A memory corruption issue was addressed with improved input validation. This issue is fixed in macOS Big Sur 11.0.1, watchOS 7.1, iOS 12.4.9, watchOS 6.2.9, Security Update 2020-006 High Sierra, Security Update 2020-006 Mojave, iOS 14.2 and iPadOS 14.2, watchOS 5.3.9, macOS Catalina 10.15.7 Supplemental Update, macOS Catalina 10.15.7 Update. Processing a maliciously crafted font may lead to arbitrary code execution.

The version of Apple iOS running on the mobile device is prior to 12.4.9. It is, therefore, affected by multiple vulnerabilities, including the following:

  - A logic issue existed in the handling of Group FaceTime calls. The issue was addressed with improved state     management. This issue is fixed in iOS 12.4.9. A user may send video in Group FaceTime calls without knowing that     they have done so. (CVE-2020-27929)

  - A memory corruption issue was addressed with improved input validation. Processing a maliciously crafted font may     lead to arbitrary code execution. (CVE-2020-27930)

  - A malicious application may be able to execute arbitrary code with kernel privileges. (CVE-2020-27932)

  - A memory initialization issue was addressed. A malicious application may be able to disclose kernel memory.     (CVE-2020-27950)

The remote host is running a version of macOS / Mac OS X that is 10.13.x prior to 10.13.6 Security Update 2020-006 High Sierra, or 10.14.x prior to 10.14.6 Security Update 2020-006 Mojave. It is, therefore, affected by multiple vulnerabilities :

  - Processing a maliciously crafted font may lead to arbitrary code execution. (CVE-2020-27930)

  - A malicious application may be able to execute arbitrary code with kernel privileges. (CVE-2020-27932)

  - A malicious application may be able to disclose kernel memory. (CVE-2020-27950)

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)

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

The version of Apple iOS running on the mobile device is prior to 14.2. It is, therefore, affected by multiple vulnerabilities.
