  3. Problem Description

    a. Guest privilege escalation in VMware Tools

    A kernel NULL dereference vulnerability was found in VMware
    Tools running on Microsoft Windows 8.1. Successful exploitation
    of this issue could lead to an escalation of privilege in the
    guest operating system.

    VMware would like to thank Tavis Ormandy from the Google Security
    Team for reporting this issue to us.

    The vulnerability does not allow for privilege escalation from
    the Guest Operating System to the host. This means that host
    memory can not be manipulated from the Guest Operating System.

    The Common Vulnerabilities and Exposures project (cve.mitre.org)
    has assigned the name CVE-2014-3793 to this issue.

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