Description

NFD crashes if it receives the following sequence of packets:

  1. NFD receives a TCP packet with SYN,ECN,CWR flags, Seq=x.
  2. NFD responds a TCP packet with SYN and ACK flags, Seq=y.
  3. NFD receives a TCP packet with ACK flag, Seq=x+1, Ack=y+1.
  4. NFD receives a TCP packet with RST,ACK flags, Seq=x+1, Ack=y+1.

Updated by Junxiao Shi over 3 years ago

The bug was captured on my home router. The IP sending the packets in question was either an attacker or a vulnerability scanner.
I have attached the packet trace that triggered the bug on my system.

Moreover, I made a small program to transmit the sequence of packets.
It can reliably crash both the current NFD release (one of the testbed routers) and the latest nightly build (both my home router and a Docker container on my test server).
However, it seems that the reproduce program works only if the packets are transmitted over the Internet, and does not work in a local area network, indicating that the problem might be timing related.

I am able to obtain a stack trace on the test server, by setting breakpoint on boost::system::system_error::system_error.
The three errors appear consecutively after the packets were transmitted, and then NFD process exits.
