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.

The same issue on rhel-6.

+++ This bug was initially created as a clone of Bug #1239150 +++

Description of problem:
When dissecting TLS 1.2 protocol traffic, the Handshake message Certificate Verify is not dissected in detail.

Version-Release number of selected component (if applicable):
wireshark-1.10.3-12.el7_0.x86_64

How reproducible:
Always

Steps to Reproduce:
1. tshark -o 'ssl.desegment_ssl_records:TRUE' -r capture.pcap -V -d tcp.port==4433,ssl | grep -A10 "Certificate Verify"

Actual results:
        Handshake Protocol: Certificate Verify
            Handshake Type: Certificate Verify (15)
            Length: 75
    TLSv1.2 Record Layer: Change Cipher Spec Protocol: Change Cipher Spec

Expected results:
        Handshake Protocol: Certificate Verify
            Handshake Type: Certificate Verify (15)
            Length: 75
            Signature Hash Algorithm: 0x0402
                Signature Hash Algorithm Hash: SHA256 (4)
                Signature Hash Algorithm Signature: DSA (2)
            Signature length: 71
            Signature: 3045022044efb28004eb6107bf7fb42e053cd86d82033b3b...

Additional info:
The functionality is present in rather old upstream development snapshot - Version 1.99.6 (v1.99.6rc0-158-g356e9c4 from master).

Haven't checked GUI, it may have the same problem.
