VMware Workstation and Fusion contain an integer overflow vulnerability in VMware NAT service when IPv6 mode is enabled. This issue may lead to an out-of-bound read which can then be used to execute code on the host in conjunction with other issues. Note: IPv6 mode for VMNAT is not enabled by default.
The product performs a calculation that can produce an integer overflow or wraparound when the logic assumes that the resulting value will always be larger than the original value. This occurs when an integer value is incremented to a value that is too large to store in the associated representation. When this occurs, the value may become a very small or negative number.
