Deprecate RAND_pseudo_bytes
The justification for RAND_pseudo_bytes is somewhat dubious, and the reality
is that it is frequently being misused. RAND_bytes and RAND_pseudo_bytes in
the default implementation both end up calling ssleay_rand_bytes. Both may
return -1 in an error condition. If there is insufficient entropy then
both will return 0, but RAND_bytes will additionally add an error to the
error queue. They both return 1 on success.
Therefore the fundamental difference between the two is that one will add an
error to the error queue with insufficient entory whilst the other will not.
Frequently there are constructions of this form:
if(RAND_pseudo_bytes(...) <= 1)
goto err;
In the above form insufficient entropy is treated as an error anyway, so
RAND_bytes is probably the better form to use.
This form is also seen:
if(!RAND_pseudo_bytes(...))
goto err;
This is technically not correct at all since a -1 return value is
incorrectly handled - but this form will also treat insufficient entropy as
an error.
Within libssl it is required that you have correctly seeded your entropy
pool and so there seems little benefit in using RAND_pseudo_bytes.
Similarly in libcrypto many operations also require a correctly seeded
entropy pool and so in most interesting cases you would be better off
using RAND_bytes anyway. There is a significant risk of RAND_pseudo_bytes
being incorrectly used in scenarios where security can be compromised by
insufficient entropy.
If you are not using the default implementation, then most engines use the
same function to implement RAND_bytes and RAND_pseudo_bytes in any case.
Given its misuse, limited benefit, and potential to compromise security,
RAND_pseudo_bytes has been deprecated.

In ssl3_send_new_session_ticket the message to be sent is constructed. We
skip adding the length of the session ticket initially, then call

ticket. Unfortunately, in DTLS, ssl_set_handshake_header also has the side
effect of buffering the message for subsequent retransmission if required.

message that is buffered is incomplete, causing an invalid message to be

- crypto_128_unwrap_raw()'s return value ('ret') is checked incorrectly,
and the function immediately returns 'ret' in (almost) all cases.
This makes the IV checking code later in the function unreachable, but
callers think the IV check succeeded since CRYPTO_128_unwrap()'s
return value is non-zero.
FIX: Return 0 (error) if crypto_128_unwrap_raw() returned 0 (error).
- crypto_128_unwrap_raw() writes the IV to the 'got_iv' buffer, not to
the first 8 bytes of the output buffer ('out') as the IV checking code
expects. This makes the IV check fail.
FIX: Compare 'iv' to 'got_iv', not 'out'.
- The data written to the output buffer ('out') is "cleansed" if the IV
check fails, but the code passes OPENSSL_cleanse() the input buffer
length ('inlen') instead of the number of bytes that
crypto_128_unwrap_raw() wrote to the output buffer ('ret'). This
means that OPENSSL_cleanse() could potentially write past the end of
'out'.
FIX: Change 'inlen' to 'ret' in the OPENSSL_cleanse() call.
- CRYPTO_128_unwrap() is returning the length of the input buffer
('inlen') instead of the number of bytes written to the output buffer
('ret'). This could cause the caller to read past the end of 'out'.
FIX: Return 'ret' instead of 'inlen' at the end of the function.

PKCS#7: avoid NULL pointer dereferences with missing content
In PKCS#7, the ASN.1 content component is optional.
This typically applies to inner content (detached signatures),
however we must also handle unexpected missing outer content
correctly.
This patch only addresses functions reachable from parsing,
decryption and verification, and functions otherwise associated
with reading potentially untrusted data.
Correcting all low-level API calls requires further work.

Fix Seg fault in DTLSv1_listen
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 that can lead to a segmentation fault. Erorrs processing the initial
ClientHello can trigger this scenario. An example of such an error could
be that a DTLS1.0 only client is attempting to connect to a DTLS1.2 only
server.

Multiblock corrupted pointer fix
OpenSSL 1.0.2 introduced the "multiblock" performance improvement. This
feature only applies on 64 bit x86 architecture platforms that support AES
NI instructions. A defect in the implementation of "multiblock" can cause
OpenSSL's internal write buffer to become incorrectly set to NULL when
using non-blocking IO. Typically, when the user application is using a
socket BIO for writing, this will only result in a failed connection.
However if some other BIO is used then it is likely that a segmentation
fault will be triggered, thus enabling a potential DoS attack.

Correct the request of debug builds
./config would translate -d into having the target get a 'debug-'
prefix, and then run './Configure LIST' to find out if such a
debugging target exists or not.
With the recent changes, the separate 'debug-foo' targets are
disappearing, and we're giving the normal targets debugging
capabilities instead. Unfortunately, './config' wasn't changed to
match this new behavior.
This change introduces the arguments '--debug' and '--release' - the
latter just for orthogonality - to ./Configure, and ./config now
treats -d by adding '--debug' to the options for ./Configure.
