OpenSSL CHANGES
_______________
- Changes between 1.0.0e and 1.0.1 [xx XXX xxxx]
+ Changes between 1.0.0f and 1.0.1 [xx XXX xxxx]
+
+ *) 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 -sigopt option to the ca, req and x509 utilities. Additional
+ signature parameters can be passed using this option and in
+ particular PSS.
+ [Steve Henson]
+
+ *) Add RSA PSS signing function. This will generate and set the
+ appropriate AlgorithmIdentifiers for PSS based on those in the
+ corresponding EVP_MD_CTX structure. No application support yet.
+ [Steve Henson]
+
+ *) Support for companion algorithm specific ASN1 signing routines.
+ New function ASN1_item_sign_ctx() signs a pre-initialised
+ EVP_MD_CTX structure and sets AlgorithmIdentifiers based on
+ the appropriate parameters.
+ [Steve Henson]
+
+ *) Add new algorithm specific ASN1 verification initialisation function
+ to EVP_PKEY_ASN1_METHOD: this is not in EVP_PKEY_METHOD since the ASN1
+ handling will be the same no matter what EVP_PKEY_METHOD is used.
+ Add a PSS handler to support verification of PSS signatures: checked
+ against a number of sample certificates.
+ [Steve Henson]
+
+ *) Add signature printing for PSS. Add PSS OIDs.
+ [Steve Henson, Martin Kaiser <lists@kaiser.cx>]
+
+ *) Add algorithm specific signature printing. An individual ASN1 method
+ can now print out signatures instead of the standard hex dump.
+
+ More complex signatures (e.g. PSS) can print out more meaningful
+ information. Include DSA version that prints out the signature
+ parameters r, s.
+ [Steve Henson]
+
+ *) Password based recipient info support for CMS library: implementing
+ RFC3211.
+ [Steve Henson]
+
+ *) 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]
+
+ *) 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)]
+
+ *) Fix PSK session representation.
+ [Bodo Moeller]
+
+ *) Add RC4-MD5 and AESNI-SHA1 "stitched" implementations.
+
+ This work was sponsored by Intel.
+ [Andy Polyakov]
+
+ *) 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.
+ [Steve Henson]
+
+ *) Expand range of ctrls for AES GCM. Permit setting invocation
+ field on decrypt and retrieval of invocation field only on encrypt.
+ [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.
+ [Steve Henson]
*) For FIPS capable OpenSSL interpret a NULL default public key method
as unset and return the appopriate default but do *not* set the default.
*) 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 1.0.0e and 1.0.0f [xx XXX xxxx]
+
+ *) 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)]
+
+ *) In ssl3_clear, preserve s3->init_extra along with s3->rbuf.
+ [Bob Buckholz (Google)]
+
+ Changes between 1.0.0d and 1.0.0e [6 Sep 2011]
+
+ *) Fix bug where CRLs with nextUpdate in the past are sometimes accepted
+ 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:
Changes between 0.9.8r and 0.9.8s [xx XXX xxxx]
+ *) 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).

+ [Bodo Moeller]
