The remote host is running a version of macOS / Mac OS X that is 11.x prior to 11.6 Big Sur. It is, therefore, affected by multiple vulnerabilities including the following:
A use after free issue was addressed with improved memory management. Exploitation of this vulnerability may lead to arbitrary code execution. (CVE-2021-30858)
An integer overflow was addressed with improved input validation. Exploitation of this vulnerability may lead to arbitrary code execution. (CVE-2021-30860)
Insufficient checks when processing maliciously crafted dfont files may lead to arbitrary code execution. (CVE-2021-30841, CVE-2021-30842, CVE-2021-30843)
Note that Nessus has not tested for this issue but has instead relied only on the operating system’s self-reported version number.
