An out-of-bounds read was addressed with improved input validation. This issue is fixed in tvOS 14.3, macOS Big Sur 11.1, Security Update 2020-001 Catalina, Security Update 2020-007 Mojave, iOS 14.3 and iPadOS 14.3, iCloud for Windows 12.0, watchOS 7.2. Processing a maliciously crafted image may lead to arbitrary code execution.

According to its banner, the version of Apple TV on the remote device is prior to 14.3. It is, therefore, affected by multiple vulnerabilities as described in the HT212005 advisory:

  - An out-of-bounds write issue within CoreAudio processing may allow a maliciously crafted audio file to cause     arbitrary code execution. (CVE-2020-27948)

  - A memory corruption issue within FontParser processing may allow a maliciously crafted font file to cause     arbitrary code execution. (CVE-2020-27943, CVE-2020-27944, CVE-2020-29624)

  - An out-of-bounds read isue within ImageIO processing may allow maliciously crafted image to cause arbitrary     code execution. (CVE-2020-29618)     Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

The remote host is running a version of macOS / Mac OS X that is 10.14.x prior to 10.14.6 Security Update 2020-007 Mojave, 10.15.x prior to 10.15.7 Security Update 2020-001 Catalina, or 11.x prior to 11.1. It is, therefore, affected by multiple vulnerabilities, including the following:

  - Processing a maliciously crafted audio file may lead to arbitrary code execution. (CVE-2020-9960,     CVE-2020-10017, CVE-2020-27908, CVE-2020-27910, CVE-2020-27916, CVE-2020-27948)

  - Processing a maliciously crafted image may lead to arbitrary code execution. (CVE-2020-9962,     CVE-2020-27912, CVE-2020-27919, CVE-2020-27923, CVE-2020-27924, CVE-2020-29611, CVE-2020-29616,     CVE-2020-29618)

  - Processing a maliciously crafted font file may lead to arbitrary code execution. (CVE-2020-9956,     CVE-2020-27922, CVE-2020-27931, CVE-2020-27943, CVE-2020-27944, CVE-2020-27952)

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 14.3. It is, therefore, affected by multiple vulnerabilities.
