the product is no longer active in Red Hat Bugzilla.
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.

*** Fatal error: Internal error in memory allocation.
*** Handshake has failed
GnuTLS error: Internal error in memory allocation.
Expected results:
A working SSL connection. (Or at least a sane error message)
Additional info:
The same command works on Fedora 31 and 32.
`openssl s_client -connect imap.mail.yahoo.com:993` succeeds on CentOS 7.
I confirm the same error with gnutls-cli 3.5.18 on Ubuntu 18.04.
I can get a working connection on CentOS and Ubuntu with `gnutls-cli --disable-extensions -p 995 pop.verizon.net`. I also get a connection on Ubuntu with `gnutls-cli --priority 'NORMAL:%NO_TICKETS' -p 993 imap.mail.yahoo.com`, but that produces 'Syntax error at: %NO_TICKETS' on CentOS.
Thank you for the bug report. While this bug is reported against RHEL-7.8, RHEL-7 is already in the Maintenance Support Phase 1, which means only qualified Critical and Important Security errata advisories (RHSAs) and Urgent Priority Bug Fix errata advisories (RHBAs) may be released. If this bug is qualified for the Maintenance Support 1 Phase, please reopen; otherwise, we recommend moving the request to Red Hat Enterprise Linux 8.
People are unable to read their email due to this bug. From any practical point of view, that qualifies as a critical bug. Please incorporate the gnutls fix in RHEL-7 updates. Me for one, I use CentOS which has a much longer lifespan than RHEL, but it relies un RHEL packages and fixes.
