TerminateProcess is asynchronous, so the code as written in the above
commit is not correct (and doesn't even compile at the moment). It is
also probably not needed in the speed case. Reverting in order to figure
out the correct solution.

Manual cherry-pick of 538860a3.

The selector field could be omitted because it has a DEFAULT value.
In this case *sfld == NULL (sfld can never be NULL). This was not
noticed because this was never used in existing ASN.1 modules.

The TS_RESP_verify_response() function is used for verifying the response
from a TSA. You can set the provided TS_VERIFY_CTX with different flags
depending on what aspects of the response you wish to verify.

A seg fault will occur if you supply the TS_VFY_SIGNER or TS_VFY_TSA_NAME
flags without also specifying TS_VFY_SIGNATURE.

The previous commit fixed a bug with BN_mod_word() which would have been
caught if we had a test for it. This commit adds one.

Reviewed-by: Andy Polyakov <appro@openssl.org>

On systems where we do not have BN_ULLONG (e.g. typically 64 bit systems)
then BN_mod_word() can return incorrect results if the supplied modulus is

CVE-2016-2178

Reviewed-by: Rich Salz <rsalz@openssl.org>

Operations in the DSA signing algorithm should run in constant time in
order to avoid side channel attacks. A flaw in the OpenSSL DSA
implementation means that a non-constant time codepath is followed for
certain operations. This has been demonstrated through a cache-timing
attack to be sufficient for an attacker to recover the private DSA key.

According to the x509 man page in the section discussing -certopt it says
that the ca_default option is the same as that used by the ca utility and
(amongst other things) has the effect of suppressing printing of the
signature - but in fact it doesn't. This error seems to have been present
since the documentation was written back in 2001. It never had this effect.

The default config file sets the certopt value to ca_default. The ca utility
takes that and THEN adds additional options to suppress printing of the
signature. So the ca utility DOES suppress printing of the signature - but
it is not as a result of using the ca_default option.

If the string to print is exactly 2048 character long (excluding the NULL
terminator) then BIO_printf will chop off the last byte. This is because
it has filled its static buffer but hasn't yet allocated a dynamic buffer.
In cases where we don't have a dynamic buffer we need to truncate but that
is not the case for BIO_printf(). We need to check whether we are able to
have a dynamic buffer buffer deciding to truncate.
