macOS 11.0.x < 11.0.1

high Nessus Plugin ID 143115
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 11.0.x prior to 11.0.1. It is, therefore, affected by multiple vulnerabilities, including the following:

- An out-of-bounds write issue that can lead to unexpected application termination or arbitrary code execution when opening a maliciously crafted PDF file. (CVE-2020-9876)

- An out-of-bounds write caused by insufficient input validation that can lead to arbitrary code execution when processing a maliciously crafted image. (CVE-2020-9883)

- A remote attacker may be able to unexpectedly alter the Mail application date due to insufficient checks.
(CVE-2020-9941)

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 11.0.1 or later
