The verification of the Stable Release Update for openssl has completed
successfully and the package is now being released to -updates.
Subsequently, the Ubuntu Stable Release Updates Team is being
unsubscribed and will not receive messages about this bug report. In
the event that you encounter a regression using the package from
-updates please report a new bug using ubuntu-bug and tag the bug report
regression-update so we can easily find any regressions.

Bug description:
=== SRU information ===
[Meta]
This bug is part of a series of three bugs for a single SRU.
The "central" bug with the global information and debdiff is http://pad.lv/2033422
[Impact]
Openssl using an engine dumps core upon certificate creation; other operations are probably affected too. Overall, engines are likely mostly unusable.
[Test plan]
- An openssl engine is req. to test the fix.
- A z13 / LinuxONE LPAR or z/VM guest is needed, with attached APQN.
- Check with 'lszcrypt -V' the availability (online) of the hw crypto resources.
- Install the needed package that allows to exploit the hw crypto resources:
sudo apt-get install libica-utils libica? openssl-ibmca
- And copy a working sample openssf.cnf file:
sudo cp /usr/share/doc/openssl-ibmca/examples/openssl.cnf.sample /etc/ssl/openssl.cnf
- Verify if the 'openssl engine' lists an ibmca engine,
in addition to the dynamic engine:
openssl engine
(dynamic) Dynamic engine loading support
(ibmca) Ibmca hardware engine support <===
- try to create a new certificate, using this cmd-line:
openssl req -new -newkey rsa:2048 -x509 -sha256 -nodes -out __cert.pem -keyout __key.pem --subj '/CN=US'
- The above command must not lead to a 'Segmentation fault (core dumped)',
rather than create a proper certificate file.
Also watch /var/log/syslog / journalctl for more details.
- Upgrade not only the openssl package itself,
but also libssl3, before verification.
- The issue is fixed in openssl 3.0.8 which landed in lunar.
[Where problems could occur]
I don't pretend to understand the lifecycle of providers in openssl3 but the patch is simple and has been widely tested by now, including on ubuntu. Thus, I see little chance an unexpected problem would occur with it.
[Patches]
The patches come directly from upstream and apply cleanly.

Further investigations point to this open issue on openssl repository https://github.com/openssl/openssl/issues/18578
The default_algorithms declaration of RAND and others has no effect on
the behaviour of this problem.
