4 years agoDeprecate RAND_pseudo_bytes
Matt Caswell [Thu, 26 Feb 2015 13:52:30 +0000 (13:52 +0000)]
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.

effect of buffering the message for subsequent retransmission if required.
By adding the ticket length after the call to ssl_set_handshake_header the

CRYPTO_128_unwrap(): Fix refactoring damage

crypto/modes/wrap128.c was heavily refactored to support AES Key Wrap
with Padding, and four bugs were introduced into CRYPTO_128_unwrap() at
that time:

- 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.

    size_limit = (((BN_ULONG)1) << bits) - BN_get_word(rnd) - 1;

There is a problem though if bits == BN_BITS2. Shifting by that much causes
undefined behaviour. I did some tests. On my system BN_BITS2 == 64. So I
set bits to 64 and calculated the result of:

I was expecting to get the result 0. I actually got 1! Strangely this...

    (((BN_ULONG)0) << BN_BITS2)

...does equal 0! This means that, on my system at least, size_limit will be
