Changes between 1.0.1 and 1.1.0 [xx XXX xxxx]
- *) Add GCM support to TLS library. Some custom code is needed to split
- the IV between the fixed (from PRF) and explicit (from TLS record)
- portions. This adds all GCM ciphersuites supported by RFC5288 and
- RFC5289. Generalise some AES* cipherstrings to inlclude GCM and
- add a special AESGCM string for GCM only.
+ *) Support for automatic EC temporary key parameter selection. If enabled
+ the most preferred EC parameters are automatically used instead of
+ hardcoded fixed parameters. Now a server just has to call:
+ SSL_CTX_set_ecdh_auto(ctx, 1) and the server will automatically
+ support ECDH and use the most appropriate parameters.
[Steve Henson]
- *) Expand range of ctrls for AES GCM. Permit setting invocation
- field on decrypt and retrieval of invocation field only on encrypt.
+ *) Enhance and tidy EC curve and point format TLS extension code. Use
+ static structures instead of allocation if default values are used.
+ New ctrls to set curves we wish to support and to retrieve shared curves.
+ Print out shared curves in s_server. New options to s_server and s_client
+ to set list of supported curves.
[Steve Henson]
- *) Add HMAC ECC ciphersuites from RFC5289. Include SHA384 PRF support.
- As required by RFC5289 these ciphersuites cannot be used if for
- versions of TLS earlier than 1.2.
+ *) New ctrls to retrieve supported signature algorithms and
+ supported curve values as an array of NIDs. Extend openssl utility
+ to print out received values.
+ [Steve Henson]
+
+ *) Add new APIs EC_curve_nist2nid and EC_curve_nid2nist which convert
+ between NIDs and the more common NIST names such as "P-256". Enhance
+ ecparam utility and ECC method to recognise the NIST names for curves.
+ [Steve Henson]
+
+ *) Enhance SSL/TLS certificate chain handling to support different
+ chains for each certificate instead of one chain in the parent SSL_CTX.
+ [Steve Henson]
+
+ *) Support for fixed DH ciphersuite client authentication: where both
+ server and client use DH certificates with common parameters.
+ [Steve Henson]
+
+ *) Support for fixed DH ciphersuites: those requiring DH server
+ certificates.
+ [Steve Henson]
+
+ *) Transparently support X9.42 DH parameters when calling
+ PEM_read_bio_DHparameters. This means existing applications can handle
+ the new parameter format automatically.
+ [Steve Henson]
+
+ *) Initial experimental support for X9.42 DH parameter format: mainly
+ to support use of 'q' parameter for RFC5114 parameters.
+ [Steve Henson]
+
+ *) Add DH parameters from RFC5114 including test data to dhtest.
+ [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 incorporaing 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()
security.
[Emilia Käsper <emilia.kasper@esat.kuleuven.be> (Google)]
+ *) New function OPENSSL_gmtime_diff to find the difference in days
+ and seconds between two tm structures. This will be used to provide
+ additional functionality for ASN1_TIME.
+ [Steve Henson]
+
+ *) Add -trusted_first option which attempts to find certificates in the
+ trusted store even if an untrusted chain is also supplied.
+ [Steve Henson]
+
+ *) Initial experimental support for explicitly trusted non-root CAs.
+ OpenSSL still tries to build a complete chain to a root but if an
+ intermediate CA has a trust setting included that is used. The first
+ setting is used: whether to trust or reject.
+ [Steve Henson]
+
+ *) 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 regnegotiation 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.
+ [Steve Henson]
+
+ Changes between 1.0.1 and 1.0.1a [xx XXX xxxx]
+
+ *) Fix SEGV in Vector Permutation AES module observed in OpenSSH.
+ [Andy Polyakov]
+
+ Changes between 1.0.0h and 1.0.1 [14 Mar 2012]
+
+ *) Add compatibility with old MDC2 signatures which use an ASN1 OCTET
+ STRING form instead of a DigestInfo.
+ [Steve Henson]
+
+ *) The format used for MDC2 RSA signatures is inconsistent between EVP
+ and the RSA_sign/RSA_verify functions. This was made more apparent when
+ OpenSSL used RSA_sign/RSA_verify for some RSA signatures in particular
+ those which went through EVP_PKEY_METHOD in 1.0.0 and later. Detect
+ the correct format in RSA_verify so both forms transparently work.
+ [Steve Henson]
+
+ *) Add compatibility with old MDC2 signatures which use an ASN1 OCTET
+ STRING form instead of a DigestInfo.
+ [Steve Henson]
+
+ *) Some servers which support TLS 1.0 can choke if we initially indicate
+ support for TLS 1.2 and later renegotiate using TLS 1.0 in the RSA
+ encrypted premaster secret. As a workaround use the maximum pemitted
+ client version in client hello, this should keep such servers happy
+ and still work with previous versions of OpenSSL.
+ [Steve Henson]
+
+ *) Add support for TLS/DTLS heartbeats.
+ [Robin Seggelmann <seggelmann@fh-muenster.de>]
+
+ *) Add support for SCTP.
+ [Robin Seggelmann <seggelmann@fh-muenster.de>]
+
+ *) Improved PRNG seeding for VOS.
+ [Paul Green <Paul.Green@stratus.com>]
+
+ *) Extensive assembler packs updates, most notably:
+
+ - x86[_64]: AES-NI, PCLMULQDQ, RDRAND support;
+ - x86[_64]: SSSE3 support (SHA1, vector-permutation AES);
+ - x86_64: bit-sliced AES implementation;
+ - ARM: NEON support, contemporary platforms optimizations;
+ - s390x: z196 support;
+ - *: GHASH and GF(2^m) multiplication implementations;
+
+ [Andy Polyakov]
+
+ *) Make TLS-SRP code conformant with RFC 5054 API cleanup
+ (removal of unnecessary code)
+ [Peter Sylvester <peter.sylvester@edelweb.fr>]
+
+ *) Add TLS key material exporter from RFC 5705.
+ [Eric Rescorla]
+
+ *) Add DTLS-SRTP negotiation from RFC 5764.
+ [Eric Rescorla]
+
*) Add Next Protocol Negotiation,
http://tools.ietf.org/html/draft-agl-tls-nextprotoneg-00. Can be
disabled with a no-npn flag to config or Configure. Code donated
by Google.
[Adam Langley <agl@google.com> and Ben Laurie]
+ *) Add optional 64-bit optimized implementations of elliptic curves NIST-P224,
+ NIST-P256, NIST-P521, with constant-time single point multiplication on
+ typical inputs. Compiler support for the nonstandard type __uint128_t is
+ required to use this (present in gcc 4.4 and later, for 64-bit builds).
+ Code made available under Apache License version 2.0.
+
+ Specify "enable-ec_nistp_64_gcc_128" on the Configure (or config) command
+ line to include this in your build of OpenSSL, and run "make depend" (or
+ "make update"). This enables the following EC_METHODs:
+
+ EC_GFp_nistp224_method()
+ EC_GFp_nistp256_method()
+ EC_GFp_nistp521_method()
+
+ EC_GROUP_new_by_curve_name() will automatically use these (while
+ EC_GROUP_new_curve_GFp() currently prefers the more flexible
+ implementations).
+ [Emilia Käsper, Adam Langley, Bodo Moeller (Google)]
+
*) Use type ossl_ssize_t instad of ssize_t which isn't available on
all platforms. Move ssize_t definition from e_os.h to the public
header file e_os2.h as it now appears in public header file cms.h
[Steve Henson]
- *) New function OPENSSL_gmtime_diff to find the difference in days
- and seconds between two tm structures. This will be used to provide
- additional functionality for ASN1_TIME.
- [Steve Henson]
-
*) New -sigopt option to the ca, req and x509 utilities. Additional
signature parameters can be passed using this option and in
particular PSS.
parameters r, s.
[Steve Henson]
- *) Add -trusted_first option which attempts to find certificates in the
- trusted store even if an untrusted chain is also supplied.
+ *) Password based recipient info support for CMS library: implementing
+ RFC3211.
[Steve Henson]
- *) Initial experimental support for explicitly trusted non-root CAs.
- OpenSSL still tries to build a complete chain to a root but if an
- intermediate CA has a trust setting included that is used. The first
- setting is used: whether to trust or reject.
+ *) Split password based encryption into PBES2 and PBKDF2 functions. This
+ neatly separates the code into cipher and PBE sections and is required
+ for some algorithms that split PBES2 into separate pieces (such as
+ password based CMS).
[Steve Henson]
- *) New -verify_name option in command line utilities to set verification
- parameters by name.
- [Steve Henson]
+ *) Session-handling fixes:
+ - Fix handling of connections that are resuming with a session ID,
+ but also support Session Tickets.
+ - Fix a bug that suppressed issuing of a new ticket if the client
+ presented a ticket with an expired session.
+ - Try to set the ticket lifetime hint to something reasonable.
+ - Make tickets shorter by excluding irrelevant information.
+ - On the client side, don't ignore renewed tickets.
+ [Adam Langley, Bodo Moeller (Google)]
- *) Initial CMAC implementation. WARNING: EXPERIMENTAL, API MAY CHANGE.
- Add CMAC pkey methods.
- [Steve Henson]
+ *) Fix PSK session representation.
+ [Bodo Moeller]
- *) Experiemental regnegotiation in s_server -www mode. If the client
- browses /reneg connection is renegotiated. If /renegcert it is
- renegotiated requesting a certificate.
- [Steve Henson]
+ *) Add RC4-MD5 and AESNI-SHA1 "stitched" implementations.
- *) 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]
+ This work was sponsored by Intel.
+ [Andy Polyakov]
- *) Experiemental password based recipient info support for CMS library:
- implementing RFC3211.
+ *) Add GCM support to TLS library. Some custom code is needed to split
+ the IV between the fixed (from PRF) and explicit (from TLS record)
+ portions. This adds all GCM ciphersuites supported by RFC5288 and

[Steve Henson]

- 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.
+ *) For FIPS capable OpenSSL interpret a NULL default public key method
+ as unset and return the appopriate default but do *not* set the default.
+ This means we can return the appopriate method in applications that
+ swicth between FIPS and non-FIPS modes.
[Steve Henson]
-
- Changes between 1.0.0e and 1.0.1 [xx XXX xxxx]
*) Redirect HMAC and CMAC operations to FIPS module in FIPS mode. If an
ENGINE is used then we cannot handle that in the FIPS module so we
keep original code iff non-FIPS operations are allowed.
[Steve Henson]
- *) Add -attime option to openssl verify.
- [Peter Eckersley <pde@eff.org> and Ben Laurie]
+ *) Add -attime option to openssl utilities.
+ [Peter Eckersley <pde@eff.org>, Ben Laurie and Steve Henson]
*) Redirect DSA and DH operations to FIPS module in FIPS mode.
[Steve Henson]
*) Add functions to copy EVP_PKEY_METHOD and retrieve flags and id.
[Steve Henson]
- *) Add EC_GFp_nistp224_method(), a 64-bit optimized implementation for
- elliptic curve NIST-P224 with constant-time single point multiplication on
- typical inputs. EC_GROUP_new_by_curve_name() will automatically use this
- (while EC_GROUP_new_curve_GFp() currently won't and prefers the more
- flexible implementations).
-
- The implementation requires support for the nonstandard type __uint128_t,
- and so is disabled by default. To include this in your build of OpenSSL,
- use -DEC_NISTP224_64_GCC_128 on the Configure (or config) command line,
- and run "make depend" (or "make update").
- [Emilia Käsper <emilia.kasper@esat.kuleuven.be> (Google)]
-
*) Permit abbreviated handshakes when renegotiating using the function
SSL_renegotiate_abbreviated().
[Robin Seggelmann <seggelmann@fh-muenster.de>]
Add command line options to s_client/s_server.
[Steve Henson]
- Changes between 1.0.0d and 1.0.0e [xx XXX xxxx]
+ Changes between 1.0.0g and 1.0.0h [12 Mar 2012]
+
+ *) Fix MMA (Bleichenbacher's attack on PKCS #1 v1.5 RSA padding) weakness
+ in CMS and PKCS7 code. When RSA decryption fails use a random key for
+ content decryption and always return the same error. Note: this attack
+ needs on average 2^20 messages so it only affects automated senders. The
+ old behaviour can be reenabled in the CMS code by setting the
+ CMS_DEBUG_DECRYPT flag: this is useful for debugging and testing where
+ an MMA defence is not necessary.
+ Thanks to Ivan Nestlerode <inestlerode@us.ibm.com> for discovering
+ this issue. (CVE-2012-0884)
+ [Steve Henson]
+
+ *) Fix CVE-2011-4619: make sure we really are receiving a
+ client hello before rejecting multiple SGC restarts. Thanks to
+ Ivan Nestlerode <inestlerode@us.ibm.com> for discovering this bug.
+ [Steve Henson]
+

+ [Antonio Martin]
+
+ Changes between 1.0.0e and 1.0.0f [4 Jan 2012]
+
+ *) Nadhem Alfardan and Kenny Paterson have discovered an extension
+ of the Vaudenay padding oracle attack on CBC mode encryption
+ which enables an efficient plaintext recovery attack against
+ the OpenSSL implementation of DTLS. Their attack exploits timing
+ differences arising during decryption processing. A research
+ paper describing this attack can be found at:

+ [Emilia Käsper (Google)]
+
+ *) Fix the BIO_f_buffer() implementation (which was mixing different

+ [Adam Langley (Google)]
+
+ *) Fix handling of BN_BLINDING: now BN_BLINDING_invert_ex (rather than
+ BN_BLINDING_invert_ex) calls BN_BLINDING_update, ensuring that concurrent
+ threads won't reuse the same blinding coefficients.
+
+ This also avoids the need to obtain the CRYPTO_LOCK_RSA_BLINDING
+ lock to call BN_BLINDING_invert_ex, and avoids one use of
+ BN_BLINDING_update for each BN_BLINDING structure (previously,
+ the last update always remained unused).
+ [Emilia Käsper (Google)]

+ by initialising X509_STORE_CTX properly. (CVE-2011-3207)
+ [Kaspar Brand <ossl@velox.ch>]
+
+ *) Fix SSL memory handling for (EC)DH ciphersuites, in particular
+ for multi-threaded use of ECDH. (CVE-2011-3210)
+ [Adam Langley (Google)]
+
+ *) Fix x509_name_ex_d2i memory leak on bad inputs.
+ [Bodo Moeller]
+
+ *) Remove hard coded ecdsaWithSHA1 signature tests in ssl code and check
+ signature public key algorithm by using OID xref utilities instead.
+ Before this you could only use some ECC ciphersuites with SHA1 only.
+ [Steve Henson]
*) Add protection against ECDSA timing attacks as mentioned in the paper
by Billy Bob Brumley and Nicola Tuveri, see:
*) Change 'Configure' script to enable Camellia by default.
