3. Problem Description

 a. VMware Workstation, Player and Fusion vmware-mount race condition

    The way temporary files are handled by the mounting process could
    result in a race condition. This issue could allow a local user on
    the host to elevate their privileges.

    VMware Workstation and Player running on Microsoft Windows are not
    affected.

    The Common Vulnerabilities and Exposures project (cve.mitre.org)
    has assigned the name CVE-2010-4295 to this issue.

    VMware would like to thank Dan Rosenberg for reporting this issue.

    The following table lists what action remediates the vulnerability
    (column 4) if a solution is available.

 b. VMware Workstation, Player and Fusion vmware-mount privilege
    escalation

    vmware-mount which is a suid binary has a flaw in the way libraries
    are loaded.  This issue could allow local users on the host to
    execute arbitrary shared object files with root privileges.

    VMware Workstation and Player running on Microsoft Windows are not
    affected.

    The Common Vulnerabilities and Exposures project (cve.mitre.org)
    has assigned the name CVE-2010-4296 to this issue.

    VMware would like to thank Martin Carpenter for reporting this
    issue.

    The following table lists what action remediates the vulnerability
    (column 4) if a solution is available.

    ESX            any       ESX      not affected


 c. OS Command Injection in VMware Tools update

    A vulnerability in the input validation of VMware Tools update
    allows for injection of commands. The issue could allow a  user
    on the host to execute commands on the guest operating system
    with root privileges.

    The issue can only be exploited if VMware Tools is not fully
    up-to-date.  Windows-based virtual machines are not affected.

    The Common Vulnerabilities and Exposures project (cve.mitre.org)
    has assigned the name CVE-2010-4297 to this issue.

    VMware would like to thank Nahuel Grisolia of Bonsai Information
    Security, http://www.bonsai-sec.com, for reporting this issue.

    Column 4 of the following table lists the action required to
    remediate the vulnerability in each release, if a solution is

  * hosted products are VMware Workstation, Player, ACE, Fusion.
  ** Non Windows-based guest systems on ESXi 3.5 and ESX 3.5 only:
     - Install the relevant ESX patch.
     - Manually upgrade tools in the virtual machine (virtual machine
       users will not be prompted to upgrade tools).  Note the VI
       Client may not show that the VMware tools is out of date in the
       summary tab.

 d. VMware VMnc Codec frame decompression remote code execution

    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.

    A function in the decoder frame decompression routine implicitly
    trusts a size value.  An attacker can utilize this to miscalculate
    a destination pointer, leading to the corruption of a heap buffer,
    and could 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 name CVE-2010-4294 to this issue.

    VMware would like to thank Aaron Portnoy and Logan Brown of
    TippingPoint DVLabs for reporting this issue.

    Column 4 of the following table lists the action required to
    remediate the vulnerability in each release, if a solution is
    available.
