This issue was addressed by removing the vulnerable code. This issue is fixed in macOS Big Sur 11.0.1. An application may be able to gain elevated 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 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 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.
