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.
* After the update or patch is applied, VMware Guest Tools must be updated in any pre-existing Windows 8.1 Guest Operating System followed by a reboot of the guest system.
** Workstation 9.x, Player 5.x and Fusion 5.x do not support Windows 8.1 Guest Operating Systems
