Ruby 2.5 is currently in security maintenance mode (see https://www.ruby-lang.org/en/downloads/branches/), and these do not appear to be security fixes.  While the choice of whether to backport the changes is up to @usa, I would be surprised if they were merged into Ruby 2.5.

Bug #17175: Ruby 2.5: OpenSSL related test failures
https://bugs.ruby-lang.org/issues/17175#change-87916

* Author: jaruga (Jun Aruga)
* Status: Open
* Priority: Normal
* Backport: 2.5: REQUIRED, 2.6: UNKNOWN, 2.7: UNKNOWN
----------------------------------------
I am facing OpenSSL test failures when building the Ruby 2.5 latest version 2.5.8 + some patches with OpenSSL 1.1.1g on Fedora 34 and 33.
AS this issue does not happen for Ruby 2.6, Ruby 2.7, and does not happen on Ruby 2.5.8 on Fedora 32.

I am assuming the following change in Fedora 33 affects this issue.

https://fedoraproject.org/wiki/Changes/StrongCryptoSettings2
> We update the current system-wide crypto policy to further disable legacy cryptographic protocols (TLS 1.0 and TLS 1.1), weak Diffie-Hellman key exchange sizes (1024 bit), and use of the SHA-1 hash in signatures. 

Do we need to apply the following kind of patch to Ruby's testing pem files?
