A buffer overflow issue was addressed with improved memory handling. This issue is fixed in Security Update 2021-008 Catalina, macOS Big Sur 11.6.2. Parsing a maliciously crafted audio file may lead to disclosure of user information.

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.

The remote host is running a version of macOS / Mac OS X that is 10.15.x prior to Catalina Security Update 2021-008 Catalina. It is, therefore, affected by multiple vulnerabilities :
