Fix DTLSv1_listen() sequence numbers

DTLSv1_listen() is stateless. We never increment the record read sequence

write sequence.

The logic for doing the write sequence reflection was *after* we had
finished processing the incoming ClientHello and before we write the
ServerHello. In the normal course of events this is fine. However if we
need to write an early alert during ClientHello processing (e.g. no shared
cipher), then we haven't done the write sequence reflection yet. This means
the alert gets written with the wrong sequence number (it will just be set
to whatever value we left it in the last time we wrote something). If the
sequence number is less than expected then the client will believe that the
incoming alert is a retransmit and will therefore drop it, causing the
client to hang waiting for a response from the server.

7 years agoDon't read uninitialised data for short session IDs.
David Benjamin [Thu, 9 Feb 2017 20:13:13 +0000 (15:13 -0500)]
Don't read uninitialised data for short session IDs.

While it's always safe to read |SSL_MAX_SSL_SESSION_ID_LENGTH| bytes
from an |SSL_SESSION|'s |session_id| array, the hash function would do
so with without considering if all those bytes had been written to.

This change checks |session_id_length| before possibly reading
uninitialised memory. Since the result of the hash function was already
attacker controlled, and since a lookup of a short session ID will
always fail, it doesn't appear that this is anything more than a clean
up.

In particular, |ssl_get_prev_session| uses a stack-allocated placeholder
|SSL_SESSION| as a lookup key, so the |session_id| array may be
uninitialised.

This was originally found with libFuzzer and MSan in
https://boringssl.googlesource.com/boringssl/+/e976e4349d693b4bbb97e1694f45be5a1b22c8c7,
then by Robert Swiecki with honggfuzz and MSan here. Thanks to both.

Fix session ticket and SNI

When session tickets are used, it's possible that SNI might swtich the
SSL_CTX on an SSL. Normally, this is not a problem, because the
initial_ctx/session_ctx are used for all session ticket/id processes.

However, when the SNI callback occurs, it's possible that the callback
may update the options in the SSL from the SSL_CTX, and this could
cause SSL_OP_NO_TICKET to be set. If this occurs, then two bad things
can happen:

1. The session ticket TLSEXT may not be written when the ticket expected
flag is set. The state machine transistions to writing the ticket, and
the client responds with an error as its not expecting a ticket.
2. When creating the session ticket, if the ticket key cb returns 0
the crypto/hmac contexts are not initialized, and the code crashes when
trying to encrypt the session ticket.

To fix 1, if the ticket TLSEXT is not written out, clear the expected
ticket flag.
To fix 2, consider a return of 0 from the ticket key cb a recoverable
error, and write a 0 length ticket and continue. The client-side code
can explicitly handle this case.

Fix these two cases, and add unit test code to validate ticket behavior.

- dont call ASN1_item_ex_free if ASN1_OP_NEW_PRE failed.

Reworked error handing in x509_name_ex_d2i and x509_name_encode.
