Background

open-vm-tools contains tools for VMware guests.

Description

A pipe accessible to unprivileged users in the VMWare guest does not sufficiently sanitize input.

Impact

An unprivileged guest user could achieve root privileges within the guest.

Workaround

There is no known workaround at this time.

Resolution

All open-vm-tools users should upgrade to the latest version:

 # emerge --sync
 # emerge --ask --oneshot --verbose ">=app-emulation/open-vm-tools-12.1.0"
