  "description": "Applications that use a non-default option when verifying certificates maybevulnerable to an attack from a malicious CA to circumvent certain checks.Invalid certificate policies in leaf certificates are silently ignored byOpenSSL and other certificate policy checks are skipped for thatcertificate.A malicious CA could use this to deliberately assert invalid certificatepoliciesin order to circumvent policy checking on the certificate altogether.Policy processing is disabled by default but can be enabled by passingthe \u0060-policy\u0027 argument to the command line utilities or by calling the\u0060X509_VERIFY_PARAM_set1_policies()\u0027 function.",
