org) assigned the name CVE-2007-1876 to this issue.
  • Shared Folders is a feature that enables users of guest operating systems to access a specified set of folders in the host's file system. A vulnerability exists that could allow an attacker to write arbitrary content from a guest system to arbitrary locations on the host system. In order to exploit this vulnerability, the VMware system must have at least one folder shared. Although the Shared Folder feature is enabled by default, no folders are shared by default, which means this vulnerability is not exploitable by default.
    Thanks to Greg MacManus of iDefense Labs for identifying this issue.
    The Common Vulnerabilities and Exposures project (cve.mitre.org) assigned the name CVE-2007-1744 to this issue.

In addition, Workstation 5.5.4 fixes the following problem:

  • A problem with VMware Tools caused the guest to run out of memory.

Experimental support for two-way Virtual Symmetric Multiprocessing (Virtual SMP) enables multiprocessor virtual machines.

For all supported configurations of 32-bit and 64-bit host and guest operating systems running on multiprocessor host machines, Workstation provides experimental support for two-way Virtual SMP. This enables you to assign two virtual processors to a virtual machine. You can assign two processors to the virtual machine only if the host machine has at least two logical processors. See Before You Begin.

VMware Player gives you greater flexibility in distributing virtual machines.

VMware Player is a free desktop application that lets you run a virtual machine on a Windows or Linux PC. VMware Player provides an intuitive user interface for running preconfigured virtual machines created with VMware Workstation, GSX Server, and ESX Server. On Windows hosts, the player also opens and plays Microsoft Virtual PC and Virtual Server virtual machines and Symantec LiveState Recovery system images. VMware Player makes your VMware virtual machines accessible to colleagues, partners, customers, and clients who do not own VMware products.

Note: Use of VMware Player is subject to the VMware Player End User License terms, and no support (including Support and Subscription) will be provided by VMware for VMware Player. For self-help resources, see the VMware Player FAQ at www.vmware.com/products/player/faqs.html. You may want to check the VMware Player Discussion Forum on the VMware VMTN Web site, at www.vmware.com/community/forum.jspa?forumID=123.

Workstation emulates a new Ethernet adapter type for 64-bit guests.

For Workstation virtual machines with supported 64-bit guest operating systems, Workstation 5.5 emulates a new Ethernet adapter type: the Intel PRO/1000 MT Adapter.

Workstation 5.5 driver certification updates

To maintain high quality and provide the best user experience, Workstation includes updated device drivers that are digitally signed. Workstation 5.5 completed and passed Microsoft's Designed for Windows XP 32-bit and 64-bit program.

Improved import capability lets you open and import Microsoft Virtual PC and Virtual Server virtual machines, as well as Symantec LiveState Recovery system images, directly into Workstation.

In Workstation 5.5, the VMware Virtual Machine Importer, formerly available only as a standalone utility, is incorporated into the Workstation program for Windows hosts. When you upgrade to Workstation version 5.5, you no longer need the standalone VMware Virtual Machine Importer application to convert Microsoft Virtual PC and Virtual Server virtual machines, as well as Symantec LiveState Recovery and Norton Ghost system images to a VMware virtual machine: you can open and convert virtual machines and system images directly from Workstation. You can import virtual machines and system images from the following versions of Microsoft Virtual PC, Virtual Server, Symantec LiveState Recovery, and Norton Ghost:

  • Microsoft Virtual PC, version 7 and later
  • Microsoft Virtual Server, all versions
  • Symantec LiveState Recovery Desktop, all versions
  • Symantec LiveState Recovery Standard Server, all versions
  • Symantec LiveState Recovery Advanced Server, all versions
  • Norton Ghost, version 9 and later

On Windows hosts, enhancements to the user interface let you customize Workstation toolbars to suit your workstyle.

On Windows hosts, you can now customize Workstation toolbars by adding and removing the power, view, and snapshot toolbars, and by adding, removing, and rearranging the buttons in those toolbars. The figure shows the Customize Toolbar window for the power toolbar.

image: Customize Toolbar window

Enhanced support for wireless Ethernet adapters used in bridged networking lets you connect your virtual machines to wireless networks on Linux hosts.

Workstation 5.5 adds support on Linux hosts for wireless Ethernet adapters used in bridged networking. Support for wireless Ethernet adapters is already present for Workstation on Windows hosts.

Enhanced autodetect makes it easier to configure devices for virtual machines.

Workstation extends existing autodetect support for CD-ROM drives to other hardware devices. You can now set a virtual machine to automatically detect the following hardware devices automatically:

  • CD-ROM drive
  • Floppy drive
  • Sound adapters
  • Parallel port
  • Serial port

Enhanced autoconnect automatically reconnects manually connected USB devices.

When you manually connect a USB device in Workstation 5.5, Workstation retains the virtual machine’s connection to the affected port on the host machine. You can then suspend or power off the virtual machine, or unplug the device. When you plug the device back in or resume the virtual machine, Workstation reconnects the device automatically.

Enhanced snapshot management makes it easier to work with snapshots.

In the snapshot manager, you can now select and delete multiple snapshots at once.

Enhanced command line interface helps you manage snapshots.

Workstation 5.5 enhances the command line interface (vmrun) so you can manage snapshots of virtual machines more easily. With simple vmrun commands, you can now quickly create, delete, list, and go to specific snapshots.

Memory page trimming can be disabled to improve performance.

To improve performance, you can now disable memory page trimming from the user interface, in VM > Settings > Options > Advanced.

Enhanced product update checking makes it more convenient to keep your Workstation software up to date.

Automatic checking for Workstation product updates has been enhanced. In Edit > Preferences, the Workspace tab now shows the time and result of the most recent automatic check for updates, and the time of the next scheduled check. The Workspace tab also now includes a Check now button, so you can check for product updates manually at any time from Edit > Preferences.

On Linux hosts, the user interface has been enhanced to work better with desktop appearance themes.

On Linux hosts, the Workstation user interface has been redesigned to better represent your chosen desktop appearance theme, and to work correctly with high- and low-contrast themes designed to increase accessibility for the visually impaired.

Workstation 5.5 extends the display resizing features Autofit Guest and Fit Guest Now to Linux guests.

The Autofit Guest feature changes the guest operating system display resolution to match the console window size. Fit Guest Now resizes the guest operating system's display so it fills as much of the screen as possible in quick switch mode. For the display resizing options to work, you must update VMware Tools to version 5.5 in the guest, and VMware Tools must be running. If you have virtual machines that were suspended under a version of VMware Tools before version 5.5, display resizing will not work until the virtual machines are completely powered off and then powered on again. (Rebooting the virtual is not sufficient.) Powering the suspended virtual machines off and on can be done before or after updating VMware Tools.
Caution: If you update VMware Tools without powering off and powering on suspended virtual machines, and then attempt to resize the guest, the display will be corrupted. All the restrictions on resizing that the X11 Windows system imposes on physical hosts still apply to guests.
Note:
The Autofit Guest and Fit Guest Now features are already supported for Windows guests.


Before You Begin

On Windows hosts, Workstation 5.5 requires more hard disk space for installation than previous versions of Workstation. On Windows hosts, a minimum of 250MB of free disk space is now required for basic installation.

Support for 64-bit guest operating systems

Workstation 5.5 supports virtual machines with 64-bit guest operating systems only on host machines that have one of the supported 64-bit processors:

  • AMD Athlon 64, revision D or later
  • AMD Opteron, revision E or later
  • AMD Turion 64, revision E or later
  • AMD Sempron, 64-bit-capable revision D or later (experimental support)
  • Intel EM64T VT-capable processors (experimental support)

When you power on a virtual machine with a 64-bit guest operating system, Workstation performs an internal check: if the host CPU is not a supported 64-bit processor, you cannot power on the virtual machine. VMware also provides a standalone utility that you can use without Workstation to perform the same check and determine whether your CPU is supported for Workstation virtual machines with 64-bit guest operating systems. You can download the 64-bit processor check utility from the VMware web site at www.vmware.com/download/

Note: In shopping for a processor that is compatible with Workstation 5.5 64-bit guests, you may be unable to determine the revision numbers of a given vendor's offering of AMD Athlon 64, Opteron, Turion 64, or Sempron processors. At this time, the only reliable way to determine whether any of these processors is a revision supported by Workstation 5.5, is by the manufacturing technology (CMOS): any of the AMD Athlon 64, Opteron, Turion 64, or Sempron processors whose manufacturing technology is 90nm SOI (.09 micron SOI) is compatible with Workstation 5.5 64-bit guests. Using this information, you should be able to determine — with your vendor, or from the AMD Web site ( http://www.amd.com/ ) — whether a particular AMD processor model is compatible with Workstation 5.5 64-bit guests.

Virtual machines with 64-bit operating systems are supported only for Workstation version 5.5. A virtual machine created in Workstation version 5.5 with a 64-bit operating system cannot be powered on or resumed in Workstation versions 5.0 and earlier. Also, virtual machines with 64-bit operating systems are not supported for VMware products other than Workstation 5.5.

If your host machine has a 32-bit processor or a 64-bit processor that is not supported, Workstation does not support 64-bit guest operating systems. If your host machine has a supported 64-bit processor, you can run supported 32-bit and 64-bit operating systems in either the host or a guest, in any combination.

Experimental support for two-way Virtual SMP

For all supported configurations of 32-bit and 64-bit host and guest operating systems running on multiprocessor host machines, Workstation 5.5 provides experimental support for two-way Virtual SMP. This includes any SMP hardware, including dual-core systems and hyperthreaded uniprocessor systems.

Guests with more than two virtual processors are not supported in Workstation 5.5. However, you can power on and run multiple two-way Virtual SMP virtual machines concurrently.

You can set the number of processors for the virtual machine in the virtual machine settings editor (VM > Settings), in the Hardware tab under Processors. The number of virtual processors is also displayed in the summary view of the virtual machine. You can also set the number of virtual processors when you create a virtual machine in the New Virtual Machine Wizard. This setting is available only if you choose to create a custom configuration; it does not appear in the typical configuration.

You can assign up to two virtual processors to a virtual machine, in both 32-bit and 64-bit guests. For this experimental feature, Workstation 5.5 allows you to power on and resume two-way Virtual SMP guests only on host machines with at least:

  • A single-processor or multiprocessor host with a dual-core CPU
  • A multiprocessor host with two or more CPUs
  • A single-processor or multiprocessor host with hyperthreading enabled
    Note: On hyperthreaded uniprocessor hosts, performance of virtual machines with virtual SMP may be subpar.

If the host does not have at least two logical processors, assigning two virtual processors is neither supported nor recommended: a warning message will appear. You can disregard this message and assign two virtual processors to the virtual machine, but, once you have finished creating the virtual machine, you will not be able to power it on unless you move it to a host machine with at least two logical processors.

You can use Workstation 5.5 or later, running on a multiprocessor host machine, to open a virtual machine, created in VMware ESX Server, that has one or more virtual processors. However, in Workstation you cannot power on or resume a virtual machine that has more than two virtual processors assigned, even if more processors were assigned when the virtual machine was created in ESX Server.

If you use Workstation to open a virtual machine that has more than two virtual processors assigned, the virtual machine’s summary view and the virtual machine settings editor (VM > Settings) will display the number of processors as Other (x), where x is the number of processors originally assigned in ESX Server. Workstation preserves this original configuration setting for the number of processors, even though two is the maximum number of processors supported. You must change this setting to two processors before you can power on the virtual machine in Workstation. Note that once you commit a change to this setting, by clicking OK in VM > Settings, the original setting for number of processors is discarded, and no longer appears as an option in VM > Settings.

Virtual machines with Virtual SMP are supported only for Workstation version 5.5. A virtual machine created in Workstation version 5.5 with two virtual processors cannot be powered on or resumed in Workstation versions 5.0 and earlier. Also, if you suspend an SMP guest in Workstation 5.5, you cannot resume the virtual machine in Workstation 5.0 and earlier versions.

Compatibility of programs in this release

The standalone VMware Virtual Machine Importer v1.0 is not compatible with Workstation 5.5. If you currently have the standalone VMware Virtual Machine Importer v1.0 (build 12997) installed, when you install Workstation 5.5, the Workstation installer requires you to manually uninstall Virtual Machine Importer v1.0. If you currently have Workstation 5.5 installed, do not attempt to install VMware Virtual Machine Importer v1.0. The version 1.0 importer cannot be installed over Workstation 5.5. Attempting this installation will damage the Workstation installation and disable the import capability built into Workstation 5.5.

The standalone VMware Virtual Machine Importer v1.5 is compatible with Workstation 5.5. You can install both programs on the same machine. The Windows control panel Add or Remove Programs will contain entries for VMware Virtual Machine Importer 1.5 and Workstation 5.5. The Virtual Machine Importer files will remain until you uninstall both the importer and Workstation applications.

Upgrade VMware Tools

Be sure to upgrade VMware Tools to the version included in this release. VMware Tools contains new drivers and performance enhancements to improve your entire Workstation experience.

Fixed Bugs

You can download a list of bugs reported in Workstation 5.5.4 (and earlier versions) that were fixed for the Workstation 5.5.5 release. (Download PDF)

Known Issues

The following are known issues with Workstation 5.5.x.

  • On Windows hosts, if you have configured and enabled a shared folder, it is possible for an attacker to write arbitrary content from a guest system to arbitrary locations on the host system. (bug 200360) http://bugzilla.vmware.com/show_bug.cgi?id=200360

The following are known issues with Workstation 5.5.3, Build 34685.

  • Workstation 5.5.3 does not support USB for Solaris guests.


  • Fit Guest to Window and Full Screen options corrupt display on Mandriva Linux 2006 guests running version 6.8.99 of the Xorg X Windows system.
    In virtual machines running Mandriva Linux 2006, with version 6.8.99 of the Xorg X Windows System, if you enable the option Fit Guest to Window, or if you switch to Full Screen mode, the display becomes corrupted. To work around this issue, upgrade to Xorg version 6.9. For more information, consult the documentation included with your distribution of Mandriva Linux 2006.


  • Workstation fails to install on 64-bit Linux hosts unless 32-bit compatibility libraries are installed in host.
    Some 64-bit Linux host operating systems don't install 32-bit compatibility libraries by default. Workstation runs on 64-bit systems, but needs the 32-bit compatibility libraries installed. When you try to install Workstation on a 64-bit Linux host without the 32-bit compatibility libraries, an error message similar to the following may appear:
    /usr/bin/ldd: line 171: /lib/ld-linux.so.2: No such file or directory

    To work around this problem, install a 32-bit compatibility package for your Linux distribution. The name of the 32-bit compatibility package varies across distributions. For example, for Ubuntu you should install the ia32-libs and ia32-libs-gtk packages. See your distribution's documentation or Web site to determine the 32-bit compatibility package for your distribution.


  • On Linux guests that have SELinux enabled, accessing shared folders (/mnt/hgfs) fails with kernel oops error messages.
    To work around this problem, disable SELinux in your guest. Refer to your guest operating system documentation for more information about SELinux and how to disable it. Once SELinux is disabled, you can access shared folders.


  • In guests running Red Hat Enterprise Linux 5.0 or Ubuntu Linux 6.10 (or any Linux guests that use Xorg X Windows system versions 7.1 or higher) the Workstation 5.5.x VMware Tools installer does not install drivers for X Windows, and consequently the mouse does not perform correctly.
    The Workstation 5.5.x VMware Tools installer does not yet recognize Xorg versions 7.1 and higher. Workstation-supported Linux distributions that use Xorg versions 7.1 and higher typically include working VMware video and mouse drivers. VMware Tools should automatically choose the included video driver, but you need to set the mouse driver manually:
    1. Install the vmmouse driver. Depending on the Linux distribution, the method for installing it varies, but the vmmouse driver package will have "vmmouse" in the name.
    2. Edit the ServerLayout section of the file /etc/X11/xorg.conf so that it includes the following entry:
      InputDevice "Mouse[0]" "CorePointer"
    3. The file /etc/X11/xorg.conf also includes an InputDevice section for the primary mouse. Edit this section as follows:
      Section "InputDevice"
         Identifier "Mouse[0]"
         Driver "vmmouse"
         Option "Device" "/dev/input/mice"
         Option "Name" "VMware Pointing Device"
      EndSection

    The mouse should now function properly.
