macOS 11.0.x < 11.0.1

high Nessus Plugin ID 143115


The remote host is missing a macOS security update


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.

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 11.0.1 or later
