      RAND_add(): fix heap corruption in error path · ece482ff
      Dr. Matthias St. Pierre 提交于
      This bug was introduced by #7382 which enhanced RAND_add() to
      accept large buffer sizes. As a consequence, RAND_add() now fails
      for buffer sizes less than 32 bytes (i.e. less than 256 bits).
      In addition, rand_drbg_get_entropy() forgets to reset the attached
      drbg->pool in the case of an error, which leads to the heap corruption.
      
      The problem occurred with RAND_load_file(), which reads the file in
      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
      silently for buffer sizes n = k * 1024 + r with r = 1,...,31.
      
      This commit fixes the heap corruption only. The other issues will
      be addressed in a separate pull request.
      
      Thanks to Gisle Vanem for reporting this issue.

      build file templates: have targets for all shared library names · 132fd512
      Richard Levitte 提交于
      We only had targets for the "simple" shared library names (libfoo.so
      and not libfoo.so.x.y on Unix, import library libfoo.lib but not
      libfoo.dll on Windows).  This has created some confusion why it wasn't
      possible to rebuild the less "simple" name directly (just as an
      example, someone who mistook the import library on Windows for a
      static library, removed the DLL and then found it was difficult to
      rebuild directly), so we change the target to include all possible
      names.

      Apply self-imposed path length also to root CAs · a190ea8a
      Viktor Dukhovni 提交于
      Also, some readers of the code find starting the count at 1 for EE
      cert confusing (since RFC5280 counts only non-self-issued intermediate
      CAs, but we also counted the leaf).  Therefore, never count the EE
      cert, and adjust the path length comparison accordinly.  This may
      be more clear to the reader.

      Only CA certificates can be self-issued · bb692394
      Viktor Dukhovni 提交于
      At the bottom of https://tools.ietf.org/html/rfc5280#page-12 and
      top of https://tools.ietf.org/html/rfc5280#page-13 (last paragraph
      of above https://tools.ietf.org/html/rfc5280#section-3.3), we see:
      
         This specification covers two classes of certificates: CA
         certificates and end entity certificates.  CA certificates may be
         further divided into three classes: cross-certificates, self-issued
         certificates, and self-signed certificates.  Cross-certificates are
         CA certificates in which the issuer and subject are different
         entities.  Cross-certificates describe a trust relationship between
         the two CAs.  Self-issued certificates are CA certificates in which
         the issuer and subject are the same entity.  Self-issued certificates
         are generated to support changes in policy or operations.  Self-
         signed certificates are self-issued certificates where the digital
         signature may be verified by the public key bound into the
         certificate.  Self-signed certificates are used to convey a public
         key for use to begin certification paths.  End entity certificates
         are issued to subjects that are not authorized to issue certificates.
      
      that the term "self-issued" is only applicable to CAs, not end-entity
      certificates.  In https://tools.ietf.org/html/rfc5280#section-4.2.1.9
      the description of path length constraints says:
      
         The pathLenConstraint field is meaningful only if the cA boolean is
         asserted and the key usage extension, if present, asserts the
         keyCertSign bit (Section 4.2.1.3).  In this case, it gives the
         maximum number of non-self-issued intermediate certificates that may
         follow this certificate in a valid certification path.  (Note: The
         last certificate in the certification path is not an intermediate
         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
      must be the same, in the case of our code to post-increment the
      path count by 1, so that we ultimately reach a non-self-issued
      intermediate it will be the first one (not zeroth) in the chain
      of intermediates.

      apps: allow empty attribute values with -subj · a7ee1ef6
      Benjamin Kaduk 提交于
      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
      db4c08f0 applied a badly needed rewrite
      to the parse_name() helper function that parses these strings, but
      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.
      
      Restore the check to skip empty attribute values and restore
      the historical behavior.
      
      Document the behavior for empty subject attribute values in the
      corresponding applications' manual pages.
