    request: https://github.com/openssl/openssl/pull/13817 (rsa_pkcs1_implicit_rejection).
    These changes are part of OpenSSL 3.2 and have also been backported to stable
    versions of various Linux distributions, as well as to the PHP builds provided for
    Windows since the previous release. All distributors and builders should ensure that
    this version is used to prevent PHP from being vulnerable. (CVE-2024-2408)
