Threat Analysis

VMware ESXi and Workstation contain a time-of-check time-of-use (TOCTOU) race condition vulnerability that leads to an out-of-bounds write. Successful exploitation enables an attacker with local administrative privileges on a virtual machine to execute code as the virtual machine's VMX process running on the host.

Remediation Directive
