A vulnerability has been reported in VMware Workstation, Player, Fusion, ESX, and ESXi, which can be exploited by malicious, local users to bypass certain security restrictions.

The vulnerability is caused due to an error within the VMware Tools, which can be exploited by a user on the host system to execute arbitrary commands with root privileges on a guest system by injecting commands when updating VMware Tools via the VMware Server Infrastructure Web Access.

Successful exploitation requires that the VMware Tools are not completely up-to-date.

Note: This does not affect Windows-based virtual machines.
