OpenSSL CHANGES
_______________
- Changes between 1.0.2g and 1.1.0 [xx XXX xxxx]
+ This is a high-level summary of the most important changes.
+ For a full list of changes, see the git commit log; for example,
+ https://github.com/openssl/openssl/commits/ and pick the appropriate
+ release branch.
+
+ Changes between 1.1.0f and 1.1.1 [xx XXX xxxx]
+
+ *) Added SHA512/224 and SHA512/256 algorithm support.
+ [Paul Dale]
+
+ *) The last traces of Netware support, first removed in 1.1.0, have
+ now been removed.
+ [Rich Salz]
+
+ *) Get rid of Makefile.shared, and in the process, make the processing
+ of certain files (rc.obj, or the .def/.map/.opt files produced from
+ the ordinal files) more visible and hopefully easier to trace and
+ debug (or make silent).
+ [Richard Levitte]
+
+ *) Make it possible to have environment variable assignments as
+ arguments to config / Configure.
+ [Richard Levitte]
+
+ *) Add multi-prime RSA (RFC 8017) support.
+ [Paul Yang]
+
+ *) Add SM3 implemented according to GB/T 32905-2016
+ [ Jack Lloyd <jack.lloyd@ribose.com>,
+ Ronald Tse <ronald.tse@ribose.com>,
+ Erick Borsboom <erick.borsboom@ribose.com> ]
+
+ *) Add 'Maximum Fragment Length' TLS extension negotiation and support
+ as documented in RFC6066.
+ Based on a patch from Tomasz Moń
+ [Filipe Raimundo da Silva]
+
+ *) Add SM4 implemented according to GB/T 32907-2016.
+ [ Jack Lloyd <jack.lloyd@ribose.com>,
+ Ronald Tse <ronald.tse@ribose.com>,
+ Erick Borsboom <erick.borsboom@ribose.com> ]
+
+ *) Reimplement -newreq-nodes and ERR_error_string_n; the
+ original author does not agree with the license change.
+ [Rich Salz]
+
+ *) Add ARIA AEAD TLS support.
+ [Jon Spillett]
+
+ *) Some macro definitions to support VS6 have been removed. Visual
+ Studio 6 has not worked since 1.1.0
+ [Rich Salz]
+
+ *) Add ERR_clear_last_mark(), to allow callers to clear the last mark
+ without clearing the errors.
+ [Richard Levitte]
+
+ *) Add "atfork" functions. If building on a system that without
+ pthreads, see doc/man3/OPENSSL_fork_prepare.pod for application
+ requirements. The RAND facility now uses/requires this.
+ [Rich Salz]
+
+ *) Add SHA3.
+ [Andy Polyakov]
+
+ *) The UI API becomes a permanent and integral part of libcrypto, i.e.
+ not possible to disable entirely. However, it's still possible to
+ disable the console reading UI method, UI_OpenSSL() (use UI_null()
+ as a fallback).
+
+ To disable, configure with 'no-ui-console'. 'no-ui' is still
+ possible to use as an alias. Check at compile time with the
+ macro OPENSSL_NO_UI_CONSOLE. The macro OPENSSL_NO_UI is still
+ possible to check and is an alias for OPENSSL_NO_UI_CONSOLE.
+ [Richard Levitte]
+
+ *) Add a STORE module, which implements a uniform and URI based reader of
+ stores that can contain keys, certificates, CRLs and numerous other
+ objects. The main API is loosely based on a few stdio functions,
+ and includes OSSL_STORE_open, OSSL_STORE_load, OSSL_STORE_eof,
+ OSSL_STORE_error and OSSL_STORE_close.
+ The implementation uses backends called "loaders" to implement arbitrary
+ URI schemes. There is one built in "loader" for the 'file' scheme.
+ [Richard Levitte]
+
+ *) Add devcrypto engine. This has been implemented against cryptodev-linux,
+ then adjusted to work on FreeBSD 8.4 as well.
+ Enable by configuring with 'enable-devcryptoeng'. This is done by default
+ on BSD implementations, as cryptodev.h is assumed to exist on all of them.
+ [Richard Levitte]
+
+ *) Module names can prefixed with OSSL_ or OPENSSL_. This affects
+ util/mkerr.pl, which is adapted to allow those prefixes, leading to
+ error code calls like this:
+
+ OSSL_FOOerr(OSSL_FOO_F_SOMETHING, OSSL_FOO_R_WHATEVER);
+
+ With this change, we claim the namespaces OSSL and OPENSSL in a manner
+ that can be encoded in C. For the foreseeable future, this will only
+ affect new modules.
+ [Richard Levitte and Tim Hudson]
+
+ *) Removed BSD cryptodev engine.
+ [Rich Salz]
+
+ *) Add a build target 'build_all_generated', to build all generated files
+ and only that. This can be used to prepare everything that requires
+ things like perl for a system that lacks perl and then move everything
+ to that system and do the rest of the build there.
+ [Richard Levitte]
+
+ *) In the UI interface, make it possible to duplicate the user data. This
+ can be used by engines that need to retain the data for a longer time
+ than just the call where this user data is passed.
+ [Richard Levitte]
+
+ *) Ignore the '-named_curve auto' value for compatibility of applications
+ with OpenSSL 1.0.2.
+ [Tomas Mraz <tmraz@fedoraproject.org>]
+
+ *) Fragmented SSL/TLS alerts are no longer accepted. An alert message is 2
+ bytes long. In theory it is permissible in SSLv3 - TLSv1.2 to fragment such
+ alerts across multiple records (some of which could be empty). In practice
+ it make no sense to send an empty alert record, or to fragment one. TLSv1.3
+ prohibts this altogether and other libraries (BoringSSL, NSS) do not
+ support this at all. Supporting it adds significant complexity to the
+ record layer, and its removal is unlikely to cause inter-operability
+ issues.
+ [Matt Caswell]
+
+ *) Add the ASN.1 types INT32, UINT32, INT64, UINT64 and variants prefixed
+ with Z. These are meant to replace LONG and ZLONG and to be size safe.
+ The use of LONG and ZLONG is discouraged and scheduled for deprecation
+ in OpenSSL 1.2.0.
+ [Richard Levitte]
+
+ *) Add the 'z' and 'j' modifiers to BIO_printf() et al formatting string,
+ 'z' is to be used for [s]size_t, and 'j' - with [u]int64_t.
+ [Richard Levitte, Andy Polyakov]
+
+ *) Add EC_KEY_get0_engine(), which does for EC_KEY what RSA_get0_engine()
+ does for RSA, etc.
+ [Richard Levitte]
+
+ *) Have 'config' recognise 64-bit mingw and choose 'mingw64' as the target
+ platform rather than 'mingw'.
+ [Richard Levitte]
+
+ *) The functions X509_STORE_add_cert and X509_STORE_add_crl return
+ success if they are asked to add an object which already exists
+ in the store. This change cascades to other functions which load
+ certificates and CRLs.
+ [Paul Dale]
+
+ *) x86_64 assembly pack: annotate code with DWARF CFI directives to
+ facilitate stack unwinding even from assembly subroutines.
+ [Andy Polyakov]
+
+ *) Remove VAX C specific definitions of OPENSSL_EXPORT, OPENSSL_EXTERN.
+ Also remove OPENSSL_GLOBAL entirely, as it became a no-op.
+ [Richard Levitte]
+
+ *) Remove the VMS-specific reimplementation of gmtime from crypto/o_times.c.
+ VMS C's RTL has a fully up to date gmtime() and gmtime_r() since V7.1,
+ which is the minimum version we support.
+ [Richard Levitte]
+
+ *) Certificate time validation (X509_cmp_time) enforces stricter
+ compliance with RFC 5280. Fractional seconds and timezone offsets
+ are no longer allowed.
+ [Emilia Käsper]
+
+ *) Add support for ARIA
+ [Paul Dale]
+
+ *) s_client will now send the Server Name Indication (SNI) extension by
+ default unless the new "-noservername" option is used. The server name is
+ based on the host provided to the "-connect" option unless overridden by
+ using "-servername".
+ [Matt Caswell]
+
+ *) Add support for SipHash
+ [Todd Short]
+
+ *) OpenSSL now fails if it receives an unrecognised record type in TLS1.0
+ or TLS1.1. Previously this only happened in SSLv3 and TLS1.2. This is to
+ prevent issues where no progress is being made and the peer continually
+ sends unrecognised record types, using up resources processing them.
+ [Matt Caswell]
+
+ *) 'openssl passwd' can now produce SHA256 and SHA512 based output,
+ using the algorithm defined in
+ https://www.akkadia.org/drepper/SHA-crypt.txt
+ [Richard Levitte]
+
+ *) Heartbeat support has been removed; the ABI is changed for now.
+ [Richard Levitte, Rich Salz]
+
+ *) Support for SSL_OP_NO_ENCRYPT_THEN_MAC in SSL_CONF_cmd.
+ [Emilia Käsper]
+
+ *) The RSA "null" method, which was partially supported to avoid patent
+ issues, has been replaced to always returns NULL.
+ [Rich Salz]
+
+ Changes between 1.1.0g and 1.1.0h [xx XXX xxxx]
+
+ *) Removed the OS390-Unix config target. It relied on a script that doesn't
+ exist.
+ [Rich Salz]
+
+ *) rsaz_1024_mul_avx2 overflow bug on x86_64
+
+ There is an overflow bug in the AVX2 Montgomery multiplication procedure
+ used in exponentiation with 1024-bit moduli. 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 DH1024 are considered just feasible, 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
+ significant. However, for an attack on TLS to be meaningful, the server
+ would have to share the DH1024 private key among multiple clients, which is
+ no longer an option since CVE-2016-0701.
+
+ This only affects processors that support the AVX2 but not ADX extensions
+ like Intel Haswell (4th generation).
+
+ This issue was reported to OpenSSL by David Benjamin (Google). The issue
+ was originally found via the OSS-Fuzz project.
+ (CVE-2017-3738)
+ [Andy Polyakov]
+
+ Changes between 1.1.0f and 1.1.0g [2 Nov 2017]
+
+ *) bn_sqrx8x_internal carry bug 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.
+
+ This only affects processors that support the BMI1, BMI2 and ADX extensions
+ like Intel Broadwell (5th generation) and later or AMD Ryzen.
+
+ This issue was reported to OpenSSL by the OSS-Fuzz project.
+ (CVE-2017-3736)
+ [Andy Polyakov]
+
+ *) Malformed X.509 IPAddressFamily could cause OOB read
+
+ If an X.509 certificate has a malformed IPAddressFamily extension,
+ OpenSSL could do a one-byte buffer overread. The most likely result
+ would be an erroneous display of the certificate in text format.
+
+ This issue was reported to OpenSSL by the OSS-Fuzz project.
+ (CVE-2017-3735)
+ [Rich Salz]
+
+ Changes between 1.1.0e and 1.1.0f [25 May 2017]
+
+ *) Have 'config' recognise 64-bit mingw and choose 'mingw64' as the target
+ platform rather than 'mingw'.
+ [Richard Levitte]
+
+ *) Remove the VMS-specific reimplementation of gmtime from crypto/o_times.c.
+ VMS C's RTL has a fully up to date gmtime() and gmtime_r() since V7.1,
+ which is the minimum version we support.
+ [Richard Levitte]
+
+ Changes between 1.1.0d and 1.1.0e [16 Feb 2017]
+
+ *) Encrypt-Then-Mac renegotiation crash
+
+ During a renegotiation handshake if the Encrypt-Then-Mac extension is
+ negotiated where it was not in the original handshake (or vice-versa) then
+ this can cause OpenSSL to crash (dependant on ciphersuite). Both clients
+ and servers are affected.
+
+ This issue was reported to OpenSSL by Joe Orton (Red Hat).
+ (CVE-2017-3733)
+ [Matt Caswell]
+
+ Changes between 1.1.0c and 1.1.0d [26 Jan 2017]
+
+ *) Truncated packet could crash via OOB read
+
+ If one side of an SSL/TLS path is running on a 32-bit host and a specific
+ cipher is being used, then a truncated packet can cause that host to
+ perform an out-of-bounds read, usually resulting in a crash.
+
+ This issue was reported to OpenSSL by Robert Święcki of Google.
+ (CVE-2017-3731)
+ [Andy Polyakov]
+
+ *) Bad (EC)DHE parameters cause a client crash
+
+ If a malicious server supplies bad parameters for a DHE or ECDHE key
+ exchange then this can result in the client attempting to dereference a
+ NULL pointer leading to a client crash. This could be exploited in a Denial
+ of Service attack.
+
+ This issue was reported to OpenSSL by Guido Vranken.
+ (CVE-2017-3730)
+ [Matt Caswell]
+
+ *) 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. Note: This issue is very
+ similar to CVE-2015-3193 but must be treated as a separate problem.
+
+ This issue was reported to OpenSSL by the OSS-Fuzz project.
+ (CVE-2017-3732)
+ [Andy Polyakov]
+
+ Changes between 1.1.0b and 1.1.0c [10 Nov 2016]
+
+ *) ChaCha20/Poly1305 heap-buffer-overflow
+
+ TLS connections using *-CHACHA20-POLY1305 ciphersuites are susceptible to
+ a DoS attack by corrupting larger payloads. This can result in an OpenSSL
+ crash. This issue is not considered to be exploitable beyond a DoS.
+
+ This issue was reported to OpenSSL by Robert Święcki (Google Security Team)
+ (CVE-2016-7054)
+ [Richard Levitte]
+
+ *) CMS Null dereference
+
+ Applications parsing invalid CMS structures can crash with a NULL pointer
+ dereference. This is caused by a bug in the handling of the ASN.1 CHOICE
+ type in OpenSSL 1.1.0 which can result in a NULL value being passed to the
+ structure callback if an attempt is made to free certain invalid encodings.
+ Only CHOICE structures using a callback which do not handle NULL value are
+ affected.
+
+ This issue was reported to OpenSSL by Tyler Nighswander of ForAllSecure.
+ (CVE-2016-7053)
+ [Stephen Henson]
+
+ *) Montgomery multiplication may produce incorrect results
+
+ There is a carry propagating bug in the Broadwell-specific Montgomery
+ multiplication procedure that handles input lengths divisible by, but
+ longer than 256 bits. Analysis suggests that attacks against RSA, DSA
+ and DH private keys are impossible. This is because the subroutine in
+ question is not used in operations with the private key itself and an input
+ of the attacker's direct choice. Otherwise the bug can manifest itself as
+ transient authentication and key negotiation failures or reproducible
+ erroneous outcome of public-key operations with specially crafted input.
+ Among EC algorithms only Brainpool P-512 curves are affected and one
+ presumably can attack ECDH key negotiation. Impact was not analyzed in
+ detail, because pre-requisites for attack are considered unlikely. Namely
+ multiple clients have to choose the curve in question and the server has to
+ share the private key among them, neither of which is default behaviour.
+ Even then only clients that chose the curve will be affected.
+
+ This issue was publicly reported as transient failures and was not
+ initially recognized as a security issue. Thanks to Richard Morgan for
+ providing reproducible case.
+ (CVE-2016-7055)
+ [Andy Polyakov]
+
+ *) Removed automatic addition of RPATH in shared libraries and executables,
+ as this was a remainder from OpenSSL 1.0.x and isn't needed any more.
+ [Richard Levitte]
+
+ Changes between 1.1.0a and 1.1.0b [26 Sep 2016]
+
+ *) Fix Use After Free for large message sizes
+
+ The patch applied to address CVE-2016-6307 resulted in an issue where if a
+ message larger than approx 16k is received then the underlying buffer to
+ store the incoming message is reallocated and moved. Unfortunately a
+ dangling pointer to the old location is left which results in an attempt to
+ write to the previously freed location. This is likely to result in a
+ crash, however it could potentially lead to execution of arbitrary code.
+
+ This issue only affects OpenSSL 1.1.0a.
+
+ This issue was reported to OpenSSL by Robert Święcki.
+ (CVE-2016-6309)
+ [Matt Caswell]
+
+ Changes between 1.1.0 and 1.1.0a [22 Sep 2016]
+
+ *) OCSP Status Request extension unbounded memory growth
+
+ A malicious client can send an excessively large OCSP Status Request
+ extension. If that client continually requests renegotiation, sending a
+ large OCSP Status Request extension each time, then there will be unbounded
+ memory growth on the server. This will eventually lead to a Denial Of
+ Service attack through memory exhaustion. Servers with a default
+ configuration are vulnerable even if they do not support OCSP. Builds using
+ the "no-ocsp" build time option are not affected.
+
+ This issue was reported to OpenSSL by Shi Lei (Gear Team, Qihoo 360 Inc.)
+ (CVE-2016-6304)
+ [Matt Caswell]
+
+ *) SSL_peek() hang on empty record
+
+ OpenSSL 1.1.0 SSL/TLS will hang during a call to SSL_peek() if the peer
+ sends an empty record. This could be exploited by a malicious peer in a
+ Denial Of Service attack.
+
+ This issue was reported to OpenSSL by Alex Gaynor.
+ (CVE-2016-6305)
+ [Matt Caswell]
+
+ *) Excessive allocation of memory in tls_get_message_header() and
+ dtls1_preprocess_fragment()
+
+ A (D)TLS message includes 3 bytes for its length in the header for the
+ message. This would allow for messages up to 16Mb in length. Messages of
+ this length are excessive and OpenSSL includes a check to ensure that a
+ peer is sending reasonably sized messages in order to avoid too much memory
+ being consumed to service a connection. A flaw in the logic of version
+ 1.1.0 means that memory for the message is allocated too early, prior to
+ the excessive message length check. Due to way memory is allocated in
+ OpenSSL this could mean an attacker could force up to 21Mb to be allocated
+ to service a connection. This could lead to a Denial of Service through
+ memory exhaustion. However, the excessive message length check still takes
+ place, and this would cause the connection to immediately fail. Assuming
+ that the application calls SSL_free() on the failed connection in a timely
+ manner then the 21Mb of allocated memory will then be immediately freed
+ again. Therefore the excessive memory allocation will be transitory in
+ nature. This then means that there is only a security impact if:
+
+ 1) The application does not call SSL_free() in a timely manner in the event
+ that the connection fails
+ or
+ 2) The application is working in a constrained environment where there is
+ very little free memory
+ or
+ 3) The attacker initiates multiple connection attempts such that there are
+ multiple connections in a state where memory has been allocated for the
+ connection; SSL_free() has not yet been called; and there is insufficient
+ memory to service the multiple requests.
+
+ Except in the instance of (1) above any Denial Of Service is likely to be
+ transitory because as soon as the connection fails the memory is
+ subsequently freed again in the SSL_free() call. However there is an
+ increased risk during this period of application crashes due to the lack of
+ memory - which would then mean a more serious Denial of Service.
+
+ This issue was reported to OpenSSL by Shi Lei (Gear Team, Qihoo 360 Inc.)
+ (CVE-2016-6307 and CVE-2016-6308)
+ [Matt Caswell]
+
+ *) solaris-x86-cc, i.e. 32-bit configuration with vendor compiler,
+ had to be removed. Primary reason is that vendor assembler can't
+ assemble our modules with -KPIC flag. As result it, assembly
+ support, was not even available as option. But its lack means
+ lack of side-channel resistant code, which is incompatible with
+ security by todays standards. Fortunately gcc is readily available
+ prepackaged option, which we firmly point at...
+ [Andy Polyakov]
+
+ Changes between 1.0.2h and 1.1.0 [25 Aug 2016]
+
+ *) Windows command-line tool supports UTF-8 opt-in option for arguments
+ and console input. Setting OPENSSL_WIN32_UTF8 environment variable
+ (to any value) allows Windows user to access PKCS#12 file generated
+ with Windows CryptoAPI and protected with non-ASCII password, as well
+ as files generated under UTF-8 locale on Linux also protected with
+ non-ASCII password.
+ [Andy Polyakov]
+
+ *) To mitigate the SWEET32 attack (CVE-2016-2183), 3DES cipher suites
+ have been disabled by default and removed from DEFAULT, just like RC4.
+ See the RC4 item below to re-enable both.
+ [Rich Salz]
+
+ *) The method for finding the storage location for the Windows RAND seed file
+ has changed. First we check %RANDFILE%. If that is not set then we check
+ the directories %HOME%, %USERPROFILE% and %SYSTEMROOT% in that order. If
+ all else fails we fall back to C:\.
+ [Matt Caswell]
+
+ *) The EVP_EncryptUpdate() function has had its return type changed from void
+ to int. A return of 0 indicates and error while a return of 1 indicates
+ success.
+ [Matt Caswell]
+
+ *) The flags RSA_FLAG_NO_CONSTTIME, DSA_FLAG_NO_EXP_CONSTTIME and
+ DH_FLAG_NO_EXP_CONSTTIME which previously provided the ability to switch
+ off the constant time implementation for RSA, DSA and DH have been made
+ no-ops and deprecated.
+ [Matt Caswell]
+
+ *) Windows RAND implementation was simplified to only get entropy by
+ calling CryptGenRandom(). Various other RAND-related tickets
+ were also closed.
+ [Joseph Wylie Yandle, Rich Salz]
+
+ *) The stack and lhash API's were renamed to start with OPENSSL_SK_
+ and OPENSSL_LH_, respectively. The old names are available
+ with API compatibility. They new names are now completely documented.
+ [Rich Salz]
+
+ *) Unify TYPE_up_ref(obj) methods signature.
+ SSL_CTX_up_ref(), SSL_up_ref(), X509_up_ref(), EVP_PKEY_up_ref(),
+ X509_CRL_up_ref(), X509_OBJECT_up_ref_count() methods are now returning an
+ int (instead of void) like all others TYPE_up_ref() methods.
+ So now these methods also check the return value of CRYPTO_atomic_add(),
+ and the validity of object reference counter.
+ [fdasilvayy@gmail.com]
+
+ *) With Windows Visual Studio builds, the .pdb files are installed
+ alongside the installed libraries and executables. For a static
+ library installation, ossl_static.pdb is the associate compiler
+ generated .pdb file to be used when linking programs.
+ [Richard Levitte]
+
+ *) Remove openssl.spec. Packaging files belong with the packagers.
+ [Richard Levitte]
+
+ *) Automatic Darwin/OSX configuration has had a refresh, it will now
+ recognise x86_64 architectures automatically. You can still decide
+ to build for a different bitness with the environment variable
+ KERNEL_BITS (can be 32 or 64), for example:
+
+ KERNEL_BITS=32 ./config
+
+ [Richard Levitte]
+
+ *) Change default algorithms in pkcs8 utility to use PKCS#5 v2.0,
+ 256 bit AES and HMAC with SHA256.
+ [Steve Henson]
+
+ *) Remove support for MIPS o32 ABI on IRIX (and IRIX only).
+ [Andy Polyakov]
+
+ *) Triple-DES ciphers have been moved from HIGH to MEDIUM.
+ [Rich Salz]
+
+ *) To enable users to have their own config files and build file templates,
+ Configure looks in the directory indicated by the environment variable
+ OPENSSL_LOCAL_CONFIG_DIR as well as the in-source Configurations/
+ directory. On VMS, OPENSSL_LOCAL_CONFIG_DIR is expected to be a logical
+ name and is used as is.
+ [Richard Levitte]
+
+ *) The following datatypes were made opaque: X509_OBJECT, X509_STORE_CTX,
+ X509_STORE, X509_LOOKUP, and X509_LOOKUP_METHOD. The unused type
+ X509_CERT_FILE_CTX was removed.
+ [Rich Salz]
+
+ *) "shared" builds are now the default. To create only static libraries use
+ the "no-shared" Configure option.
+ [Matt Caswell]
+
+ *) Remove the no-aes, no-hmac, no-rsa, no-sha and no-md5 Configure options.
+ All of these option have not worked for some while and are fundamental
+ algorithms.
+ [Matt Caswell]
+
+ *) Make various cleanup routines no-ops and mark them as deprecated. Most
+ global cleanup functions are no longer required because they are handled
+ via auto-deinit (see OPENSSL_init_crypto and OPENSSL_init_ssl man pages).
+ Explicitly de-initing can cause problems (e.g. where a library that uses
+ OpenSSL de-inits, but an application is still using it). The affected
+ functions are CONF_modules_free(), ENGINE_cleanup(), OBJ_cleanup(),
+ EVP_cleanup(), BIO_sock_cleanup(), CRYPTO_cleanup_all_ex_data(),
+ RAND_cleanup(), SSL_COMP_free_compression_methods(), ERR_free_strings() and
+ COMP_zlib_cleanup().
+ [Matt Caswell]
+
+ *) --strict-warnings no longer enables runtime debugging options
+ such as REF_DEBUG. Instead, debug options are automatically
+ enabled with '--debug' builds.
+ [Andy Polyakov, Emilia Käsper]
+
+ *) Made DH and DH_METHOD opaque. The structures for managing DH objects
+ have been moved out of the public header files. New functions for managing
+ these have been added.
+ [Matt Caswell]
+
+ *) Made RSA and RSA_METHOD opaque. The structures for managing RSA
+ objects have been moved out of the public header files. New
+ functions for managing these have been added.
+ [Richard Levitte]
+
+ *) Made DSA and DSA_METHOD opaque. The structures for managing DSA objects
+ have been moved out of the public header files. New functions for managing
+ these have been added.
+ [Matt Caswell]
+
+ *) Made BIO and BIO_METHOD opaque. The structures for managing BIOs have been
+ moved out of the public header files. New functions for managing these
+ have been added.
+ [Matt Caswell]
*) Removed no-rijndael as a config option. Rijndael is an old name for AES.
- [Matt Caswell}
+ [Matt Caswell]
*) Removed the mk1mf build scripts.
[Richard Levitte]
[Emilia Käsper]
*) Add X25519 support.
- Integrate support for X25519 into EC library. This includes support
+ Add ASN.1 and EVP_PKEY methods for X25519. This includes support
for public and private key encoding using the format documented in
- draft-josefsson-pkix-newcurves-01: specifically X25519 uses the
- OID from that draft, encodes public keys using little endian
- format in the ECPoint structure and private keys using

+ corruption.
+
+ Internally to OpenSSL the EVP_EncodeUpdate() function is primarily used by

+ An overflow can occur in the EVP_EncryptUpdate() function. If an attacker
+ is able to supply very large amounts of input data after a previous call to
+ EVP_EncryptUpdate() with a partial block then a length check can overflow
+ resulting in a heap corruption. Following an analysis of all OpenSSL
+ internal usage of the EVP_EncryptUpdate() function all usage is one of two
+ forms. The first form is where the EVP_EncryptUpdate() call is known to be
+ the first called function after an EVP_EncryptInit(), and therefore that
+ specific call must be safe. The second form is where the length passed to
+ EVP_EncryptUpdate() can be seen from the code to be some small value and
+ therefore there is no possibility of an overflow. Since all instances are
+ one of these two forms, it is believed that there can be no overflows in
+ internal code due to this problem. It should be noted that
+ EVP_DecryptUpdate() can call EVP_EncryptUpdate() in certain code paths.
+ Also EVP_CipherUpdate() is a synonym for EVP_EncryptUpdate(). All instances
+ of these calls have also been analysed too and it is believed there are no

structure. This will break anything that messed round

The X509_STORE API doesn't directly support the retrieval

and then examining the cache for matches. This is probably
the best we can do without throwing out X509_LOOKUP
entirely (maybe later...).
-
+
The X509_VERIFY_CTX structure has been enhanced considerably.
-
+
All certificate lookup operations now go via a get_issuer()
callback. Although this currently uses an X509_STORE it
can be replaced by custom lookups. This is a simple way
in future. A very simple version which uses a simple
STACK for its trusted certificate store is also provided
using X509_STORE_CTX_trusted_stack().
-

The verify_cb() and verify() callbacks now have equivalents
