"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 a28e8b7e-fc70-11ec-856e-d4c9ef517024 advisory.

  - AES OCB mode for 32-bit x86 platforms using the AES-NI assembly optimised implementation will not encrypt
    the entirety of the data under some circumstances. This could reveal sixteen bytes of data that was
    preexisting in the memory that wasn't written. In the special case of in place encryption, sixteen bytes
    of the plaintext would be revealed. Since OpenSSL does not support OCB based cipher suites for TLS and
    DTLS, they are both unaffected. Fixed in OpenSSL 3.0.5 (Affected 3.0.0-3.0.4). Fixed in OpenSSL 1.1.1q
    (Affected 1.1.1-1.1.1p). (CVE-2022-2097)

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