摘要:
If an X.509 certificate contains a malformed policy constraint and policy processing is enabled, then a write lock will be taken twice recursively. On some operating systems (most widely: Windows) this results in a denial of service when the affected process hangs. Policy processing being enabled on a publicly facing server is not considered to be a common setup. Policy processing is enabled by passing the `-policy argument to the command line utilities or by calling either `X509_VERIFY_PARAM_add0_policy() or `X509_VERIFY_PARAM_set1_policies() functions.
