OpenSSL CHANGES
_______________
- Changes between 1.0.1 and 1.1.0 [xx XXX xxxx]
+ Changes between 1.0.x and 1.1.0 [xx XXX xxxx]
- *) New ctrls to retrieve supported signature algorithms and
- supported curve values as an array of NIDs. Extend openssl utility
- to print out received values.
+ *) 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 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.
+ *) Extend CMS code to support RSA-PSS signatures and RSA-OAEP for
+ enveloped data.
[Steve Henson]
- *) Enhance SSL/TLS certificate chain handling to support different
- chains for each certificate instead of one chain in the parent SSL_CTX.
+ *) Extended RSA OAEP support via EVP_PKEY API. Options to specify digest,
+ MGF1 digest and OAEP label.
[Steve Henson]
- *) Support for fixed DH ciphersuite client authentication: where both
- server and client use DH certificates with common parameters.
+ *) Add callbacks for arbitrary TLS extensions.
+ [Trevor Perrin <trevp@trevp.net> and Ben Laurie]
+
+ *) Support for DTLS 1.2. This adds two sets of DTLS methods: DTLS_*_method()
+ supports both DTLS 1.2 and 1.0 and should use whatever version the peer
+ supports and DTLSv1_2_*_method() which supports DTLS 1.2 only.
[Steve Henson]
- *) Support for fixed DH ciphersuites: those requiring DH server
- certificates.
+ *) Make openssl verify return errors.
+ [Chris Palmer <palmer@google.com> and Ben Laurie]
+
+ *) Fix OCSP checking.
+ [Rob Stradling <rob.stradling@comodo.com> and Ben Laurie]
+
+ *) New option -crl_download in several openssl utilities to download CRLs
+ from CRLDP extension in 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.
+ *) Integrate hostname, email address and IP address checking with certificate
+ verification. New verify options supporting checking in openssl utility.
[Steve Henson]
- *) Initial experimental support for X9.42 DH parameter format: mainly
- to support use of 'q' parameter for RFC5114 parameters.
+ *) New function X509_CRL_diff to generate a delta CRL from the difference
+ of two full CRLs. Add support to "crl" utility.
[Steve Henson]
- *) Add DH parameters from RFC5114 including test data to dhtest.
+ *) New options -CRL and -CRLform for s_client and s_server for CRLs.
+ [Steve Henson]
+
+ *) Extend OCSP I/O functions so they can be used for simple general purpose
+ HTTP as well as OCSP. New wrapper function which can be used to download
+ CRLs using the OCSP API.
+ [Steve Henson]
+
+ *) New functions to set lookup_crls callback and to retrieve
+ X509_STORE from X509_STORE_CTX.
+ [Steve Henson]
+
+ *) New ctrl and macro to retrieve supported points extensions.
+ Print out extension in s_server and s_client.
+ [Steve Henson]
+
+ *) New function ASN1_TIME_diff to calculate the difference between two
+ ASN1_TIME structures or one structure and the current time.
+ [Steve Henson]
+
+ *) Fixes and wildcard matching support to hostname and email checking
+ functions. Add manual page.
+ [Florian Weimer (Red Hat Product Security Team)]
+
+ *) New experimental SSL_CONF* functions. These provide a common framework
+ for application configuration using configuration files or command lines.
+ [Steve Henson]
+
+ *) New functions to check a hostname email or IP address against a
+ certificate. Add options x509 utility to print results of checks against
+ a certificate.
+ [Steve Henson]
+
+ *) Add -rev test option to s_server to just reverse order of characters
+ received by client and send back to server. Also prints an abbreviated
+ summary of the connection parameters.
+ [Steve Henson]
+
+ *) New option -brief for s_client and s_server to print out a brief summary
+ of connection parameters.
+ [Steve Henson]
+
+ *) Add functions to retrieve and manipulate the raw cipherlist sent by a
+ client to OpenSSL.
+ [Steve Henson]
+
+ *) New Suite B modes for TLS code. These use and enforce the requirements
+ of RFC6460: restrict ciphersuites, only permit Suite B algorithms and
+ only use Suite B curves. The Suite B modes can be set by using the
+ strings "SUITEB128", "SUITEB192" or "SUITEB128ONLY" for the cipherstring.
+ [Steve Henson]
+
+ *) New chain verification flags for Suite B levels of security. Check
+ algorithms are acceptable when flags are set in X509_verify_cert.
+ [Steve Henson]
+
+ *) Make tls1_check_chain return a set of flags indicating checks passed
+ by a certificate chain. Add additional tests to handle client
+ certificates: checks for matching certificate type and issuer name
+ comparison.
+ [Steve Henson]
+
+ *) If an attempt is made to use a signature algorithm not in the peer
+ preference list abort the handshake. If client has no suitable
+ signature algorithms in response to a certificate request do not
+ use the certificate.
+ [Steve Henson]
+
+ *) If server EC tmp key is not in client preference list abort handshake.
+ [Steve Henson]
+
+ *) Add support for certificate stores in CERT structure. This makes it
+ possible to have different stores per SSL structure or one store in
+ the parent SSL_CTX. Include distinct stores for certificate chain
+ verification and chain building. New ctrl SSL_CTRL_BUILD_CERT_CHAIN
+ to build and store a certificate chain in CERT structure: returning
+ an error if the chain cannot be built: this will allow applications
+ to test if a chain is correctly configured.
+
+ Note: if the CERT based stores are not set then the parent SSL_CTX
+ store is used to retain compatibility with existing behaviour.
+
+ [Steve Henson]
+
+ *) New function ssl_set_client_disabled to set a ciphersuite disabled
+ mask based on the current session, check mask when sending client
+ hello and checking the requested ciphersuite.
+ [Steve Henson]
+
+ *) New ctrls to retrieve and set certificate types in a certificate
+ request message. Print out received values in s_client. If certificate
+ types is not set with custom values set sensible values based on
+ supported signature algorithms.
+ [Steve Henson]
+
+ *) Support for distinct client and server supported signature algorithms.
+ [Steve Henson]
+
+ *) Add certificate callback. If set this is called whenever a certificate
+ is required by client or server. An application can decide which
+ certificate chain to present based on arbitrary criteria: for example
+ supported signature algorithms. Add very simple example to s_server.
+ This fixes many of the problems and restrictions of the existing client
+ certificate callback: for example you can now clear an existing
+ certificate and specify the whole chain.
+ [Steve Henson]
+
+ *) Add new "valid_flags" field to CERT_PKEY structure which determines what
+ the certificate can be used for (if anything). Set valid_flags field
+ in new tls1_check_chain function. Simplify ssl_set_cert_masks which used
+ to have similar checks in it.
+
+ Add new "cert_flags" field to CERT structure and include a "strict mode".
+ This enforces some TLS certificate requirements (such as only permitting
+ certificate signature algorithms contained in the supported algorithms
+ extension) which some implementations ignore: this option should be used
+ with caution as it could cause interoperability issues.
+ [Steve Henson]
+
+ *) Update and tidy signature algorithm extension processing. Work out
+ shared signature algorithms based on preferences and peer algorithms
+ and print them out in s_client and s_server. Abort handshake if no
+ shared signature algorithms.
+ [Steve Henson]
+
+ *) Add new functions to allow customised supported signature algorithms
+ for SSL and SSL_CTX structures. Add options to s_client and s_server
+ to support them.
+ [Steve Henson]
+
+ *) New function SSL_certs_clear() to delete all references to certificates
+ from an SSL structure. Before this once a certificate had been added
+ it couldn't be removed.
+ [Steve Henson]
+
+ *) Initial SSL tracing code. This parses out SSL/TLS records using the
+ message callback and prints the results. Needs compile time option
+ "enable-ssl-trace". New options to s_client and s_server to enable
+ tracing.
+ [Steve Henson]
+
+ *) New functions to retrieve certificate signature and signature
+ OID NID.
+ [Steve Henson]
+
+ *) Print out deprecated issuer and subject unique ID fields in
+ certificates.
[Steve Henson]
*) Update fips_test_suite to support multiple command line options. New
[Steve Henson]
*) Add functions FIPS_module_version() and FIPS_module_version_text()
- to return numberical and string versions of the FIPS module number.
+ to return numerical and string versions of the FIPS module number.
[Steve Henson]
*) Rename FIPS_mode_set and FIPS_mode to FIPS_module_mode_set and
- FIPS_module_mode. FIPS_mode and FIPS_mode_set will be implmeneted
+ FIPS_module_mode. FIPS_mode and FIPS_mode_set will be implemented
outside the validated module in the FIPS capable OpenSSL.
[Steve Henson]
*) Minor change to DRBG entropy callback semantics. In some cases
- there is no mutiple of the block length between min_len and
+ there is no multiple of the block length between min_len and
max_len. Allow the callback to return more than max_len bytes
of entropy but discard any extra: it is the callback's responsibility
to ensure that the extra data discarded does not impact the
is enable if DEBUG_UNUSED is set. Add to several functions in evp.h
whose return value is often ignored.

- Changes between 1.0.0f and 1.0.1 [xx XXX xxxx]
+
+ Changes between 1.0.1 and 1.0.2 [xx XXX xxxx]
+
+ *) MIPS assembly pack updates: support for MIPS32r2 and SmartMIPS ASE,
+ platform support for Linux and Android.
+ [Andy Polyakov]
+
+ *) Call OCSP Stapling callback after ciphersuite has been chosen, so
+ the right response is stapled. Also change current certificate to
+ the certificate actually sent.
+ See http://rt.openssl.org/Ticket/Display.html?id=2836.
+ [Rob Stradling <rob.stradling@comodo.com>]
+
+ *) Support for linux-x32, ILP32 environment in x86_64 framework.
+ [Andy Polyakov]
+
+ *) RFC 5878 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.
+ This means that the FIPS capable OpenSSL isn't forced to use the
+ (often lower performance) FIPS implementations outside FIPS mode.
+ [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]
+
+ *) 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]
+
+ *) 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]
+
+ *) 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]
+
+ Changes between 1.0.1c and 1.0.1d [xx XXX xxxx]
+
+ *) Fix possible deadlock when decoding public keys.
+ [Steve Henson]
+
+ *) Don't use TLS 1.0 record version number in initial client hello
+ if renegotiating.
+ [Steve Henson]
+
+ Changes between 1.0.1b and 1.0.1c [10 May 2012]
+
+ *) Sanity check record length before skipping explicit IV in TLS
+ 1.2, 1.1 and DTLS to avoid DoS attack.
+
+ Thanks to Codenomicon for discovering this issue using Fuzz-o-Matic
+ fuzzing as a service testing platform.
+ (CVE-2012-2333)
+ [Steve Henson]
+
+ *) Initialise tkeylen properly when encrypting CMS messages.
+ Thanks to Solar Designer of Openwall for reporting this issue.
+ [Steve Henson]
+
+ *) In FIPS mode don't try to use composite ciphers as they are not
+ approved.
+ [Steve Henson]
+
+ Changes between 1.0.1a and 1.0.1b [26 Apr 2012]
+
+ *) OpenSSL 1.0.0 sets SSL_OP_ALL to 0x80000FFFL and OpenSSL 1.0.1 and
+ 1.0.1a set SSL_OP_NO_TLSv1_1 to 0x00000400L which would unfortunately
+ mean any application compiled against OpenSSL 1.0.0 headers setting
+ SSL_OP_ALL would also set SSL_OP_NO_TLSv1_1, unintentionally disabling
+ TLS 1.1 also. Fix this by changing the value of SSL_OP_NO_TLSv1_1 to
+ 0x10000000L Any application which was previously compiled against
+ OpenSSL 1.0.1 or 1.0.1a headers and which cares about SSL_OP_NO_TLSv1_1
+ will need to be recompiled as a result. Letting be results in
+ inability to disable specifically TLS 1.1 and in client context,
+ in unlike event, limit maximum offered version to TLS 1.0 [see below].
+ [Steve Henson]
+
+ *) In order to ensure interoperability SSL_OP_NO_protocolX does not
+ disable just protocol X, but all protocols above X *if* there are
+ protocols *below* X still enabled. In more practical terms it means
+ that if application wants to disable TLS1.0 in favor of TLS1.1 and
+ above, it's not sufficient to pass SSL_OP_NO_TLSv1, one has to pass
+ SSL_OP_NO_TLSv1|SSL_OP_NO_SSLv3|SSL_OP_NO_SSLv2. This applies to
+ client side.
+ [Andy Polyakov]
+
+ Changes between 1.0.1 and 1.0.1a [19 Apr 2012]
+
+ *) Check for potentially exploitable overflows in asn1_d2i_read_bio
+ BUF_mem_grow and BUF_mem_grow_clean. Refuse attempts to shrink buffer
+ in CRYPTO_realloc_clean.
+
+ Thanks to Tavis Ormandy, Google Security Team, for discovering this
+ issue and to Adam Langley <agl@chromium.org> for fixing it.
+ (CVE-2012-2110)
+ [Adam Langley (Google), Tavis Ormandy, Google Security Team]
+
+ *) Don't allow TLS 1.2 SHA-256 ciphersuites in TLS 1.0, 1.1 connections.
+ [Adam Langley]
+
+ *) Workarounds for some broken servers that "hang" if a client hello
+ record length exceeds 255 bytes:
+
+ 1. Do not use record version number > TLS 1.0 in initial client
+ hello: some (but not all) hanging servers will now work.
+ 2. If we set OPENSSL_MAX_TLS1_2_CIPHER_LENGTH this will truncate
+ the number of ciphers sent in the client hello. This should be
+ set to an even number, such as 50, for example by passing:
+ -DOPENSSL_MAX_TLS1_2_CIPHER_LENGTH=50 to config or Configure.
+ Most broken servers should now work.
+ 3. If all else fails setting OPENSSL_NO_TLS1_2_CLIENT will disable
+ TLS 1.2 client support entirely.
+ [Steve Henson]
+
+ *) 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
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
+ encrypted premaster secret. As a workaround use the maximum permitted
client version in client hello, this should keep such servers happy
and still work with previous versions of OpenSSL.
[Steve Henson]
*) 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
+ RFC5289. Generalise some AES* cipherstrings to include GCM and
add a special AESGCM string for GCM only.
[Steve Henson]
[Steve Henson]
*) For FIPS capable OpenSSL interpret a NULL default public key method

- Changes between 1.0.0g and 1.0.0h [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)

new functions i2d_RSA_NET(), d2i_RSA_NET() etc which are the same
as the old Netscape_RSA functions except they have an additional
'sgckey' parameter which uses the modified algorithm. Also added
its own key.
