Fix DTLS replay protection The DTLS implementation provides some protection against replay attacks in accordance with RFC6347 section 4.1.2.6. A sliding "window" of valid record sequence numbers is maintained with the "right" hand edge of the window set to the highest sequence number we have received so far. Records that arrive that are off the "left" hand edge of the window are rejected. Records within the window are checked against a list of records received so far. If we already received it then we also reject the new record. If we have not already received the record, or the sequence number is off the right hand edge of the window then we verify the MAC of the record. If MAC verification fails then we discard the record. Otherwise we mark the record as received. If the sequence number was off the right hand edge of the window, then we slide the window along so that the right hand edge is in line with the newly received sequence number. Records may arrive for future epochs, i.e. a record from after a CCS being sent, can arrive before the CCS does if the packets get re-ordered. As we have not yet received the CCS we are not yet in a position to decrypt or validate the MAC of those records. OpenSSL places those records on an unprocessed records queue. It additionally updates the window immediately, even though we have not yet verified the MAC. This will only occur if currently in a handshake/renegotiation. This could be exploited by an attacker by sending a record for the next epoch (which does not have to decrypt or have a valid MAC), with a very large sequence number. This means the right hand edge of the window is moved very far to the right, and all subsequent legitimate packets are dropped causing a denial of service. A similar effect can be achieved during the initial handshake. In this case there is no MAC key negotiated yet. Therefore an attacker can send a message for the current epoch with a very large sequence number. The code will process the record as normal. If the hanshake message sequence number (as opposed to the record sequence number that we have been talking about so far) is in the future then the injected message is bufferred to be handled later, but the window is still updated. Therefore all subsequent legitimate handshake records are dropped. This aspect is not considered a security issue because there are many ways for an attacker to disrupt the initial handshake and prevent it from completing successfully (e.g. injection of a handshake message will cause the Finished MAC to fail and the handshake to be aborted). This issue comes about as a result of trying to do replay protection, but having no integrity mechanism in place yet. Does it even make sense to have replay protection in epoch 0? That issue isn't addressed here though. This addressed an OCAP Audit issue. CVE-2016-2181 Reviewed-by: Richard Levitte <levitte@openssl.org>

DTLSv1_listen rewrite The existing implementation of DTLSv1_listen() is fundamentally flawed. This function is used in DTLS solutions to listen for new incoming connections from DTLS clients. A client will send an initial ClientHello. The server will respond with a HelloVerifyRequest containing a unique cookie. The client the responds with a second ClientHello - which this time contains the cookie. Once the cookie has been verified then DTLSv1_listen() returns to user code, which is typically expected to continue the handshake with a call to (for example) SSL_accept(). Whilst listening for incoming ClientHellos, the underlying BIO is usually in an unconnected state. Therefore ClientHellos can come in from *any* peer. The arrival of the first ClientHello without the cookie, and the second one with it, could be interspersed with other intervening messages from different clients. The whole purpose of this mechanism is as a defence against DoS attacks. The idea is to avoid allocating state on the server until the client has verified that it is capable of receiving messages at the address it claims to come from. However the existing DTLSv1_listen() implementation completely fails to do this. It attempts to super-impose itself on the standard state machine and reuses all of this code. However the standard state machine expects to operate in a stateful manner with a single client, and this can cause various problems. A second more minor issue is that the return codes from this function are quite confused, with no distinction made between fatal and non-fatal errors. Most user code treats all errors as non-fatal, and simply retries the call to DTLSv1_listen(). This commit completely rewrites the implementation of DTLSv1_listen() and provides a stand alone implementation that does not rely on the existing state machine. It also provides more consistent return codes. Reviewed-by: Andy Polyakov <appro@openssl.org>
