macOS 11.x < 11.4 (HT212529)

high Nessus Plugin ID 149986
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.

Synopsis

The remote host is missing a macOS security update.

Description

The remote host is running a version of macOS / Mac OS X that is 11.x prior to 11.4 Big Sur. It is, therefore, affected by multiple vulnerabilities including the following:

- A remote attacker may be able to cause unexpected application termination or arbitrary code execution.
(CVE-2021-30712)

- A remote attacker may be able to cause unexpected application termination or arbitrary code execution.
(CVE-2021-30678)

- An application may be able to execute arbitrary code with kernel privileges. (CVE-2021-30704)

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

Solution

Upgrade to macOS 11.4 or later.
