OpenSSL CHANGES
_______________
- Changes between 1.0.2c and 1.0.2d [xx XXX xxxx]
+ Changes between 1.0.2d and 1.0.2e [xx XXX xxxx]
+
+ *) In DSA_generate_parameters_ex, if the provided seed is too short,
+ return an error
+ [Rich Salz and Ismo Puustinen <ismo.puustinen@intel.com>]
+
+ *) Rewrite PSK to support ECDHE_PSK, DHE_PSK and RSA_PSK. Add ciphersuites
+ from RFC4279, RFC4785, RFC5487, RFC5489.
+
+ Thanks to Christian J. Dietrich and Giuseppe D'Angelo for the
+ original RSA_PSK patch.
+ [Steve Henson]
+
+ *) Dropped support for the SSL3_FLAGS_DELAY_CLIENT_FINISHED flag. This SSLeay
+ era flag was never set throughout the codebase (only read). Also removed
+ SSL3_FLAGS_POP_BUFFER which was only used if
+ SSL3_FLAGS_DELAY_CLIENT_FINISHED was also set.
+ [Matt Caswell]
+
+ *) Changed the default name options in the "ca", "crl", "req" and "x509"
+ to be "oneline" instead of "compat".
+ [Richard Levitte]
+
+ *) Remove SSL_OP_TLS_BLOCK_PADDING_BUG. This is SSLeay legacy, we're
+ not aware of clients that still exhibit this bug, and the workaround
+ hasn't been working properly for a while.
+ [Emilia Käsper]
+
+ *) The return type of BIO_number_read() and BIO_number_written() as well as
+ the corresponding num_read and num_write members in the BIO structure has
+ changed from unsigned long to uint64_t. On platforms where an unsigned
+ long is 32 bits (e.g. Windows) these counters could overflow if >4Gb is
+ transferred.
+ [Matt Caswell]
+
+ *) Given the pervasive nature of TLS extensions it is inadvisable to run
+ OpenSSL without support for them. It also means that maintaining
+ the OPENSSL_NO_TLSEXT option within the code is very invasive (and probably
+ not well tested). Therefore the OPENSSL_NO_TLSEXT option has been removed.
+ [Matt Caswell]
+
+ *) Removed support for the two export grade static DH ciphersuites
+ EXP-DH-RSA-DES-CBC-SHA and EXP-DH-DSS-DES-CBC-SHA. These two ciphersuites
+ were newly added (along with a number of other static DH ciphersuites) to
+ 1.0.2. However the two export ones have *never* worked since they were
+ introduced. It seems strange in any case to be adding new export
+ ciphersuites, and given "logjam" it also does not seem correct to fix them.
+ [Matt Caswell]
+
+ *) Version negotiation has been rewritten. In particular SSLv23_method(),
+ SSLv23_client_method() and SSLv23_server_method() have been deprecated,
+ and turned into macros which simply call the new preferred function names
+ TLS_method(), TLS_client_method() and TLS_server_method(). All new code
+ should use the new names instead. Also as part of this change the ssl23.h
+ header file has been removed.
+ [Matt Caswell]
+
+ *) Support for Kerberos ciphersuites in TLS (RFC2712) has been removed. This
+ code and the associated standard is no longer considered fit-for-purpose.
+ [Matt Caswell]
+
+ *) RT2547 was closed. When generating a private key, try to make the
+ output file readable only by the owner. This behavior change might
+ be noticeable when interacting with other software.
+
+ *) Added HTTP GET support to the ocsp command.
+ [Rich Salz]
+
+ *) RAND_pseudo_bytes has been deprecated. Users should use RAND_bytes instead.
+ [Matt Caswell]
+
+ *) Added support for TLS extended master secret from
+ draft-ietf-tls-session-hash-03.txt. Thanks for Alfredo Pironti for an
+ initial patch which was a great help during development.
+ [Steve Henson]
+
+ *) All libssl internal structures have been removed from the public header
+ files, and the OPENSSL_NO_SSL_INTERN option has been removed (since it is
+ now redundant). Users should not attempt to access internal structures
+ directly. Instead they should use the provided API functions.
+ [Matt Caswell]
+
+ *) config has been changed so that by default OPENSSL_NO_DEPRECATED is used.
+ Access to deprecated functions can be re-enabled by running config with
+ "enable-deprecated". In addition applications wishing to use deprecated
+ functions must define OPENSSL_USE_DEPRECATED. Note that this new behaviour
+ will, by default, disable some transitive includes that previously existed
+ in the header files (e.g. ec.h will no longer, by default, include bn.h)
+ [Matt Caswell]
+
+ *) Added support for OCB mode. OpenSSL has been granted a patent license
+ compatible with the OpenSSL license for use of OCB. Details are available
+ at https://www.openssl.org/docs/misc/OCB-patent-grant-OpenSSL.pdf. Support
+ for OCB can be removed by calling config with no-ocb.
+ [Matt Caswell]
+
+ *) SSLv2 support has been removed. It still supports receiving a SSLv2
+ compatible client hello.
+ [Kurt Roeckx]
+
+ *) Increased the minimal RSA keysize from 256 to 512 bits [Rich Salz],
+ done while fixing the error code for the key-too-small case.
+ [Annie Yousar <a.yousar@informatik.hu-berlin.de>]
+
+ *) CA.sh has been removmed; use CA.pl instead.
+ [Rich Salz]
+
+ *) Removed old DES API.
+ [Rich Salz]
+
+ *) Remove various unsupported platforms:
+ Sony NEWS4
+ BEOS and BEOS_R5
+ NeXT
+ SUNOS
+ MPE/iX
+ Sinix/ReliantUNIX RM400
+ DGUX
+ NCR
+ Tandem
+ Cray
+ 16-bit platforms such as WIN16
+ [Rich Salz]
+
+ *) Clean up OPENSSL_NO_xxx #define's
+ Use setbuf() and remove OPENSSL_NO_SETVBUF_IONBF
+ Rename OPENSSL_SYSNAME_xxx to OPENSSL_SYS_xxx
+ OPENSSL_NO_EC{DH,DSA} merged into OPENSSL_NO_EC
+ OPENSSL_NO_RIPEMD160, OPENSSL_NO_RIPEMD merged into OPENSSL_NO_RMD160
+ OPENSSL_NO_FP_API merged into OPENSSL_NO_STDIO
+ Remove OPENSSL_NO_BIO OPENSSL_NO_BUFFER OPENSSL_NO_CHAIN_VERIFY
+ OPENSSL_NO_EVP OPENSSL_NO_FIPS_ERR OPENSSL_NO_HASH_COMP
+ OPENSSL_NO_LHASH OPENSSL_NO_OBJECT OPENSSL_NO_SPEED OPENSSL_NO_STACK
+ OPENSSL_NO_X509 OPENSSL_NO_X509_VERIFY
+ Remove MS_STATIC; it's a relic from platforms <32 bits.
+ [Rich Salz]
+
+ *) Cleaned up dead code
+ Remove all but one '#ifdef undef' which is to be looked at.
+ [Rich Salz]
+
+ *) Clean up calling of xxx_free routines.
+ Just like free(), fix most of the xxx_free routines to accept
+ NULL. Remove the non-null checks from callers. Save much code.
+ [Rich Salz]
+
+ *) Add secure heap for storage of private keys (when possible).
+ Add BIO_s_secmem(), CBIGNUM, etc.
+ Contributed by Akamai Technologies under our Corporate CLA.
+ [Rich Salz]
+
+ *) Experimental support for a new, fast, unbiased prime candidate generator,
+ bn_probable_prime_dh_coprime(). Not currently used by any prime generator.
+ [Felix Laurie von Massenbach <felix@erbridge.co.uk>]
+
+ *) New output format NSS in the sess_id command line tool. This allows
+ exporting the session id and the master key in NSS keylog format.
+ [Martin Kaiser <martin@kaiser.cx>]
+
+ *) Harmonize version and its documentation. -f flag is used to display
+ compilation flags.
+ [mancha <mancha1@zoho.com>]
+
+ *) Fix eckey_priv_encode so it immediately returns an error upon a failure
+ in i2d_ECPrivateKey. Thanks to Ted Unangst for feedback on this issue.
+ [mancha <mancha1@zoho.com>]
+
+ *) Fix some double frees. These are not thought to be exploitable.
+ [mancha <mancha1@zoho.com>]
+
+ *) A missing bounds check in the handling of the TLS heartbeat extension
+ can be used to reveal up to 64k of memory to a connected client or
+ server.
+
+ Thanks for Neel Mehta of Google Security for discovering this bug and to
+ Adam Langley <agl@chromium.org> and Bodo Moeller <bmoeller@acm.org> for
+ preparing the fix (CVE-2014-0160)
+ [Adam Langley, Bodo Moeller]
+
+ *) Fix for the attack described in the paper "Recovering OpenSSL
+ ECDSA Nonces Using the FLUSH+RELOAD Cache Side-channel Attack"
+ by Yuval Yarom and Naomi Benger. Details can be obtained from:
+ http://eprint.iacr.org/2014/140
+
+ Thanks to Yuval Yarom and Naomi Benger for discovering this
+ flaw and to Yuval Yarom for supplying a fix (CVE-2014-0076)
+ [Yuval Yarom and Naomi Benger]
+
+ *) Use algorithm specific chains in SSL_CTX_use_certificate_chain_file():
+ this fixes a limitation in previous versions of OpenSSL.
+ [Steve Henson]
+
+ *) Experimental encrypt-then-mac support.
+
+ Experimental support for encrypt then mac from
+ draft-gutmann-tls-encrypt-then-mac-02.txt
+
+ To enable it set the appropriate extension number (0x42 for the test
+ server) using e.g. -DTLSEXT_TYPE_encrypt_then_mac=0x42
+
+ For non-compliant peers (i.e. just about everything) this should have no
+ effect.
+
+ WARNING: EXPERIMENTAL, SUBJECT TO CHANGE.
+
+ [Steve Henson]
+
+ *) Add EVP support for key wrapping algorithms, to avoid problems with
+ existing code the flag EVP_CIPHER_CTX_WRAP_ALLOW has to be set in
+ the EVP_CIPHER_CTX or an error is returned. Add AES and DES3 wrap
+ algorithms and include tests cases.
+ [Steve Henson]
+
+ *) Extend CMS code to support RSA-PSS signatures and RSA-OAEP for
+ enveloped data.
+ [Steve Henson]
+
+ *) Extended RSA OAEP support via EVP_PKEY API. Options to specify digest,
+ MGF1 digest and OAEP label.
+ [Steve Henson]
+
+ *) Make openssl verify return errors.
+ [Chris Palmer <palmer@google.com> and Ben Laurie]
+
+ *) New function ASN1_TIME_diff to calculate the difference between two
+ ASN1_TIME structures or one structure and the current time.
+ [Steve Henson]
+
+ *) Update fips_test_suite to support multiple command line options. New
+ test to induce all self test errors in sequence and check expected
+ failures.
+ [Steve Henson]
+
+ *) Add FIPS_{rsa,dsa,ecdsa}_{sign,verify} functions which digest and
+ sign or verify all in one operation.
+ [Steve Henson]
+
+ *) Add fips_algvs: a multicall fips utility incorporating all the algorithm
+ test programs and fips_test_suite. Includes functionality to parse
+ the minimal script output of fipsalgest.pl directly.
+ [Steve Henson]
+
+ *) Add authorisation parameter to FIPS_module_mode_set().
+ [Steve Henson]
+
+ *) Add FIPS selftest for ECDH algorithm using P-224 and B-233 curves.
+ [Steve Henson]
+
+ *) Use separate DRBG fields for internal and external flags. New function
+ FIPS_drbg_health_check() to perform on demand health checking. Add
+ generation tests to fips_test_suite with reduced health check interval to
+ demonstrate periodic health checking. Add "nodh" option to
+ fips_test_suite to skip very slow DH test.
+ [Steve Henson]
+
+ *) New function FIPS_get_cipherbynid() to lookup FIPS supported ciphers
+ based on NID.
+ [Steve Henson]
+
+ *) More extensive health check for DRBG checking many more failure modes.
+ New function FIPS_selftest_drbg_all() to handle every possible DRBG
+ combination: call this in fips_test_suite.
+ [Steve Henson]
+
+ *) Add support for Dual EC DRBG from SP800-90. Update DRBG algorithm test
+ and POST to handle Dual EC cases.
+ [Steve Henson]
+
+ *) Add support for canonical generation of DSA parameter 'g'. See
+ FIPS 186-3 A.2.3.
+
+ *) Add support for HMAC DRBG from SP800-90. Update DRBG algorithm test and
+ POST to handle HMAC cases.
+ [Steve Henson]
+
+ *) Add functions FIPS_module_version() and FIPS_module_version_text()
+ to return numerical and string versions of the FIPS module number.
+ [Steve Henson]
+
+ *) Rename FIPS_mode_set and FIPS_mode to FIPS_module_mode_set and
+ FIPS_module_mode. FIPS_mode and FIPS_mode_set will be implemented
+ outside the validated module in the FIPS capable OpenSSL.
+ [Steve Henson]
+
+ *) Minor change to DRBG entropy callback semantics. In some cases
+ there is no multiple of the block length between min_len and
+ max_len. Allow the callback to return more than max_len bytes
+ of entropy but discard any extra: it is the callback's responsibility
+ to ensure that the extra data discarded does not impact the
+ requested amount of entropy.
+ [Steve Henson]
+
+ *) Add PRNG security strength checks to RSA, DSA and ECDSA using
+ information in FIPS186-3, SP800-57 and SP800-131A.
+ [Steve Henson]
+
+ *) CCM support via EVP. Interface is very similar to GCM case except we
+ must supply all data in one chunk (i.e. no update, final) and the
+ message length must be supplied if AAD is used. Add algorithm test
+ support.
+ [Steve Henson]
+
+ *) Initial version of POST overhaul. Add POST callback to allow the status
+ of POST to be monitored and/or failures induced. Modify fips_test_suite
+ to use callback. Always run all selftests even if one fails.
+ [Steve Henson]
+
+ *) XTS support including algorithm test driver in the fips_gcmtest program.
+ Note: this does increase the maximum key length from 32 to 64 bytes but
+ there should be no binary compatibility issues as existing applications
+ will never use XTS mode.
+ [Steve Henson]
+
+ *) Extensive reorganisation of FIPS PRNG behaviour. Remove all dependencies
+ to OpenSSL RAND code and replace with a tiny FIPS RAND API which also
+ performs algorithm blocking for unapproved PRNG types. Also do not
+ set PRNG type in FIPS_mode_set(): leave this to the application.
+ Add default OpenSSL DRBG handling: sets up FIPS PRNG and seeds with
+ the standard OpenSSL PRNG: set additional data to a date time vector.
+ [Steve Henson]
+
+ *) Rename old X9.31 PRNG functions of the form FIPS_rand* to FIPS_x931*.
+ This shouldn't present any incompatibility problems because applications
+ shouldn't be using these directly and any that are will need to rethink
+ anyway as the X9.31 PRNG is now deprecated by FIPS 140-2
+ [Steve Henson]
+
+ *) Extensive self tests and health checking required by SP800-90 DRBG.
+ Remove strength parameter from FIPS_drbg_instantiate and always
+ instantiate at maximum supported strength.
+ [Steve Henson]
+
+ *) Add ECDH code to fips module and fips_ecdhvs for primitives only testing.
+ [Steve Henson]
+
+ *) New algorithm test program fips_dhvs to handle DH primitives only testing.
+ [Steve Henson]
+
+ *) New function DH_compute_key_padded() to compute a DH key and pad with
+ leading zeroes if needed: this complies with SP800-56A et al.
+ [Steve Henson]
+
+ *) Initial implementation of SP800-90 DRBGs for Hash and CTR. Not used by
+ anything, incomplete, subject to change and largely untested at present.
+ [Steve Henson]
+
+ *) Modify fipscanisteronly build option to only build the necessary object
+ files by filtering FIPS_EX_OBJ through a perl script in crypto/Makefile.
+ [Steve Henson]
+
+ *) Add experimental option FIPSSYMS to give all symbols in
+ fipscanister.o and FIPS or fips prefix. This will avoid
+ conflicts with future versions of OpenSSL. Add perl script
+ util/fipsas.pl to preprocess assembly language source files
+ and rename any affected symbols.
+ [Steve Henson]
+
+ *) Add selftest checks and algorithm block of non-fips algorithms in
+ FIPS mode. Remove DES2 from selftests.
+ [Steve Henson]
+
+ *) Add ECDSA code to fips module. Add tiny fips_ecdsa_check to just
+ return internal method without any ENGINE dependencies. Add new
+ tiny fips sign and verify functions.
+ [Steve Henson]
+
+ *) New build option no-ec2m to disable characteristic 2 code.
+ [Steve Henson]
+
+ *) New build option "fipscanisteronly". This only builds fipscanister.o
+ and (currently) associated fips utilities. Uses the file Makefile.fips
+ instead of Makefile.org as the prototype.
+ [Steve Henson]
+
+ *) Add some FIPS mode restrictions to GCM. Add internal IV generator.
+ Update fips_gcmtest to use IV generator.
+ [Steve Henson]
+
+ *) Initial, experimental EVP support for AES-GCM. AAD can be input by
+ setting output buffer to NULL. The *Final function must be
+ called although it will not retrieve any additional data. The tag
+ can be set or retrieved with a ctrl. The IV length is by default 12
+ bytes (96 bits) but can be set to an alternative value. If the IV
+ length exceeds the maximum IV length (currently 16 bytes) it cannot be
+ set before the key.
+ [Steve Henson]
+
+ *) New flag in ciphers: EVP_CIPH_FLAG_CUSTOM_CIPHER. This means the
+ underlying do_cipher function handles all cipher semantics itself
+ including padding and finalisation. This is useful if (for example)
+ an ENGINE cipher handles block padding itself. The behaviour of
+ do_cipher is subtly changed if this flag is set: the return value
+ is the number of characters written to the output buffer (zero is
+ no longer an error code) or a negative error code. Also if the
+ input buffer is NULL and length 0 finalisation should be performed.
+ [Steve Henson]
+
+ *) If a candidate issuer certificate is already part of the constructed
+ path ignore it: new debug notification X509_V_ERR_PATH_LOOP for this case.
+ [Steve Henson]
+
+ *) Improve forward-security support: add functions
+
+ void SSL_CTX_set_not_resumable_session_callback(SSL_CTX *ctx, int (*cb)(SSL *ssl, int is_forward_secure))
+ void SSL_set_not_resumable_session_callback(SSL *ssl, int (*cb)(SSL *ssl, int is_forward_secure))
+
+ for use by SSL/TLS servers; the callback function will be called whenever a
+ new session is created, and gets to decide whether the session may be
+ cached to make it resumable (return 0) or not (return 1). (As by the
+ SSL/TLS protocol specifications, the session_id sent by the server will be
+ empty to indicate that the session is not resumable; also, the server will
+ not generate RFC 4507 (RFC 5077) session tickets.)
+
+ A simple reasonable callback implementation is to return is_forward_secure.
+ This parameter will be set to 1 or 0 depending on the ciphersuite selected
+ by the SSL/TLS server library, indicating whether it can provide forward
+ security.
+ [Emilia Käsper <emilia.kasper@esat.kuleuven.be> (Google)]
+
+ *) New -verify_name option in command line utilities to set verification
+ parameters by name.
+ [Steve Henson]
+
+ *) Initial CMAC implementation. WARNING: EXPERIMENTAL, API MAY CHANGE.
+ Add CMAC pkey methods.
+ [Steve Henson]
+
+ *) Experimental renegotiation in s_server -www mode. If the client
+ browses /reneg connection is renegotiated. If /renegcert it is
+ renegotiated requesting a certificate.
+ [Steve Henson]
+
+ *) Add an "external" session cache for debugging purposes to s_server. This
+ should help trace issues which normally are only apparent in deployed
+ multi-process servers.
+ [Steve Henson]
+
+ *) Extensive audit of libcrypto with DEBUG_UNUSED. Fix many cases where
+ return value is ignored. NB. The functions RAND_add(), RAND_seed(),
+ BIO_set_cipher() and some obscure PEM functions were changed so they
+ can now return an error. The RAND changes required a change to the
+ RAND_METHOD structure.
+ [Steve Henson]
+
+ *) New macro __owur for "OpenSSL Warn Unused Result". This makes use of
+ a gcc attribute to warn if the result of a function is ignored. This
+ is enable if DEBUG_UNUSED is set. Add to several functions in evp.h
+ whose return value is often ignored.

made it impossible to use the same SSL_SESSION data structure in
*) The return value of RAND_load_file() no longer counts bytes obtained

BN_is_prime(..., BN_prime_checks, ...) now uses
BN_prime_checks_for_size to determine the appropriate number of
Rabin-Miller iterations.

*) Merge the functionality of "dh" and "gendh" programs into a new program
"dhparam". The old programs are retained for now but will handle DH keys

*) Precautions against using the PRNG uninitialized: RAND_bytes() now
has a return value which indicates the quality of the random data
guaranteed to be unique but not unpredictable. RAND_add is like
RAND_seed, but takes an extra argument for an entropy estimate
(RAND_seed always assumes full entropy).
