Subject: [PATCH] Add a Certificate Policies Test
Test that a valid certificate policy is accepted and that an invalid
certificate policy is rejected. Specifically we are checking that a
leaf certificate with an invalid policy is detected.

Subject: [PATCH] Ensure that EXFLAG_INVALID_POLICY is checked even in leaf
certs
Even though we check the leaf cert to confirm it is valid, we
later ignored the invalid flag and did not notice that the leaf
cert was bad.

Subject: [PATCH] test: add test cases for the policy resource overuse
These trees have pathological properties with respect to building. The small
tree stays within the imposed limit, the large tree doesn't.
The large tree would consume over 150Gb of RAM to process.

Subject: [PATCH] x509: excessive resource use verifying policy constraints
A security vulnerability has been identified in all supported versions
of OpenSSL related to the verification of X.509 certificate chains
that include policy constraints. Attackers may be able to exploit this
vulnerability by creating a malicious certificate chain that triggers
exponential use of computational resources, leading to a denial-of-service
(DoS) attack on affected systems.
Fixes CVE-2023-0464
