10.14.x prior to 10.14.6 Security Update 2020-005, or 10.15.x prior to 10.15.7. It is, therefore, affected by multiple
vulnerabilities, as follows:

  - Processing a maliciously crafted image may lead to arbitrary code execution. (CVE-2020-9961)

  - A remote attacker may be able to unexpectedly alter application state. (CVE-2020-9941)

  - Processing a maliciously crafted USD file may lead to unexpected application termination or arbitrary
    code execution. (CVE-2020-9973)

  - A malicious application may be able to access restricted files. (CVE-2020-9968)

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