Description Jaroslav Aster 2015-07-07 13:40:52 UTC

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...
    TLSv1.2 Record Layer: Change Cipher Spec Protocol: Change Cipher Spec

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.
