Bug description:
OpenSSL 3.2.0 introduced a change on PKCS#1 v1.5 RSA to return random

There are available backports already:
* 3.0 https://gitlab.com/redhat/centos-
stream/rpms/openssl/-/blob/c9s/0120-RSA-PKCS15-implicit-
rejection.patch?ref_type=heads
* 1.1.1 https://gitlab.com/redhat/centos-
stream/rpms/openssl/-/blob/c8s/openssl-1.1.1-pkcs1-implicit-
rejection.patch?ref_type=heads
This change is needed to fix CVE-2023-50782.
