Asterisk 1.4.31 IAX2/RSA BUG
If "A" tries to register on "B" and the RSA key from
"A" does not match the
key on "inkeys" on "B", "B" do not send a
"REGREJ", instead it sends a
"REGAUTH" with a new "CHALLENGE", then "A" send a
new "REGREQ" for this
"CHALLENGE" with the same wrong RSA key and it loops forever on this
(with a
storm of REGREQ <--> REGAUTH packets).
The same was true in version 1.2.31.1, but was corrected in a patch. (see
issue 14386 <https://issues.asterisk.org/view.php?id=14386>).
I tested some patches but nothing worked.
The console from the server ("B") will be flooded with this:
