If the application provides custom memory allocations functions via
CRYPTO_set_mem_functions() then those should be used instead something
else like posix_memalign(). The applications might verify alloc and free
calls and pointers from posix_memalign() were never returned by the
implementations.
At least stunnel4 complains here.
Use posix_memalign() or if aligned_alloc() only if the application did
not provide a custom malloc() implementation. In case of a custom
implementation use CRYPTO_malloc() and align the memory accordingly.

The BN_GF2m_poly2arr() function converts characteristic-2 field
(GF_{2^m}) Galois polynomials from a representation as a BIGNUM bitmask,
to a compact array with just the exponents of the non-zero terms.
These polynomials are then used in BN_GF2m_mod_arr() to perform modular
reduction. A precondition of calling BN_GF2m_mod_arr() is that the
polynomial must have a non-zero constant term (i.e. the array has `0` as
its final element).
Internally, callers of BN_GF2m_poly2arr() did not verify that
precondition, and binary EC curve parameters with an invalid polynomial
could lead to out of bounds memory reads and writes in BN_GF2m_mod_arr().
The precondition is always true for polynomials that arise from the
standard form of EC parameters for characteristic-two fields (X9.62).
See the "Finite Field Identification" section of:
https://www.itu.int/ITU-T/formal-language/itu-t/x/x894/2018-cor1/ANSI-X9-62.html
The OpenSSL GF(2^m) code supports only the trinomial and pentanomial
basis X9.62 forms.
This commit updates BN_GF2m_poly2arr() to return `0` (failure) when
the constant term is zero (i.e. the input bitmask BIGNUM is not odd).
Additionally, the return value is made unambiguous when there is not
enough space to also pad the array with a final `-1` sentinel value.
The return value is now always the number of elements (including the
final `-1`) that would be filled when the output array is sufficiently
large. Previously the same count was returned both when the array has
just enough room for the final `-1` and when it had only enough space
for non-sentinel values.
Finally, BN_GF2m_poly2arr() is updated to reject polynomials whose
degree exceeds `OPENSSL_ECC_MAX_FIELD_BITS`, this guards against
CPU exhausition attacks via excessively large inputs.
The above issues do not arise in processing X.509 certificates. These
generally have EC keys from "named curves", and RFC5840 (Section 2.1.1)
disallows explicit EC parameters. The TLS code in OpenSSL enforces this
constraint only after the certificate is decoded, but, even if explicit
parameters are specified, they are in X9.62 form, which cannot represent
problem values as noted above.
Initially reported as oss-fuzz issue 71623.
A closely related issue was earlier reported in
<https://github.com/openssl/openssl/issues/19826>.

The 3.1 FIPS provider no longer writes out the 'status indicator' by
default due to changes related to FIPS 140-3 requirements. For Backwards
compatability if the fipsinstall detects it is loading a 3.0.X FIPS
provider then it will save the 'status indicator' by default.
Disclaimer: Using a fipsinstall command line utility that is not supplied
with the FIPS provider tarball source is not recommended.
This PR deliberately does not attempt to exclude any additional options
that were added after 3.0.X. These additional options will be ignored by older
providers.

If SRP_user_pwd_set1_ids() fails during one of the duplications, or id
is NULL, then the old pointer values are still stored but they are now dangling.
Later when SRP_user_pwd_free() is called these are freed again,
leading to a double free.
Although there are no such uses in OpenSSL as far as I found,
it's still a public API.

fix https://github.com/openssl/openssl/issues/25112
As defined in the C standard:
In all cases the argument is an int, the value of which shall
be representable as an unsigned char or shall equal the value
of the macro EOF. If the argument has any other value, the
behavior is undefined.
This is because they're designed to work with the int values returned
by getc or fgetc; they need extra work to handle a char value.
If EOF is -1 (as it almost always is), with 8-bit bytes, the allowed
inputs to the ctype.h functions are:
{-1, 0, 1, 2, 3, ..., 255}.
However, on platforms where char is signed, such as x86 with the
usual ABI, code like
char *p = ...;
... isspace(*p) ...
may pass in values in the range:
{-128, -127, -126, ..., -2, -1, 0, 1, ..., 127}.
This has two problems:
1. Inputs in the set {-128, -127, -126, ..., -2} are forbidden.
2. The non-EOF byte 0xff is conflated with the value EOF = -1, so
even though the input is not forbidden, it may give the wrong
answer.
Casting char inputs to unsigned char first works around this, by
mapping the (non-EOF character) range {-128, -127, ..., -1} to {128,
129, ..., 255}, leaving no collisions with EOF. So the above
fragment needs to be:
char *p = ...;
... isspace((unsigned char)*p) ...
This patch inserts unsigned char casts where necessary. Most of the
cases I changed, I compile-tested using -Wchar-subscripts -Werror on
NetBSD, which defines the ctype.h functions as macros so that they
trigger the warning when the argument has type char. The exceptions
are under #ifdef __VMS or #ifdef _WIN32. I left alone calls where
the input is int where the cast would obviously be wrong; and I left
alone calls where the input is already unsigned char so the cast is
unnecessary.
