ASA-2019-00563 – VMware Workstation and VMware Fusion: Denial-of-service vulnerability due to improper handling of certain IPv6 packets

VMware Workstation and Fusion contain a network denial-of-service vulnerability due to improper handling of certain IPv6 packets. An attacker may exploit this issue by sending a specially crafted IPv6 packet from a guest machine on the VMware NAT to disallow network access for all guest machines using VMware NAT mode. This issue can be exploited only if IPv6 mode for VMNAT is enabled.
