  "description": "If an X.509 certificate contains a malformed policy constraint andpolicy processing is enabled, then a write lock will be taken twicerecursively.  On some operating systems (most widely: Windows) thisresults in a denial of service when the affected process hangs.  Policyprocessing being enabled on a publicly facing server is not consideredto be a common setup.Policy processing is enabled by passing the \u0060-policy\u0027argument to the command line utilities or by calling the\u0060X509_VERIFY_PARAM_set1_policies()\u0027 function.Update (31 March 2023): The description of the policy processing enablementwas corrected based on CVE-2023-0466.",
