 c. Windows-based VMware Workstation and Player host privilege

    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 (
    has assigned the name CVE-2010-1140 to this issue.
