[Bug 1234405] New: devel:microos/libeconf: Bug libeconf 0.7.5 causes systemd/sddm/pam/libc crash and prevents login
https://bugzilla.suse.com/show_bug.cgi?id=1234405 Bug ID: 1234405 Summary: devel:microos/libeconf: Bug libeconf 0.7.5 causes systemd/sddm/pam/libc crash and prevents login Classification: openSUSE Product: openSUSE.org Version: unspecified Hardware: Other OS: Other Status: NEW Severity: Normal Priority: P5 - None Component: 3rd party software Assignee: rbrown@suse.com Reporter: pallaswept@proton.me QA Contact: screening-team-bugs@suse.de Target Milestone: --- Found By: --- Blocker: --- Created attachment 879108 --> https://bugzilla.suse.com/attachment.cgi?id=879108&action=edit output of `journalctl -b -2 |rg dumped -A 40` After today's dup, I rebooted to a desktop with a mouse cursor and otherwise unresponsive. Switching to a TTY showed an error "Unable to start user manager for user 1000". I was unable to login with any account including root. Using the recovery console, I was able to retrieve logs, find this culprit, rollback, and am currently working after locking out the libeconf updates with `sudo zypper al libeconf0 libeconf0-32bit libeconf-devel` Not sure if this is just me, hopefully it is. I did have some custom pam config, which I naturally removed to test, and there was no change, but I did notice that `rpm -qf /etc/pam.d/*` returns several "file foo is not owned by any package", and none of those files are mine. I'm not sure if this is intentional or if it is related. Relevant section of the journal is attached. Please let me know if I can help in any way. -- You are receiving this mail because: You are on the CC list for the bug.

Could you please add your /usr/etc/security/pam_env.conf and /etc/security/pam_env.conf Perhaps I can reproduce it......
Thanks Stefan, The first file is all commented out (it's unchanged from stock) and the second file does not exist. -- You are receiving this mail because: You are on the CC list for the bug.
