Bit-fiddling pointers is technically implementation defined behavior
in the C specification so the following code is not supported in all
platforms:
PTR_SIZE_INT mask;
void * a, b, c;
int boolean_flag;
mask = 0 - boolean_flag;
/* Not guaranteed to be a valid ptr to a or b on all platforms */
a = (void *)
((((PTR_SIZE_INT) b & ~mask) | (((PTR_SIZE_INT)) c & mask)));
Using a ternary conditional operator is supported on all platforms
(i.e. `a = boolean_flag ? b : c;`).
On most modern compilers/CPUs, this will be faster, since it will
get converted to a CMOV instruction.

This is about a timing leak in the topmost limb
of the internal result of RSA_private_decrypt,
before the padding check.
There are in fact at least three bugs together that
caused the timing leak:
First and probably most important is the fact that
the blinding did not use the constant time code path
at all when the RSA object was used for a private
decrypt, due to the fact that the Montgomery context
rsa->_method_mod_n was not set up early enough in
rsa_ossl_private_decrypt, when BN_BLINDING_create_param
needed it, and that was persisted as blinding->m_ctx,
although the RSA object creates the Montgomery context
just a bit later.
Then the infamous bn_correct_top was used on the
secret value right after the blinding was removed.
And finally the function BN_bn2binpad did not use
the constant-time code path since the BN_FLG_CONSTTIME
was not set on the secret value.
In order to address the first problem, this patch
makes sure that the rsa->_method_mod_n is initialized
right before the blinding context.
And to fix the second problem, we add a new utility
function bn_correct_top_consttime, a const-time
variant of bn_correct_top.
Together with the fact, that BN_bn2binpad is already
constant time if the flag BN_FLG_CONSTTIME is set,
this should eliminate the timing oracle completely.
In addition the no-asm variant may also have
branches that depend on secret values, because the last
invocation of bn_sub_words in bn_from_montgomery_word
had branches when the function is compiled by certain
gcc compiler versions, due to the clumsy coding style.
So additionally this patch stream-lined the no-asm
C-code in order to avoid branches where possible and
improve the resulting code quality.

Function EVP_PKEY_get_bn_param() uses temporary buffer (on stack or

into BIGNUM*, the buffer is not erased and may contain sensitive data.
This change makes sure the buffer is erased if it was successfully
filled before. Unfortunately, it does not distinguish between public and
private key components, and will always erase the buffer.

This is especially bad if OPENSSL_init_crypto can recursively end up
attempting to call the RUN_ONCE that we're already inside.

There is no need to protect it "twice".

DSA_sign() assumes that the signature passed in is related to DSA_size().
If q is negative then DSA_size() actually fails and returns 0.
A test that tries to allocate the signature buffer using DSA_size() and then
pass it to DSA_sign() will then either.
(1) Have a signature buffer of NULL. In this case it was leaking data
returned via i2d_DSA_SIG.
(2) Cause a seg fault because we created a buffer that was not large
enough to hold the signature. As it already checked zero we also now
check for negative values also.
