Hi Magnus -

Marc responded earlier so you may have missed it. Below is his response:

+++++++++++
This errata is correct, and there is nobody to blame for that mistake but me.

Magnus, how to you want to proceed for the recomputed test vector?

Thanks.
+++++++++++

Cheers,

Gonzalo

The following errata report has been submitted for RFC8489,
"Session Traversal Utilities for NAT (STUN)".

Type: Technical
Reported by: Jared Williams <renthraysk@gmail.com<mailto:renthraysk@gmail.com>>

Section: Appendix B.1

Original Text
-------------
00 01 00 9c      Request type and message length


Corrected Text
--------------
00 01 00 88      Request type and message length

Notes
-----
The message length in the test vector (9c) is the absolute length of the whole
test vector. However from section 5. STUN Message Structure

"The message length MUST contain the size of the message in bytes, not
  including the 20-byte STUN header."

So the message length in the header should be 20 less than absolute length of
the whole message.

0x9C - 20, 0x88.

Also the MESSAGE-INTEGRITY-SHA256 HMAC-SHA256 value of the Test Vector will
need recomputing.

Instructions:
-------------
This erratum 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
can log in to change the status and edit the report, if necessary.
