implementations:

Other EVP APIs pass the EVP API context down to implementations, and
it can be observed that the implementations use the pointer to their
own private data almost exclusively.  The EVP_MAC API deviates from
that pattern by passing the pointer to the implementation's private
data directly, and thereby deny the implementations access to the
EVP_MAC context structure.  This change is made to provide a clearer

RAND_add()/RAND_seed(): fix failure on short input or low entropy

Commit 5b4cb385c18a (#7382) introduced a bug which had the effect
that RAND_add()/RAND_seed() failed for buffer sizes less than
32 bytes. The reason was that now the added random data was used
exlusively as entropy source for reseeding. When the random input
was too short or contained not enough entropy, the DRBG failed
without querying the available entropy sources.

This commit makes drbg_add() act smarter: it checks the entropy
requirements explicitely. If the random input fails this check,
it won't be added as entropy input, but only as additional data.
More precisely, the behaviour depends on whether an os entropy
source was configured (which is the default on most os):

- If an os entropy source is avaible then we declare the buffer
  content as additional data by setting randomness to zero and
  trigger a regular   reseeding.

- If no os entropy source is available, a reseeding will fail
  inevitably. So drbg_add() uses a trick to mix the buffer contents
  into the DRBG state without forcing a reseeding: it generates a
  dummy random byte, using the buffer content as additional data.

RAND_add(): fix heap corruption in error path

chunks of 1024 bytes each. If the size of the final chunk is less than
32 bytes, then RAND_add() fails, whence RAND_load_file() fails

   certificate, and is not included in this limit.  Usually, the last
   certificate is an end entity certificate, but it can be a CA
   certificate.)

This makes it clear that exclusion of self-issued certificates from
the path length count applies only to some *intermediate* CA
certificates.  A leaf certificate whether it has identical issuer
and subject or whether it is a CA or not is never part of the
intermediate certificate count.  The handling of all leaf certificates

path count by 1, so that we ultimately reach a non-self-issued

11 months agoDRBG: fix reseeding via RAND_add()/RAND_seed() with large input
Dr. Matthias St. Pierre [Tue, 9 Oct 2018 23:53:29 +0000 (01:53 +0200)]
DRBG: fix reseeding via RAND_add()/RAND_seed() with large input

In pull request #4328 the seeding of the DRBG via RAND_add()/RAND_seed()
was implemented by buffering the data in a random pool where it is
picked up later by the rand_drbg_get_entropy() callback. This buffer
was limited to the size of 4096 bytes.

When a larger input was added via RAND_add() or RAND_seed() to the DRBG,
the reseeding failed, but the error returned by the DRBG was ignored
by the two calling functions, which both don't return an error code.
As a consequence, the data provided by the application was effectively
ignored.

This commit fixes the problem by a more efficient implementation which
does not copy the data in memory and by raising the buffer the size limit
to INT32_MAX (2 gigabytes). This is less than the NIST limit of 2^35 bits
but it was chosen intentionally to avoid platform dependent problems
like integer sizes and/or signed/unsigned conversion.

Additionally, the DRBG is now less permissive on errors: In addition to
pushing a message to the openssl error stack, it enters the error state,
which forces a reinstantiation on next call.

Thanks go to Dr. Falko Strenzke for reporting this issue to the
openssl-security mailing list. After internal discussion the issue
has been categorized as not being security relevant, because the DRBG
reseeds automatically and is fully functional even without additional
randomness provided by the application.

apps: allow empty attribute values with -subj

Historically (i.e., OpenSSL 1.0.x), the openssl applications would
allow for empty subject attributes to be passed via the -subj argument,
e.g., `opensl req -subj '/CN=joe/O=/OU=local' ...`.  Commit
db4c08f0194d58c6192f0d8311bf3f20e251cf4f applied a badly needed rewrite

in the process dropped a check that would skip attributes with no
associated value.  As a result, such strings are now treated as
hard errors and the operation fails.

the historical behavior.
