In param_build.c, the functions OSSL_PARAM_BLD_push_utf8_string() and
OSSL_PARAM_BLD_push_utf8_ptr() use strlen() to compute the length of
the string when bsize is zero. However, the size_t returned by
strlen() might be too large (it is stored in an intermediate "int"),
so check for that.
There are analogous functions in params.c, but they do not use an
intermediate "int" to store the size_t returned by strlen(). So there
is some inconsistency between the implementations.
Credit to Viktor D and Tomas M for spotting these missing checks.

sscanf can return -1 on an empty input string. We need to appropriately
handle such an invalid case.
The instance in OSSL_HTTP_parse_url could cause an uninitialised read of
sizeof(unsigned int) bytes (typically 4). In many cases this uninit read
will immediately fail on the following check (i.e. if the read value
>65535).
If the top 2 bytes of a 4 byte unsigned int are zero then the value will
be <=65535 and the uninitialised value will be returned to the caller and
could represent arbitrary data on the application stack.
The OpenSSL security team has assessed this issue and consider it to be
a bug only (i.e. not a CVE).

If p is set to 1 when calling BN_GF2m_mod_inv then an infinite loop will
result. Calling this function set 1 when applications call this directly
is a non-sensical value - so this would be considered a bug in the caller.
It does not seem possible to cause OpenSSL internal callers of
BN_GF2m_mod_inv to call it with a value of 1.
So, for the above reasons, this is not considered a security issue.

The little-endian optimization is doing some type-punning in a way
violating the C standard aliasing rule by loading or storing through a
lvalue with type "unsigned int" but the memory location has effective
type "unsigned long" or "unsigned long long" (BN_ULONG). Convert these
accesses to use memcpy instead, as memcpy is defined as-is "accessing
through the lvalues with type char" and char is aliasing with all types.
GCC does a good job to optimize away the temporary copies introduced
with the change. Ideally copying to a temporary unsigned int array,
doing the calculation, and then copying back to `r_d` will make the code
look better, but unfortunately GCC would fail to optimize away this
temporary array then.
I've not touched the LE optimization in BN_nist_mod_224 because it's
guarded by BN_BITS2!=64, then BN_BITS2 must be 32 and BN_ULONG must be
unsigned int, thus there is no aliasing issue in BN_nist_mod_224.

The low level SHA3_Squeeze() function needed to change slightly so
that it can handle multiple squeezes. This involves changing the
assembler code so that it passes a boolean to indicate whether
the Keccak function should be called on entry.
At the provider level, the squeeze is buffered, so that it only requests
a multiple of the blocksize when SHA3_Squeeze() is called. On the first
call the value is zero, on subsequent calls the value passed is 1.
