The version of FreeBSD installed on the remote host is prior to tested version. It is, therefore, affected by multiple vulnerabilities as referenced in the 9e2fdfc7-e237-4393-9fa5-2d50908c66b3 advisory.
Note that Nessus has not tested for these issues but has instead relied only on the application’s self-reported version number.

"The version of FreeBSD installed on the remote host is prior to tested version. It is, therefore, affected by multiple
vulnerabilities as referenced in the 9e2fdfc7-e237-4393-9fa5-2d50908c66b3 advisory.
- The X.Org project reports: When prepending values to an existing property an invalid offset
calculation causes the existing values to be appended at the wrong offset. The resulting
memcpy() would write into memory outside the heap-allocated array. This
vulnerability requires a legacy multi-screen setup with multiple protocol screens (Zaphod).
If the pointer is warped from one screen to the root window of the other screen,
the enter/leave code may retain a reference to the previous pointer window. Destroying this
window leaves that reference in place, other windows may then trigger a use-after-
free bug when they are destroyed. (CVE-2023-5367, CVE-2023-5380)
Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version
number.");
