"The remote host is running a version of macOS / Mac OS X that is 11.x prior to 11.6.2 Big Sur. It is, therefore,
affected by multiple vulnerabilities including the following:

  - A buffer overflow issue was addressed with improved memory handling. Processing a maliciously crafted USD 
    file may lead to unexpected application termination or arbitrary code execution. (CVE-2021-30979)

  - An out-of-bounds read was addressed with improved input validation. Playing a malicious audio file may 
    lead to arbitrary code execution. (CVE-2021-30958)

  - An out-of-bounds write issue was addressed with improved bounds checking. Processing a maliciously 
    crafted USD file may disclose memory contents. (CVE-2021-30929)

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