It should not be possible for DTLS message fragments to span multiple packets. However previously if the message header fitted exactly into one packet, and the fragment body was in the next packet then this would work. Obviously this would fail if packets get re-ordered mid-flight. Reviewed-by: Tim Hudson <tjh@openssl.org>

The function EC_POINT_is_on_curve does not return a boolean value. It returns 1 if the point is on the curve, 0 if it is not, and -1 on error. Many usages within OpenSSL were incorrectly using this function and therefore not correctly handling error conditions. With thanks to the Open Crypto Audit Project for reporting this issue.

This fixes a memory leak that can occur whilst duplicating a BIO chain if the call to CRYPTO_dup_ex_data() fails. It also fixes a second memory leak where if a failure occurs after successfully creating the first BIO in the chain, then the beginning of the new chain was not freed.

For librypto to be complete, the stuff in both crypto/ and engines/ have to be built. Doing 'make test' or 'make apps' from a clean source tree failed to do so.

There's a need for a target that will build all of libcrypto, so let's add 'build_libcrypto' that does this. For ortogonality, let's also add 'build_libssl'. Have both also depend on 'libcrypto.pc' and 'libssl.pc' so those get built together with the libraries. This makes 'all' depend on fewer things directly.

A BIGNUM can have the value of -0. The function BN_bn2hex fails to account for this and can allocate a buffer one byte too short in the event of -0 being used, leading to a one byte buffer overrun. All usage within the OpenSSL library is considered safe. Any security risk is considered negligible. With thanks to Mateusz Kocielski (LogicalTrust), Marek Kroemeke and Filip Palian for discovering and reporting this issue.

The session object on the client side is initially created during construction of the ClientHello. If the client is DTLS1.2 capable then it will store 1.2 as the version for the session. However if the server is only DTLS1.0 capable then when the ServerHello comes back the client switches to using DTLS1.0 from then on. However the session version does not get updated. Therefore when the client attempts to resume that session the server throws an alert because of an incorrect protocol version.

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. Parts of this patch were inspired by this Akamai change: https://github.com/akamai/openssl/commit/c0bf69a791239ceec64509f9f19fcafb2461b0d3 Reviewed-by: Rich Salz <rsalz@openssl.org>
