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 of problem:
When using gnutls-cli-debug to look at a openssl server, the application crashes

Version-Release number of selected component (if applicable):
gnutls-2.8.5-19.el6_7.x86_64
gnutls-utils-2.8.5-19.el6_7.x86_64

How reproducible:
Always

Steps to Reproduce:
1. openssl req -x509 -newkey rsa -keyout localhost.key -out localhost.crt -nodes -batch -subj /CN=localhost
2. openssl s_server -cert localhost.crt -key localhost.key
3. gnutls-cli-debug -d 100 -p 4433 localhost4

Actual results:
Resolving 'localhost'...
Connecting to '127.0.0.1:4433'...
|<2>| ASSERT: gnutls_priority.c:812
Error in %INITIAL_SAFE_RENEGOTIATION
Checking for Safe renegotiation support...

Expected results:
test successful, application not aborted

Additional info:
Disabling TLS1.2 support or enabling legacy renegotiation on server side doesn't make a difference

This is addressed by the 2.12.x rebase
