"Urgent VMware Patches Blunt Critical Hypervisor Flaws"

VMware's hypervisors have been found to have four significant flaws, with the most severe ones allowing a malicious actor with local administrative privileges on a virtual machine to execute code outside the guest. VMware has urged an emergency change to address these vulnerabilities, which affect its Workstation, Fusion, and ESXi hypervisors. The flaws were discovered by researchers at the Tianfu Cup Pwn Contest, and VMware has provided workarounds while acknowledging potential challenges in implementing them at scale.
