a. VMware mount privilege escalation

VMware Workstation and Player contain a vulnerability in the handling of the vmware-mount command. A local malicious user may exploit this vulnerability to escalate their privileges to root on the host OS. The issue is present when Workstation or Player are installed on a Debian-based version of Linux.

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

A workaround for the issue is to remove the setuid bit from vmware-mount:

chmod u-s /usr/bin/vmware-mount

This workaround is relevant for both Workstation and Player.

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