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 10.13.x prior to 10.13.6 Security Update 2020-005, 10.14.x prior to 10.14.6 Security Update 2020-005, or 10.15.x prior to 10.15.7. It is, therefore, affected by multiple vulnerabilities, as follows:

- Processing a maliciously crafted image may lead to arbitrary code execution. (CVE-2020-9961)

- A remote attacker may be able to unexpectedly alter application state. (CVE-2020-9941)

- Processing a maliciously crafted USD file may lead to unexpected application termination or arbitrary code execution. (CVE-2020-9973)

- A malicious application may be able to access restricted files. (CVE-2020-9968)

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 10.13.6 Security Update 2020-005 / 10.14.6 Security Update 2020-005 / 10.15.7 or later
