OpenSSL CHANGES
_______________
- Changes between 1.0.2 and 1.1.0 [xx XXX xxxx]
+ Changes between 1.0.2f and 1.1.0 [xx XXX xxxx]
+
+ *) The INSTALL_PREFIX Makefile variable has been renamed to
+ DESTDIR. That makes for less confusion on what this variable
+ is for. Also, the configuration option --install_prefix is
+ removed.
+ [Richard Levitte]
+
+ *) Heartbeat for TLS has been removed and is disabled by default
+ for DTLS; configure with enable-heartbeats. Code that uses the
+ old #define's might need to be updated.
+ [Emilia Käsper, Rich Salz]
+
+ *) Rename REF_CHECK to REF_DEBUG.
+ [Rich Salz]
+
+ *) New "unified" build system
+
+ The "unified" build system is aimed to be a common system for all
+ platforms we support. With it comes new support for VMS.
+
+ This system builds supports building in a differnt directory tree
+ than the source tree. It produces one Makefile (for unix family
+ or lookalikes), or one descrip.mms (for VMS).
+
+ The source of information to make the Makefile / descrip.mms is
+ small files called 'build.info', holding the necessary
+ information for each directory with source to compile, and a
+ template in Configurations, like unix-Makefile.tmpl or
+ descrip.mms.tmpl.
+
+ We rely heavily on the perl module Text::Template.
+ [Richard Levitte]
+
+ *) Added support for auto-initialisation and de-initialisation of the library.
+ OpenSSL no longer requires explicit init or deinit routines to be called,
+ except in certain circumstances. See the OPENSSL_init_crypto() and
+ OPENSSL_init_ssl() man pages for further information.
+ [Matt Caswell]
+
+ *) The arguments to the DTLSv1_listen function have changed. Specifically the
+ "peer" argument is now expected to be a BIO_ADDR object.
+
+ *) Rewrite of BIO networking library. The BIO library lacked consistent
+ support of IPv6, and adding it required some more extensive
+ modifications. This introduces the BIO_ADDR and BIO_ADDRINFO types,
+ which hold all types of addresses and chains of address information.
+ It also introduces a new API, with functions like BIO_socket,
+ BIO_connect, BIO_listen, BIO_lookup and a rewrite of BIO_accept.
+ The source/sink BIOs BIO_s_connect, BIO_s_accept and BIO_s_datagram
+ have been adapted accordingly.
+ [Richard Levitte]
+
+ *) RSA_padding_check_PKCS1_type_1 now accepts inputs with and without
+ the leading 0-byte.
+ [Emilia Käsper]
+
+ *) CRIME protection: disable compression by default, even if OpenSSL is
+ compiled with zlib enabled. Applications can still enable compression
+ by calling SSL_CTX_clear_options(ctx, SSL_OP_NO_COMPRESSION), or by
+ using the SSL_CONF library to configure compression.
+ [Emilia Käsper]
+
+ *) The signature of the session callback configured with
+ SSL_CTX_sess_set_get_cb was changed. The read-only input buffer
+ was explicitly marked as 'const unsigned char*' instead of
+ 'unsigned char*'.
+ [Emilia Käsper]
+
+ *) Always DPURIFY. Remove the use of uninitialized memory in the
+ RNG, and other conditional uses of DPURIFY. This makes -DPURIFY a no-op.
+ [Emilia Käsper]
+
+ *) Removed many obsolete configuration items, including
+ DES_PTR, DES_RISC1, DES_RISC2, DES_INT
+ MD2_CHAR, MD2_INT, MD2_LONG
+ BF_PTR, BF_PTR2
+ IDEA_SHORT, IDEA_LONG
+ RC2_SHORT, RC2_LONG, RC4_LONG, RC4_CHUNK, RC4_INDEX
+ [Rich Salz, with advice from Andy Polyakov]
+
+ *) Many BN internals have been moved to an internal header file.
+ [Rich Salz with help from Andy Polyakov]
+
+ *) Configuration and writing out the results from it has changed.
+ Files such as Makefile include/openssl/opensslconf.h and are now
+ produced through general templates, such as Makefile.in and
+ crypto/opensslconf.h.in and some help from the perl module
+ Text::Template.
+
+ Also, the center of configuration information is no longer
+ Makefile. Instead, Configure produces a perl module in
+ configdata.pm which holds most of the config data (in the hash
+ table %config), the target data that comes from the target
+ configuration in one of the Configurations/*.conf files (in
+ %target).
+ [Richard Levitte]
+
+ *) To clarify their intended purposes, the Configure options
+ --prefix and --openssldir change their semantics, and become more
+ straightforward and less interdependent.
+
+ --prefix shall be used exclusively to give the location INSTALLTOP
+ where programs, scripts, libraries, include files and manuals are
+ going to be installed. The default is now /usr/local.
+
+ --openssldir shall be used exclusively to give the default
+ location OPENSSLDIR where certificates, private keys, CRLs are
+ managed. This is also where the default openssl.cnf gets
+ installed.
+ If the directory given with this option is a relative path, the
+ values of both the --prefix value and the --openssldir value will
+ be combined to become OPENSSLDIR.
+ The default for --openssldir is INSTALLTOP/ssl.
+
+ Anyone who uses --openssldir to specify where OpenSSL is to be
+ installed MUST change to use --prefix instead.
+ [Richard Levitte]
+
+ *) The GOST engine was out of date and therefore it has been removed. An up
+ to date GOST engine is now being maintained in an external repository.
+ See: https://wiki.openssl.org/index.php/Binaries. Libssl still retains
+ support for GOST ciphersuites (these are only activated if a GOST engine
+ is present).
+ [Matt Caswell]
+
+ *) EGD is no longer supported by default; use enable-egd when
+ configuring.
+ [Ben Kaduk and Rich Salz]
+
+ *) The distribution now has Makefile.in files, which are used to
+ create Makefile's when Configure is run. *Configure must be run
+ before trying to build now.*
+ [Rich Salz]
+
+ *) The return value for SSL_CIPHER_description() for error conditions
+ has changed.
+ [Rich Salz]
+
+ *) Support for RFC6698/RFC7671 DANE TLSA peer authentication.
+
+ Obtaining and performing DNSSEC validation of TLSA records is
+ the application's responsibility. The application provides
+ the TLSA records of its choice to OpenSSL, and these are then
+ used to authenticate the peer.
+
+ The TLSA records need not even come from DNS. They can, for
+ example, be used to implement local end-entity certificate or
+ trust-anchor "pinning", where the "pin" data takes the form
+ of TLSA records, which can augment or replace verification
+ based on the usual WebPKI public certification authorities.
+ [Viktor Dukhovni]
+
+ *) Revert default OPENSSL_NO_DEPRECATED setting. Instead OpenSSL
+ continues to support deprecated interfaces in default builds.
+ However, applications are strongly advised to compile their
+ source files with -DOPENSSL_API_COMPAT=0x10100000L, which hides
+ the declarations of all interfaces deprecated in 0.9.8, 1.0.0
+ or the 1.1.0 releases.
+
+ In environments in which all applications have been ported to
+ not use any deprecated interfaces OpenSSL's Configure script
+ should be used with the --api=1.1.0 option to entirely remove
+ support for the deprecated features from the library and
+ unconditionally disable them in the installed headers.
+ Essentially the same effect can be achieved with the "no-deprecated"
+ argument to Configure, except that this will always restrict
+ the build to just the latest API, rather than a fixed API
+ version.
+
+ As applications are ported to future revisions of the API,
+ they should update their compile-time OPENSSL_API_COMPAT define
+ accordingly, but in most cases should be able to continue to
+ compile with later releases.
+
+ The OPENSSL_API_COMPAT versions for 1.0.0, and 0.9.8 are
+ 0x10000000L and 0x00908000L, respectively. However those
+ versions did not support the OPENSSL_API_COMPAT feature, and
+ so applications are not typically tested for explicit support
+ of just the undeprecated features of either release.
+ [Viktor Dukhovni]
+
+ *) Add support for setting the minimum and maximum supported protocol.
+ It can bet set via the SSL_set_min_proto_version() and
+ SSL_set_max_proto_version(), or via the SSL_CONF's MinProtocol and
+ MaxProtcol. It's recommended to use the new APIs to disable
+ protocols instead of disabling individual protocols using
+ SSL_set_options() or SSL_CONF's Protocol. This change also
+ removes support for disabling TLS 1.2 in the OpenSSL TLS
+ client at compile time by defining OPENSSL_NO_TLS1_2_CLIENT.
+ [Kurt Roeckx]
+
+ *) 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]
+
+ *) Made EVP_MD_CTX, EVP_MD, EVP_CIPHER_CTX, EVP_CIPHER 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 and EVP_CIPHER, complete APIs to create, fill and
+ destroy such methods has been added. See EVP_MD_meth_new(3) and
+ EVP_CIPHER_meth_new(3) for documentation.
+
+ Additional changes:
+ 1) EVP_MD_CTX_cleanup(), EVP_CIPHER_CTX_cleanup() and
+ HMAC_CTX_cleanup() were removed. HMAC_CTX_reset() and
+ EVP_MD_CTX_reset() should be called instead to reinitialise
+ an already created structure.
+ 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, gmp,
+ and sureware.
+ [Matt Caswell, Rich Salz]
+
+ *) 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]
+
+ *) Revamped memory debug; only -DCRYPTO_MDEBUG and -DCRYPTO_MDEBUG_ABORT
+ are used; the latter aborts on memory leaks (usually checked on exit).
+ Some undocumented "set malloc, etc., hooks" functions were removed
+ and others were changed. All are now documented.
+ [Rich Salz]
+
+ *) 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
+ at https://www.openssl.org/source/OCB-patent-grant-OpenSSL.pdf. Support
for OCB can be removed by calling config with no-ocb.
[Matt Caswell]
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 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>]
[mancha <mancha1@zoho.com>]
*) Fix eckey_priv_encode so it immediately returns an error upon a failure
- in i2d_ECPrivateKey.
+ 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.
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.

*) New -verify_name option in command line utilities to set verification
parameters by name.

[Steve Henson]
- Changes between 1.0.2 and 1.0.2a [xx XXX xxxx]
+ Changes between 1.0.2e and 1.0.2f [28 Jan 2016]
+ *) DH small subgroups
+
+ Historically OpenSSL only ever generated DH parameters based on "safe"
+ primes. More recently (in version 1.0.2) support was provided for
+ generating X9.42 style parameter files such as those required for RFC 5114
+ support. The primes used in such files may not be "safe". Where an
+ application is using DH configured with parameters based on primes that are
+ not "safe" then an attacker could use this fact to find a peer's private
+ DH exponent. This attack requires that the attacker complete multiple
+ handshakes in which the peer uses the same private DH exponent. For example
+ this could be used to discover a TLS server's private DH exponent if it's
+ reusing the private DH exponent or it's using a static DH ciphersuite.
+
+ OpenSSL provides the option SSL_OP_SINGLE_DH_USE for ephemeral DH (DHE) in
+ TLS. It is not on by default. If the option is not set then the server
+ reuses the same private DH exponent for the life of the server process and
+ would be vulnerable to this attack. It is believed that many popular
+ applications do set this option and would therefore not be at risk.
+
+ The fix for this issue adds an additional check where a "q" parameter is
+ available (as is the case in X9.42 based parameters). This detects the
+ only known attack, and is the only possible defense for static DH
+ ciphersuites. This could have some performance impact.
+
+ Additionally the SSL_OP_SINGLE_DH_USE option has been switched on by
+ default and cannot be disabled. This could have some performance impact.
+
+ This issue was reported to OpenSSL by Antonio Sanso (Adobe).
+ (CVE-2016-0701)
+ [Matt Caswell]
+
+ *) SSLv2 doesn't block disabled ciphers
+
+ A malicious client can negotiate SSLv2 ciphers that have been disabled on
+ the server and complete SSLv2 handshakes even if all SSLv2 ciphers have
+ been disabled, provided that the SSLv2 protocol was not also disabled via
+ SSL_OP_NO_SSLv2.
+
+ This issue was reported to OpenSSL on 26th December 2015 by Nimrod Aviram
+ and Sebastian Schinzel.
+ (CVE-2015-3197)
+ [Viktor Dukhovni]
+
+ 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.

+
+ 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.
