OpenSSL CHANGES
_______________
- Changes between 1.0.2 and 1.1.0 [xx XXX xxxx]
+ Changes between 1.0.2e and 1.1.0 [xx XXX xxxx]
- *) RAND_pseudo_bytes has been deprecated. Users should use RAND bytes instead.
+ *) Support for ChaCha20 and Poly1305 added to libcrypto and libssl.
+ [Andy Polyakov]
+
+ *) New EC_KEY_METHOD, this replaces the older ECDSA_METHOD and ECDH_METHOD
+ and integrates ECDSA and ECDH functionality into EC. Implementations can
+ now redirect key generation and no longer need to convert to or from
+ ECDSA_SIG format.
+
+ Note: the ecdsa.h and ecdh.h headers are now no longer needed and just
+ include the ec.h header file instead.
+ [Steve Henson]
+
+ *) Remove support for all 40 and 56 bit ciphers. This includes all the export
+ ciphers who are no longer supported and drops support the ephemeral RSA key
+ exchange. The LOW ciphers currently doesn't have any ciphers in it.
+ [Kurt Roeckx]
+
+ *) Make EVP_MD_CTX, EVP_MD and HMAC_CTX opaque. For HMAC_CTX, the
+ following constructors and destructors were added:
+
+ HMAC_CTX *HMAC_CTX_new(void);
+ void HMAC_CTX_free(HMAC_CTX *ctx);
+
+ For EVP_MD, a complete API to create, fill and destroy such
+ methods has been added. See EVP_MD_meth_new(3) for
+ documentation.
+
+ Additional changes:
+ 1) HMAC_CTX_cleanup() and EVP_MD_CTX_cleanup() were removed,
+ HMAC_CTX_init() and EVP_MD_CTX_init() should be called instead
+ to reinitialise and already created structure. Also,
+ HMAC_CTX_init() and EVP_MD_CTX_init() now return 0 for failure
+ and 1 for success (they previously had the return type void).
+ 2) For consistency with the majority of our object creators and
+ destructors, EVP_MD_CTX_(create|destroy) were renamed to
+ EVP_MD_CTX_(new|free). The old names are retained as macros
+ for deprecated builds.
+ [Richard Levitte]
+
+ *) Added ASYNC support. Libcrypto now includes the async sub-library to enable
+ cryptographic operations to be performed asynchronously as long as an
+ asynchronous capable engine is used. See the ASYNC_start_job() man page for
+ further details. Libssl has also had this capability integrated with the
+ introduction of the new mode SSL_MODE_ASYNC and associated error
+ SSL_ERROR_WANT_ASYNC. See the SSL_CTX_set_mode() and SSL_get_error() man
+ pages. This work was developed in partnership with Intel Corp.
+ [Matt Caswell]
+
+ *) SSL_{CTX_}set_ecdh_auto() has been removed and ECDH is support is
+ always enabled now. If you want to disable the support you should
+ exclude it using the list of supported ciphers. This also means that the
+ "-no_ecdhe" option has been removed from s_server.
+ [Kurt Roeckx]
+
+ *) SSL_{CTX}_set_tmp_ecdh() which can set 1 EC curve now internally calls
+ SSL_{CTX_}set1_curves() which can set a list.
+ [Kurt Roeckx]
+
+ *) Remove support for SSL_{CTX_}set_tmp_ecdh_callback(). You should set the
+ curve you want to support using SSL_{CTX_}set1_curves().
+ [Kurt Roeckx]
+
+ *) State machine rewrite. The state machine code has been significantly
+ refactored in order to remove much duplication of code and solve issues
+ with the old code (see ssl/statem/README for further details). This change
+ does have some associated API changes. Notably the SSL_state() function
+ has been removed and replaced by SSL_get_state which now returns an
+ "OSSL_HANDSHAKE_STATE" instead of an int. SSL_set_state() has been removed
+ altogether. The previous handshake states defined in ssl.h and ssl3.h have
+ also been removed.
+ [Matt Caswell]
+
+ *) All instances of the string "ssleay" in the public API were replaced
+ with OpenSSL (case-matching; e.g., OPENSSL_VERSION for #define's)
+ Some error codes related to internal RSA_eay API's were renamed.
+ [Rich Salz]
+
+ *) The demo files in crypto/threads were moved to demo/threads.
+ [Rich Salz]
+
+ *) Removed obsolete engines: 4758cca, aep, atalla, cswift, nuron and sureware.
+ [Matt Caswell]
+
+ *) New ASN.1 embed macro.
+
+ New ASN.1 macro ASN1_EMBED. This is the same as ASN1_SIMPLE except the
+ structure is not allocated: it is part of the parent. That is instead of
+
+ FOO *x;
+
+ it must be:
+
+ FOO x;
+
+ This reduces memory fragmentation and make it impossible to accidentally
+ set a mandatory field to NULL.
+
+ This currently only works for some fields specifically a SEQUENCE, CHOICE,
+ or ASN1_STRING type which is part of a parent SEQUENCE. Since it is
+ equivalent to ASN1_SIMPLE it cannot be tagged, OPTIONAL, SET OF or
+ SEQUENCE OF.
+ [Steve Henson]
+
+ *) Remove EVP_CHECK_DES_KEY, a compile-time option that never compiled.
+ [Emilia Käsper]
+
+ *) Removed DES and RC4 ciphersuites from DEFAULT. Also removed RC2 although
+ in 1.0.2 EXPORT was already removed and the only RC2 ciphersuite is also
+ an EXPORT one. COMPLEMENTOFDEFAULT has been updated accordingly to add
+ DES and RC4 ciphersuites.
+ [Matt Caswell]
+
+ *) Rewrite EVP_DecodeUpdate (base64 decoding) to fix several bugs.
+ This changes the decoding behaviour for some invalid messages,
+ though the change is mostly in the more lenient direction, and
+ legacy behaviour is preserved as much as possible.
+ [Emilia Käsper]
+
+ *) Fix no-stdio build.
+ [ David Woodhouse <David.Woodhouse@intel.com> and also
+ Ivan Nestlerode <ivan.nestlerode@sonos.com> ]
+
+ *) New testing framework
+ The testing framework has been largely rewritten and is now using
+ perl and the perl modules Test::Harness and an extended variant of
+ Test::More called OpenSSL::Test to do its work. All test scripts in
+ test/ have been rewritten into test recipes, and all direct calls to
+ executables in test/Makefile have become individual recipes using the
+ simplified testing OpenSSL::Test::Simple.
+
+ For documentation on our testing modules, do:
+
+ perldoc test/testlib/OpenSSL/Test/Simple.pm
+ perldoc test/testlib/OpenSSL/Test.pm
+
+ [Richard Levitte]
+
+ *) 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.
+
+ *) Documented all exdata functions. Added CRYPTO_free_ex_index.
+ Added a test.
+ [Rich Salz]
+
+ *) Added HTTP GET support to the ocsp command.
+ [Rich Salz]
+
+ *) Changed default digest for the dgst and enc commands from MD5 to
+ sha256
+ [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
*) 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

+
*) Experimental support for a new, fast, unbiased prime candidate generator,
bn_probable_prime_dh_coprime(). Not currently used by any prime generator.

[mancha <mancha1@zoho.com>]
*) Fix some double frees. These are not thought to be exploitable.
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.

[Steve Henson]
- Changes between 1.0.2 and 1.0.2a [xx XXX xxxx]
+ Changes between 1.0.2d and 1.0.2e [3 Dec 2015]
+
+ *) BN_mod_exp may produce incorrect results on x86_64
+
+ There is a carry propagating bug in the x86_64 Montgomery squaring
+ procedure. No EC algorithms are affected. Analysis suggests that attacks
+ against RSA and DSA as a result of this defect would be very difficult to
+ perform and are not believed likely. Attacks against DH are considered just
+ feasible (although very difficult) because most of the work necessary to
+ deduce information about a private key may be performed offline. The amount
+ of resources required for such an attack would be very significant and
+ likely only accessible to a limited number of attackers. An attacker would
+ additionally need online access to an unpatched system using the target
+ private key in a scenario with persistent DH parameters and a private
+ key that is shared between multiple clients. For example this can occur by
+ default in OpenSSL DHE based SSL/TLS ciphersuites.
+
+ This issue was reported to OpenSSL by Hanno Böck.
+ (CVE-2015-3193)
+ [Andy Polyakov]
+
+ *) Certificate verify crash with missing PSS parameter
+
+ The signature verification routines will crash with a NULL pointer
+ dereference if presented with an ASN.1 signature using the RSA PSS
+ algorithm and absent mask generation function parameter. Since these
+ routines are used to verify certificate signature algorithms this can be
+ used to crash any certificate verification operation and exploited in a
+ DoS attack. Any application which performs certificate verification is
+ vulnerable including OpenSSL clients and servers which enable client
+ authentication.
+
+ This issue was reported to OpenSSL by Loïc Jonas Etienne (Qnective AG).
+ (CVE-2015-3194)
+ [Stephen Henson]
+
+ *) X509_ATTRIBUTE memory leak
+
+ When presented with a malformed X509_ATTRIBUTE structure OpenSSL will leak
+ memory. This structure is used by the PKCS#7 and CMS routines so any
+ application which reads PKCS#7 or CMS data from untrusted sources is
+ affected. SSL/TLS is not affected.
+
+ This issue was reported to OpenSSL by Adam Langley (Google/BoringSSL) using
+ libFuzzer.
+ (CVE-2015-3195)
+ [Stephen Henson]
+
+ *) Rewrite EVP_DecodeUpdate (base64 decoding) to fix several bugs.
+ This changes the decoding behaviour for some invalid messages,
+ though the change is mostly in the more lenient direction, and
+ legacy behaviour is preserved as much as possible.
+ [Emilia Käsper]
+
+ *) In DSA_generate_parameters_ex, if the provided seed is too short,
+ return an error
+ [Rich Salz and Ismo Puustinen <ismo.puustinen@intel.com>]
+
+ Changes between 1.0.2c and 1.0.2d [9 Jul 2015]
+
+ *) Alternate chains certificate forgery
+
+ During certificate verfification, OpenSSL will attempt to find an
+ alternative certificate chain if the first attempt to build such a chain
+ fails. An error in the implementation of this logic can mean that an
+ attacker could cause certain checks on untrusted certificates to be
+ bypassed, such as the CA flag, enabling them to use a valid leaf
+ certificate to act as a CA and "issue" an invalid certificate.
+
+ This issue was reported to OpenSSL by Adam Langley/David Benjamin
+ (Google/BoringSSL).
+ [Matt Caswell]
+
+ Changes between 1.0.2b and 1.0.2c [12 Jun 2015]
+
+ *) Fix HMAC ABI incompatibility. The previous version introduced an ABI
+ incompatibility in the handling of HMAC. The previous ABI has now been
+ restored.
+ [Matt Caswell]
+
+ Changes between 1.0.2a and 1.0.2b [11 Jun 2015]
+
+ *) Malformed ECParameters causes infinite loop
+
+ When processing an ECParameters structure OpenSSL enters an infinite loop
+ if the curve specified is over a specially malformed binary polynomial
+ field.
+
+ This can be used to perform denial of service against any
+ system which processes public keys, certificate requests or
+ certificates. This includes TLS clients and TLS servers with
+ client authentication enabled.
+
+ This issue was reported to OpenSSL by Joseph Barr-Pixton.
+ (CVE-2015-1788)
+ [Andy Polyakov]
+
+ *) Exploitable out-of-bounds read in X509_cmp_time
+
+ X509_cmp_time does not properly check the length of the ASN1_TIME
+ string and can read a few bytes out of bounds. In addition,
+ X509_cmp_time accepts an arbitrary number of fractional seconds in the
+ time string.
+
+ An attacker can use this to craft malformed certificates and CRLs of
+ various sizes and potentially cause a segmentation fault, resulting in
+ a DoS on applications that verify certificates or CRLs. TLS clients
+ that verify CRLs are affected. TLS clients and servers with client
+ authentication enabled may be affected if they use custom verification
+ callbacks.
+
+ This issue was reported to OpenSSL by Robert Swiecki (Google), and
+ independently by Hanno Böck.
+ (CVE-2015-1789)
+ [Emilia Käsper]
+
+ *) PKCS7 crash with missing EnvelopedContent
+
+ The PKCS#7 parsing code does not handle missing inner EncryptedContent
+ correctly. An attacker can craft malformed ASN.1-encoded PKCS#7 blobs
+ with missing content and trigger a NULL pointer dereference on parsing.
+
+ Applications that decrypt PKCS#7 data or otherwise parse PKCS#7
+ structures from untrusted sources are affected. OpenSSL clients and
+ servers are not affected.
+
+ This issue was reported to OpenSSL by Michal Zalewski (Google).
+ (CVE-2015-1790)
+ [Emilia Käsper]
+
+ *) CMS verify infinite loop with unknown hash function
+
+ When verifying a signedData message the CMS code can enter an infinite loop
+ if presented with an unknown hash function OID. This can be used to perform
+ denial of service against any system which verifies signedData messages using
+ the CMS code.
+ This issue was reported to OpenSSL by Johannes Bauer.
+ (CVE-2015-1792)
+ [Stephen Henson]
+
+ *) Race condition handling NewSessionTicket
+
+ If a NewSessionTicket is received by a multi-threaded client when attempting to
+ reuse a previous ticket then a race condition can occur potentially leading to
+ a double free of the ticket data.
+ (CVE-2015-1791)
+ [Matt Caswell]
+
+ *) Only support 256-bit or stronger elliptic curves with the
+ 'ecdh_auto' setting (server) or by default (client). Of supported
+ curves, prefer P-256 (both).
+ [Emilia Kasper]

*) Fix so PRNG is seeded in req if using an already existing
DSA key.
[Steve Henson]
*) Eliminate non-ANSI declarations in crypto.h and stack.h.

*) Shared library support for HPUX (in shlib/).
[Lutz Jaenicke <Lutz.Jaenicke@aet.TU-Cottbus.DE> and Anonymous]
*) BN_mul bugfix: In bn_mul_part_recursion() only the a>a[n] && b>b[n]
case was implemented. This caused BN_div_recp() to fail occasionally.
- [Ulf Möller]

RAND_egd() and RAND_status(). In the command line application,
the EGD socket can be specified like a seed file using RANDFILE
or -rand.
- [Ulf Möller]
+ [Ulf Möller]
*) Allow the string CERTIFICATE to be tolerated in PKCS#7 structures.
Some CAs (e.g. Verisign) distribute certificates in this form.
#define OPENSSL_ALGORITHM_DEFINES
#include <openssl/opensslconf.h>

*) ./config recognizes MacOS X now.
[Andy Polyakov]
*) Bug fix for BN_div() when the first words of num and divsor are
equal (it gave wrong results if (rem=(n1-q*d0)&BN_MASK2) < d0).
- [Ulf Möller]
+ [Ulf Möller]
*) Add support for various broken PKCS#8 formats, and command line
options to produce them.
*) New functions BN_CTX_start(), BN_CTX_get() and BT_CTX_end() to
get temporary BIGNUMs from a BN_CTX.

+ [Ulf Möller]
*) Clean up BN_mod_mul_montgomery(): replace the broken (and unreadable)
bignum version of BN_from_montgomery() with the working code from
SSLeay 0.9.0 (the word based version is faster anyway), and clean up
the comments.
- [Ulf Möller]
+ [Ulf Möller]
*) Avoid a race condition in s2_clnt.c (function get_server_hello) that
made it impossible to use the same SSL_SESSION data structure in
*) The return value of RAND_load_file() no longer counts bytes obtained
by stat(). RAND_load_file(..., -1) is new and uses the complete file
to seed the PRNG (previously an explicit byte count was required).
- [Ulf Möller, Bodo Möller]

[Steve Henson]
*) Make BN_generate_prime() return NULL on error if ret!=NULL.
- [Ulf Möller]
+ [Ulf Möller]
*) Retain source code compatibility for BN_prime_checks macro:
BN_is_prime(..., BN_prime_checks, ...) now uses
BN_prime_checks_for_size to determine the appropriate number of
Rabin-Miller iterations.
- [Ulf Möller]
+ [Ulf Möller]
*) Diffie-Hellman uses "safe" primes: DH_check() return code renamed to
DH_CHECK_P_NOT_SAFE_PRIME.
(Check if this is true? OpenPGP calls them "strong".)
- [Ulf Möller]
+ [Ulf Möller]
*) 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
*) Add missing #ifndefs that caused missing symbols when building libssl
as a shared library without RSA. Use #ifndef NO_SSL2 instead of
NO_RSA in ssl/s2*.c.

+ [Kris Kennaway <kris@hub.freebsd.org>, modified by Ulf Möller]
*) 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).
- [Ulf Möller]
+ [Ulf Möller]
