* origin/topic/bernhard/ssl-analyzer:
Fix a few failing tests
Add very basic ocsp stapling support.
Add documentation, consts and tests for the new events.
Support parsing of several TLS extensions.
Make SSL/TLS version detection less brittle.
Nicer notices for heartbleed.
rip out state handline from ssl analyzer.
enable detection of encrypted heartbleeds.
also extract payload data in ssl_heartbeat
add to local.bro, add disclaimer
make tls heartbeat messages a bit better.
fix tabs.
polish script and probably detect encrypted attacks too.
detect and alert on simple case of heartbleed
default to TLS when not being able to determine version
add is_orig to heartbeat event
Throw new event for heartbeat messages.
BIT-1178 #merged
At the moment, we have support for:
elliptic_curves: client supported elliptic curves
ec_point_formats: list of client supported EC point formats
application_layer_protocol_negotiation: list of supported application layer protocols (used for spdy/http2 negotiation)
server_name: server name sent by client. This was supported before, but... a bit brittle.
This still cannot deal with v2 hellos that use the long length.
On the other hand - OpenSSL also cannot deal with these and we should
not see many sslv2 connections in any case - so... they probably
would not work in practice in any case.
An unsized array already parses indefinitely. &until($element <= 0)
just causes nonsense code to be generated. I.e. checking a pointer that
can never even be null against <= 0. And the compare would happen after
delete'ing the pointer, making it even odder (though still benign).
- Thanks for help from Rafal Lesniak in nailing down the location
of the bug and supplying test traffic.
- Test traffic with a TLS 1.2 connection.
- Addresses ticket #1020
