           Summary: RTCP RTPFB dissector fails to properly dissect FCI for
                    unknown types.
           Product: Wireshark
           Version: SVN
          Platform: Other
        OS/Version: All
            Status: NEW
          Severity: Normal
          Priority: Low
         Component: Wireshark
        AssignedTo: wireshark-bugs@xxxxxxxxxxxxx
        ReportedBy: olivier.crete@xxxxxxxxx


Build Information:
revision 36208
--
The RTCP RTPFB dissector puts the wrong length parameter when trying to add an
unknown FCI.

Attached patch fixes the problem by replacing:
  packet_length - offset
with:
  start_offset + packet_length - offset
as the length argument of proto_tree_add_item()
