New! Plugin Severity Now Using CVSS v3

The calculated severity for Plugins has been updated to use CVSS v3 by default. Plugins that do not have a CVSS v3 score will fall back to CVSS v2 for calculating severity. Severity display preferences can be toggled in the settings dropdown.


The remote host is missing a macOS security update.


The remote host is running a version of macOS / Mac OS X that is 10.14.x prior to 10.14.6 Security Update 2021-001 Mojave, 10.15.x prior to 10.15.7 Security Update 2021-001 Catalina, or 11.x prior to 11.2. It is, therefore, affected by multiple vulnerabilities, including the following:

- A logic issue existed resulting in memory corruption. This was addressed with improved state management.
An application may be able to execute arbitrary code with kernel privileges. (CVE-2020-27904)

- A logic issue existed that allowed applications to execute arbitrary code with kernel privileges.

- An out-of-bounds-write caused by improper input validation allowed maliciously crafted USD files to unexpectedly terminate an application or cause arbitrary code execution. (CVE-2021-1762)

Note that Nessus has not tested for this issue but has instead relied only on the operating system's self-reported version number.


Upgrade to macOS 10.14.6 Security Update 2021-001 / 10.15.7 Security Update 2021-001 / macOS 11.2 or later.
