Language:

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 11.3.1 Big Sur. It is, therefore, affected by multiple vulnerabilities including the following:

 - An integer overflow was addressed with improved input validation (CVE-2021-30663).

 - A memory corruption issue was addressed with improved state management (CVE-2021-30666).

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 11.3.1 or later.
