Description

Steps to reproduce:

echo 0542073208036e646e080962726f6164636173740820$(makepasswd | openssl sha256 | awk '{print $2}')090214000a0483a975840c021388 \
| xxd -r -p | nc hobo.cs.arizona.edu 6363

This injects a malformed packets of structure:

Interest
  Name
    GenericNameComponent ndn
    GenericNameComponent broadcast
    GenericNameComponent [RANDOM]
  Selectors
    MetaInfo (empty)
  Nonce 0x83a97584
  InterestLifetime 5000

Expected: NFD drops the malformed packet.
Actual: persistent Interest loop occurs across the testbed.

This was observed on global testbed on 04 Sep 2019. Steps above were developed according to captured packet samples.
