"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 425b9538-ce5f-11ed-ade3-d4c9ef517024 advisory.

  - Applications that use a non-default option when verifying certificates may be vulnerable to an attack from
    a malicious CA to circumvent certain checks. Invalid certificate policies in leaf certificates are
    silently ignored by OpenSSL and other certificate policy checks are skipped for that certificate. A
    malicious CA could use this to deliberately assert invalid certificate policies in order to circumvent
    policy checking on the certificate altogether. Policy processing is disabled by default but can be enabled
    by passing the `-policy' argument to the command line utilities or by calling the
    `X509_VERIFY_PARAM_set1_policies()' function. (CVE-2023-0465)

  - The function X509_VERIFY_PARAM_add0_policy() is documented to implicitly enable the certificate policy
    check when doing certificate verification. However the implementation of the function does not enable the
    check which allows certificates with invalid or incorrect policies to pass the certificate verification.
    As suddenly enabling the policy check could break existing deployments it was decided to keep the existing
    behavior of the X509_VERIFY_PARAM_add0_policy() function. Instead the applications that require OpenSSL to
    perform certificate policy check need to use X509_VERIFY_PARAM_set1_policies() or explicitly enable the
    policy check by calling X509_VERIFY_PARAM_set_flags() with the X509_V_FLAG_POLICY_CHECK flag argument.
    Certificate policy checks are disabled by default in OpenSSL and are not commonly used by applications.
    (CVE-2023-0466)

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