"The version of FreeBSD installed on the remote host is prior to tested version. It is, therefore, affected by a
vulnerability as referenced in the a005aea9-47bb-11ee-8e38-002590c1f29c advisory.

  - ping reads raw IP packets from the network to process responses in         the pr_pack() function.  As
    part of processing a response ping has to         reconstruct the IP header, the ICMP header and if
    present a quoted         packet, which represents the packet that generated an ICMP error.         The
    quoted packet again has an IP header and an ICMP header. The pr_pack() copies received IP and ICMP headers
    into stack buffers         for further processing.  In so doing, it fails to take into account the
    possible presence of IP option headers following the IP header in either         the response or the
    quoted packet.  When IP options are present,         pr_pack() overflows the destination buffer by up to
    40 bytes. The memory safety bugs described above can be triggered by a remote         host, causing the
    ping program to crash. The ping process runs in a capability mode sandbox on all affected         versions
    of FreeBSD and is thus very constrained in how it can interact         with the rest of the system at the
    point where the bug can occur. (CVE-2022-23093)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version
number.");
