Bug ID: 13025 Summary: Relay Data option is not allowed in Bulk Leasequery reply Product: Wireshark Version: 2.2.1 Hardware: x86 OS: macOS 10.12 Status: UNCONFIRMED Severity: Major Priority: Low Component: Dissection engine (libwireshark) Assignee: bugzilla-ad...@wireshark.org Reporter: hoon...@gmail.com Build Information: Version 2.2.1 (v2.2.1-0-ga6fbd27 from master-2.2) Copyright 1998-2016 Gerald Combs <ger...@wireshark.org> and contributors.

Running on Mac OS X 10.12, build 16A323 (Darwin 16.0.0), with locale C, with libpcap version 1.7.4 - Apple version 67, with GnuTLS 2.12.19, with Gcrypt 1.5.0, with zlib 1.2.8. Intel(R) Core(TM) i5 CPU M 520 @ 2.40GHz (with SSE4.2) Built using llvm-gcc 4.2.1 (Based on Apple Inc. build 5658) (LLVM build 2336.9.00). -- when dhcpv6 dissector analyzes the Leasequery Relay Data option in the DHCPv6 Bulk Leasequery, it flags the option as a malformed and treats the DHCP-relay-message value in it as ASCII-characters not the Relay Message option. The Bulk Leasequery protocol[RFC 5460] extends Leasequery protocol[RFC5007]. so I think the dissector is able to allow Bulk Leasequery reply messages to contain the Relay Data option.
