RHEL Engineering is moving the tracking of its product development work on RHEL 6 through RHEL 9 to Red Hat Jira (issues.redhat.com). If you're a Red Hat customer, please continue to file support cases via the Red Hat customer portal. If you're not, please head to the "RHEL project" in Red Hat Jira and file new tickets here. Individual Bugzilla bugs in the statuses "NEW", "ASSIGNED", and "POST" are being migrated throughout September 2023. Bugs of Red Hat partners with an assigned Engineering Partner Manager (EPM) are migrated in late September as per pre-agreed dates. Bugs against components "kernel", "kernel-rt", and "kpatch" are only migrated if still in "NEW" or "ASSIGNED". If you cannot log in to RH Jira, please consult article #7032570. That failing, please send an e-mail to the RH Jira admins at rh-issues@redhat.com to troubleshoot your issue as a user management inquiry. The email creates a ServiceNow ticket with Red Hat. Individual Bugzilla bugs that are migrated will be moved to status "CLOSED", resolution "MIGRATED", and set with "MigratedToJIRA" in "Keywords". The link to the successor Jira issue will be found under "Links", have a little "two-footprint" icon next to it, and direct you to the "RHEL project" in Red Hat Jira (issue links are of type "https://issues.redhat.com/browse/RHEL-XXXX", where "X" is a digit). This same link will be available in a blue banner at the top of the page informing you that that bug has been migrated.

Description Jan Horak 2023-08-08 14:15:14 UTC
This bug was initially created as a copy of Bug #2229981

I am copying this bug because: 



Description of problem:
TLS is broken on the latest thunderbird release

Version-Release number of selected component (if applicable):
thunderbird-102.14.0-1.el7_9.x86_64

How reproducible:
Always

Steps to Reproduce:
1. Configure thunderbird to use TLS for pop3 or smtp connections
2. Update thunderbird to 102.14.0-1.el7_9.x86_64
3. Launch thunderbird and attempt tls connection

Actual results:
TLS connection fails with the following entry in maillog:

Aug  7 19:06:15 mail_server dovecot: pop3-login: Disconnected (no auth attempts in 0 secs): user=<>, rip=192.168.0.1, lip=192.168.0.1, TLS handshaking: SSL_accept() failed: error:14094412:SSL routines:ssl3_read_bytes:sslv3 alert bad certificate: SSL alert number 42, session=<ddk1GlkCBqjAqAAB>

Expected results:
tls connections work as expected

Additional info:
Downgrading to thunderbird-102.13.0-2.el7_9.x86_64 fixes the issue
Disabling SSL/TLS security and sending authentication in plain text (highly undesirable) also works
TLS cert is self signed and imported into thunderbird, with expiry date 2028
