Changes between 1.0.2 and 1.1.0 [xx XXX xxxx]
+ *) 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.
[mancha <mancha1@zoho.com>]
[Steve Henson]
- *) Add callbacks supporting generation and retrieval of supplemental
- data entries.
- [Scott Deboy <sdeboy@apache.org>, Trevor Perrin and Ben Laurie]
-
*) 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
whose return value is often ignored.
[Steve Henson]
- Changes between 1.0.1e and 1.0.2 [xx XXX xxxx]
+ Changes between 1.0.1h and 1.0.2 [xx XXX xxxx]
- *) Keep original DTLS digest and encryption contexts in retransmission
- structures so we can use the previous session parameters if they need
- to be resent. (CVE-2013-6450)
- [Steve Henson]
+ *) Fix ec_GFp_simple_points_make_affine (thus, EC_POINTs_mul etc.)
+ for corner cases. (Certain input points at infinity could lead to
+ bogus results, with non-infinity inputs mapped to infinity too.)
+ [Bodo Moeller]
- *) TLS pad extension: draft-agl-tls-padding-03
+ *) Initial support for PowerISA 2.0.7, first implemented in POWER8.
+ This covers AES, SHA256/512 and GHASH. "Initial" means that most
+ common cases are optimized and there still is room for further
+ improvements. Vector Permutation AES for Altivec is also added.
+ [Andy Polyakov]
- Workaround for the "TLS hang bug" (see FAQ and PR#2771): if the
- TLS client Hello record length value would otherwise be > 255 and
- less that 512 pad with a dummy extension containing zeroes so it
- is at least 512 bytes long.
+ *) Add support for little-endian ppc64 Linux target.
+ [Marcelo Cerri (IBM)]
- [Adam Langley, Steve Henson]
+ *) Initial support for AMRv8 ISA crypto extensions. This covers AES,
+ SHA1, SHA256 and GHASH. "Initial" means that most common cases
+ are optimized and there still is room for further improvements.
+ Both 32- and 64-bit modes are supported.
+ [Andy Polyakov, Ard Biesheuvel (Linaro)]
+
+ *) Improved ARMv7 NEON support.
+ [Andy Polyakov]
+
+ *) Support for SPARC Architecture 2011 crypto extensions, first
+ implemented in SPARC T4. This covers AES, DES, Camellia, SHA1,
+ SHA256/512, MD5, GHASH and modular exponentiation.
+ [Andy Polyakov, David Miller]
+
+ *) Accelerated modular exponentiation for Intel processors, a.k.a.
+ RSAZ.
+ [Shay Gueron (Intel Corp)]
+
+ *) Support for new and upcoming Intel processors, including AVX2,
+ BMI and SHA ISA extensions. This includes additional "stitched"
+ implementations, AESNI-SHA256 and GCM, and multi-buffer support
+ for TLS encrypt.
+
+ This work was sponsored by Intel Corp.
+ [Andy Polyakov]
+
+ *) Use algorithm specific chains in SSL_CTX_use_certificate_chain_file():
+ this fixes a limiation in previous versions of OpenSSL.
+ [Steve Henson]
+
+ *) Extended RSA OAEP support via EVP_PKEY API. Options to specify digest,
+ MGF1 digest and OAEP label.
+ [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]
*) Add functions to allocate and set the fields of an ECDSA_METHOD
structure.
[Douglas E. Engert, Steve Henson]
- *) Add option SSL_OP_SAFARI_ECDHE_ECDSA_BUG (part of SSL_OP_ALL) which
- avoids preferring ECDHE-ECDSA ciphers when the client appears to be
- Safari on OS X. Safari on OS X 10.8..10.8.3 advertises support for
- several ECDHE-ECDSA ciphers, but fails to negotiate them. The bug
- is fixed in OS X 10.8.4, but Apple have ruled out both hot fixing
- 10.8..10.8.3 and forcing users to upgrade to 10.8.4 or newer.
- [Rob Stradling, Adam Langley]
-
*) New functions OPENSSL_gmtime_diff and ASN1_TIME_diff to find the
difference in days and seconds between two tm or ASN1_TIME structures.
[Steve Henson]
*) Support for linux-x32, ILP32 environment in x86_64 framework.
[Andy Polyakov]
- *) RFC 5878 (TLS Authorization Extensions) support.
- [Emilia Kasper, Adam Langley, Ben Laurie (Google)]
-
*) Experimental multi-implementation support for FIPS capable OpenSSL.
When in FIPS mode the approved implementations are used as normal,
when not in FIPS mode the internal unapproved versions are used instead.

+ Changes between 1.0.1g and 1.0.1h [5 Jun 2014]
+
+ *) Fix for SSL/TLS MITM flaw. An attacker using a carefully crafted
+ handshake can force the use of weak keying material in OpenSSL
+ SSL/TLS clients and servers.
+
+ Thanks to KIKUCHI Masashi (Lepidum Co. Ltd.) for discovering and
+ researching this issue. (CVE-2014-0224)
+ [KIKUCHI Masashi, Steve Henson]
+
+ *) Fix DTLS recursion flaw. By sending an invalid DTLS handshake to an
+ OpenSSL DTLS client the code can be made to recurse eventually crashing
+ in a DoS attack.
+
+ Thanks to Imre Rad (Search-Lab Ltd.) for discovering this issue.
+ (CVE-2014-0221)
+ [Imre Rad, Steve Henson]
+
+ *) Fix DTLS invalid fragment vulnerability. A buffer overrun attack can
+ be triggered by sending invalid DTLS fragments to an OpenSSL DTLS
+ client or server. This is potentially exploitable to run arbitrary
+ code on a vulnerable client or server.
+
+ Thanks to Jüri Aedla for reporting this issue. (CVE-2014-0195)
+ [Jüri Aedla, Steve Henson]
+
+ *) Fix bug in TLS code where clients enable anonymous ECDH ciphersuites
+ are subject to a denial of service attack.
+
+ Thanks to Felix Gröbert and Ivan Fratric at Google for discovering
+ this issue. (CVE-2014-3470)
+ [Felix Gröbert, Ivan Fratric, Steve Henson]
+
+ *) Harmonize version and its documentation. -f flag is used to display

+ [mancha <mancha1@zoho.com>]
+
+ *) Fix some double frees. These are not thought to be exploitable.
+ [mancha <mancha1@zoho.com>]
+
+ Changes between 1.0.1f and 1.0.1g [7 Apr 2014]
+
+ *) 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

+ [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]

+ [Adam Langley, Steve Henson]
+
+ Changes between 1.0.1e and 1.0.1f [6 Jan 2014]
+
+ *) Fix for TLS record tampering bug. A carefully crafted invalid
+ handshake could crash OpenSSL with a NULL pointer exception.
+ Thanks to Anton Johansson for reporting this issues.
+ (CVE-2013-4353)

Changes between 1.0.1d and 1.0.1e [11 Feb 2013]
*) Correct fix for CVE-2013-0169. The original didn't work on AES-NI
This fixes a DoS attack. (CVE-2013-0166)
[Steve Henson]
- *) Return an error when checking OCSP signatures when key is NULL.
- This fixes a DoS attack. (CVE-2013-0166)
- [Steve Henson]
-
*) Call OCSP Stapling callback after ciphersuite has been chosen, so
the right response is stapled. Also change SSL_get_certificate()
so it returns the certificate actually sent.
