The following errata report has been verified for RFC6274,
"Security Assessment of the Internet Protocol Version 4".

You may review the report below and at:
https://www.rfc-editor.org/errata/eid7887

--------------------------------------
Status: Verified
Type: Editorial

Reported by: Niklas Baerveldt <niklas.baerveldt@gmail.com>
Date Reported: 2024-04-08
Verified by: RFC Editor  

Section: .8.4

Original Text
-------------
   The attacker is:

   o  Four hops away from A.

   o  Four hops away from B.

   o  Four hops away from C.

   o  Four hops away from D.

   In the network setup of Figure 3, the only system that satisfies all
   these conditions is the one marked as the "F".


Corrected Text
--------------
   The attacker is:

   o  Four hops away from A.

   o  Four hops away from B.

   o  Four hops away from C.

   o  Three hops away from D.

   In the network setup of Figure 6, the only system that satisfies all
   these conditions is the one marked as the "F".


Notes
-----
Since the packets that D gets has a TTL of 62 while A,B and C gets packets with TTL of 61, it should be that D is one less hop away than the others. This also seems to be illustrated in Figure 6.

Text that seems to refer to the network setup of Figure 6 references to incorrect figure number 3.
