[Impact]
While the default configuration works fine for every package that uses the system libssl3, libssl1.1.1 (which implicitly loads the configuration on OPENSSL_crypto_init()) fails to parse it.
Our nodejs package vendors openssl 1.1.1, which means it will trigger this bug. In addition, upstream NodeJS explicitly points their statically-linked OpenSSL to this file as well, and ships 1.1.1 in their current LTS (branch 16.x).
Finally, we can also expect breakage for third-party packages that still depends on libssl1.1.
If the provider section isn't present in the configuration, libssl3 will load the default provider, which means that commenting out the section won't impact the behavior of standard libssl3 users.
[Test Plan]
On a system with a pristine openssl configuration:
$ sudo apt install nodejs
$ nodejs - <<EOF
var crypto = require('crypto')
const { privateKey, publicKey } = crypto.generateKeyPairSync('rsa', { modulusLength: 2048 });
var sign = crypto.createSign('RSA-SHA256');
sign.update(Buffer.from("hello"));
sign.sign(privateKey.export({type: 'pkcs1', format: 'pem'}));
EOF
Without the fix, the nodejs execution will have a non-zero return code and an uncaught exception with the following line:
Error: error:25066067:DSO support routines:dlfcn_load:could not load the shared library
With the fix, there shouldn't be any output, and an exit code of 0.
[Where problems could occur]
There could easily be user errors when trying to merge the new configuration, for instance if they enabled the legacy provider, as they might comment out the default provider loading section (which is necessary if any other provider is explicitly loaded).

Dear SRU team, please do not move this from -proposed to -updates before
the apt phasing fix has reached it first:

[Original report]
~ $ lsb-release -a
No LSB modules are available.
Distributor ID: Ubuntu
Description: Ubuntu 22.04 LTS
Release: 22.04
Codename: jammy
https://launchpad.net/debian/+source/openssl/3.0.3-7 includes a single change, https://sources.debian.org/src/openssl/3.0.3-8/debian/patches/Remove-the-provider-section.patch/
That patch solves a problem with programs that use OpenSSL v1 (statically or dynamically linked); these still read /etc/ssl/openssl.cnf, but the v3-specific sections in the sid/jammy default config may cause a failure.
One example: https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=1011051
Another example: a (non-Ubuntu) Node.js v16 (OpenSSL compiled statically) hits an error in its crypto lib:
~ $ node
Welcome to Node.js v16.15.0.
Type ".help" for more information.
> const { privateKey, publicKey } = crypto.generateKeyPairSync('rsa', { modulusLength: 2048 });
…
> var sign = crypto.createSign('RSA-SHA256')
…
> sign.update(Buffer.from("hello"))
…
> sign.sign(privateKey.export({type: 'pkcs1', format: 'pem'}))

Removing the relevant provider section lines (the Debian patch doesn't apply cleanly, hence the use of sed) fixes it:
~ $ sed -i '/_sect\b/s/^/# /' /etc/ssl/openssl.cnf
~ $ node

I realize there is no libssl1.1 on jammy, but a statically linked OpenSSL is not uncommon (Node.js being a very prominent example).
Would it be possible to get this Debian sid change ported to jammy?
