Description of problem: If the connection uses TLSv1.2 the Wireshark GUI can't decode the TLS Handshake Protocol Server Key Exchange messages in ECDHE or DHE key exchange, it can do that only if the connection uses TLSv1.0. Decoding of Server Key Exchange using the CLI tshark command always fails. Version-Release number of selected component (if applicable): wireshark-1.8.10-17.el6.x86_64 How reproducible: Always Steps to Reproduce: 1. Open wireshark load tlsv1.2-ecdhe-rsa.pcapng 1. tshark -o 'ssl.desegment_ssl_records:TRUE' -d tcp.port==4433,ssl -r /tmp/ -V tlsv1.0-dhe-rsa.pcapng | grep -A 6 'Server Key Exchange' Actual results: Handshake Protocol: Server Key Exchange Handshake Type: Server Key Exchange (12) Length: 199 Expected results: Handshake Protocol: Server Key Exchange Handshake Type: Server Key Exchange (12) Length: 199 EC Diffie-Hellman Server Params curve_type: named_curve (0x03) named_curve: secp256r1 (0x0017) Pubkey Length: 65 pubkey:f00ba2... etc. Additional info: See bug 1222600 for example packet captures
