  - 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. Policy
    processing is disabled by default but can be enabled by passing the `-policy' argument to the command line
    utilities or by calling the `X509_VERIFY_PARAM_set1_policies()' function. (CVE-2023-0464)
