The remote host is running a version of macOS / Mac OS X that is 11.x prior to 11.3 Big Sur. It is, therefore, affected by multiple vulnerabilities including the following:
A memory corruption issue which could allow an application restricted memory read access (CVE-2021-1808).
A memory corruption issue which could allow an application to cause unexpected system termination or to write kernel memory (CVE-2021-1828).
An out-of-bounds wirte issue which could allow a malicious application to execute arbitrary code with kernel privileges (CVE-2021-1834).
Note that Nessus has not tested for this issue but has instead relied only on the operating system’s self-reported version number.
