VMware Fusion 11.0.x < 11.5.6 Multiple Vulnerabilities (VMSA-2020-0023)

high Nessus Plugin ID 143117

Language:

Synopsis

A virtualization application installed on the remote macOS or Mac OS X host is affected by multiple vulnerabilities

Description

The version of VMware Fusion installed on the remote macOS or Mac OS X host is 11.0.x prior to 11.5.6. It is, therefore, affected by the following vulnerabilities:

 - A time-of-check time-of-use flaw exists related to ACPI device handling that allows an authenticated administrator to leak memory from the vmx process. (CVE-2020-3981)

 - A time-of-check time-of-use flaw exists related to ACPI device handling that allows an authenticated administrator to crash the vmx process or corrupt the hypervisor's memory heap.
 (CVE-2020-3982)

 - An unspecified flaw exists related to the VMCI host drivers that allows an attacker having access to the virtual machine to cause denial of service conditions via resource exhaustion.
 (CVE-2020-3995)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

Solution

Update to VMware Fusion version 11.5.6, 12.0, or later.
