"The version of hvloader / openssl installed on the remote CBL Mariner 2.0 host is prior to tested version. It is,
therefore, affected by a vulnerability as referenced in the CVE-2023-0466 advisory.

  - 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.

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