Description
VMware ESX, Workstation, and Fusion contain an out-of-bounds read vulnerability. A malicious actor with VM deployment privileges could trigger an out-of-bounds read, potentially leading to information disclosure or more likely a Denial-of-Service (DoS) condition of the host process. On Workstation and Fusion, the impact of this vulnerability is restricted to information disclosure.
