macOS 10.14.x < 10.14.6 Security Update 2021-002 / 10.15.x < 10.15.7 Supplemental Update / macOS 11.x < 11.2.1 (HT212177)

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 10.14.x prior to 10.14.6 Security Update 2021-002 Mojave, 10.15.x prior to 10.15.7 Supplemental Update Catalina, or 11.x prior to 11.2.1 Big Sur. It is, therefore, affected by multiple vulnerabilities, including the following:

 - An out-of-bounds-write vulnerability caused by insufficient input validation that allows an application to execute arbitrary code with kernel privileges. (CVE-2021-1805)

 - A race condition due to insufficient validation that allows an application to execute arbitrary code with kernel privileges. (CVE-2021-1806)

 - A local privilege elevation vulnerability in sudo caused by a heap-based buffer overflow. (CVE-2021-3156)


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 10.14.6 Security Update 2021-002 / 10.15.7 Supplemental Update / macOS 11.2.1 or later.
