4 years agoFix DTLS session ticket renewal
Matt Caswell [Thu, 13 Aug 2015 09:06:30 +0000 (10:06 +0100)]
Fix DTLS session ticket renewal

A DTLS client will abort a handshake if the server attempts to renew the
session ticket. This is caused by a state machine discrepancy between DTLS
and TLS discovered during the state machine rewrite work.

The bug can be demonstrated as follows:

Start a DTLS s_server instance:
openssl s_server -dtls

Start a client and obtain a session but no ticket:
openssl s_client -dtls -sess_out session.pem -no_ticket

Now start a client reusing the session, but allow a ticket:
openssl s_client -dtls -sess_in session.pem

The client will abort the handshake.

Fix SSL_set_session_ticket_ext when used with SSLv23_method

The function SSL_set_session_ticket_ext can be used to set custom session
ticket data passed in the initial ClientHello. This can be particularly
useful for EAP-FAST. However, when using SSLv23_method, the session does
not get created until the ServerHello has been received. The extension code

during creation of the ClientHello instead of waiting for the ServerHello.

Reject calls to X509_verify_cert that have not been reinitialised

The function X509_verify_cert checks the value of |ctx->chain| at the
beginning, and if it is NULL then it initialises it, along with the value
of ctx->untrusted. The normal way to use X509_verify_cert() is to first
call X509_STORE_CTX_init(); then set up various parameters etc; then call
X509_verify_cert(); then check the results; and finally call
X509_STORE_CTX_cleanup(). The initial call to X509_STORE_CTX_init() sets
|ctx->chain| to NULL. The only place in the OpenSSL codebase  where
|ctx->chain| is set to anything other than a non NULL value is in
X509_verify_cert itself. Therefore the only ways that |ctx->chain| could be
non NULL on entry to X509_verify_cert is if one of the following occurs:
1) An application calls X509_verify_cert() twice without re-initialising
in between.
2) An application reaches inside the X509_STORE_CTX structure and changes
the value of |ctx->chain| directly.

With regards to the second of these, we should discount this - it should
not be supported to allow this.

With regards to the first of these, the documentation is not exactly
crystal clear, but the implication is that you must call
X509_STORE_CTX_init() before each call to X509_verify_cert(). If you fail
to do this then, at best, the results would be undefined.

Calling X509_verify_cert() with |ctx->chain| set to a non NULL value is
likely to have unexpected results, and could be dangerous. This commit
changes the behaviour of X509_verify_cert() so that it causes an error if
|ctx->chain| is anything other than NULL (because this indicates that we
have not been initialised properly). It also clarifies the associated
documentation. This is a follow up commit to CVE-2015-1793.

Fix alternate chains certificate forgery issue

During certificate verfification, OpenSSL will attempt to find an
alternative certificate chain if the first attempt to build such a chain
fails. An error in the implementation of this logic can mean that an
attacker could cause certain checks on untrusted certificates to be
bypassed, such as the CA flag, enabling them to use a valid leaf
certificate to act as a CA and "issue" an invalid certificate.

This occurs where at least one cert is added to the first chain from the
trust store, but that chain still ends up being untrusted. In that case

Fix race condition in NewSessionTicket

If a NewSessionTicket is received by a multi-threaded client when
attempting to reuse a previous ticket then a race condition can occur
potentially leading to a double free of the ticket data.

CVE-2015-1791

This also fixes RT#3808 where a session ID is changed for a session already
in the client session cache. Since the session ID is the key to the cache
this breaks the cache access.

4 years agoClear state in DTLSv1_listen
Matt Caswell [Mon, 9 Mar 2015 16:09:04 +0000 (16:09 +0000)]
Clear state in DTLSv1_listen

This is a backport of commit e83ee04bb7de800cdb71d522fa562e99328003a3 from
the master branch (and this has also been applied to 1.0.2). In 1.0.2 this
was CVE-2015-0207. For other branches there is no known security issue, but
this is being backported as a precautionary measure.

The DTLSv1_listen function is intended to be stateless and processes
the initial ClientHello from many peers. It is common for user code to
loop over the call to DTLSv1_listen until a valid ClientHello is received
with an associated cookie. A defect in the implementation of DTLSv1_listen
means that state is preserved in the SSL object from one invokation to the
next.

4 years agoCheck the message type requested is the type received in DTLS
Matt Caswell [Fri, 29 May 2015 16:05:01 +0000 (17:05 +0100)]
Check the message type requested is the type received in DTLS

dtls1_get_message has an |mt| variable which is the type of the message that
is being requested. If it is negative then any message type is allowed.
However the value of |mt| is not checked in one of the main code paths, so a
peer can send a message of a completely different type and it will be
processed as if it was the message type that we were expecting. This has
very little practical consequences because the current behaviour will still
fail when the format of the message isn't as expected.
