From Aditya Ambadkar via https://bugs.wireshark.org/bugzilla/show_bug.cgi?id=7046 :
Fix CID 703472 and (external) fuzz failure 7567:
The dissect_subtlv_interface_parameters is missing the handling of BFD 2..4.
For the crash patch, we decided to add the bfd2..4 in dissect_tlc function(in
the diff). We plan to open a separate bug to fix
dissect_subtlv_interface_parameters to make it handle BFD2..4. (Thanks to Arun
Arunachalam for this analysis)
From me: fix up some indentation and replace tabs with spaces (for consistency).
