Medium Nessus Plugin ID 111758

Synopsis

A virtualization application installed on the remote macOS or Mac OS X host is affected by a speculative execution side channel vulnerability.

Description

The version of VMware Fusion installed on the remote macOS or Mac OS X host is 10.x prior to 10.1.3. It is, therefore, vulnerable to a speculative execution side channel attack known as L1 Terminal Fault (L1TF). An attacker who successfully exploited L1TF may be able to read privileged data across trust boundaries.
