A fully compromised ESXi host can force VMware Tools to fail to
authenticate host-to-guest operations, impacting the confidentiality and
integrity of the guest virtual machine.

Notes

Author	Note
mdeslaur	per upstream, this is a low-severity issue an attacker must have root access on the host to exploit the guest, which doesn’t really give any extra privileges
