A logic issue existed resulting in memory corruption. This was addressed with improved state management. This issue is fixed in macOS Big Sur 11.0.1. An application may be able to execute arbitrary code with kernel privileges.

The remote host is running a version of macOS / Mac OS X that is 10.14.x prior to 10.14.6 Security Update 2021-001 Mojave, 10.15.x prior to 10.15.7 Security Update 2021-001 Catalina, or 11.x prior to 11.2. It is, therefore, affected by multiple vulnerabilities, including the following:

  - A logic issue existed resulting in memory corruption. This was addressed with improved state management.
    An application may be able to execute arbitrary code with kernel privileges. (CVE-2020-27904)

  - A logic issue existed that allowed applications to execute arbitrary code with kernel privileges.
    (CVE-2021-1750)

  - An out-of-bounds-write caused by improper input validation allowed maliciously crafted USD files to     unexpectedly terminate an application or cause arbitrary code execution. (CVE-2021-1762)

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

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)
