CVE-2022-3996

A vulnerability was found in OpenSSL. This security flaw occurs 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 issue results in a denial of service when the affected process hangs. Policy processing enabled on a publicly-facing server is not considered a standard setup. Policy processing is enabled by passing the -policy' argument to the command line utilities or by calling either the X509_VERIFY_PARAM_add0_policy()’ or `X509_VERIFY_PARAM_set1_policies()’ functions.
