The following errata report has been submitted for RFC7158,
"The JavaScript Object Notation (JSON) Data Interchange Format".

Notes
-----
This is a followup to my previous errata. I just wanted to note that this should also be discusssed in the security considerations.

Consider a protocol that would allow back-to-back json messages. For example, a banking protocol that accepted currency amounts.

A RFC7158 encoder could now encode the two separate amounts "1" and "999" and end up with the single amount "1999", which couldn't happen with the original JSON specification.

Since this affects existing protocols and could potentially result in serious misinterpretations, I think noting this in the security considerations sections would be prudent.

Instructions:

This errata is currently posted as "Reported". If necessary, please
use "Reply All" to discuss whether it should be verified or
rejected. When a decision is reached, the verifying party (IESG)
