OpenSSL CHANGES
_______________
- Changes between 0.9.7c and 0.9.8 [xx XXX xxxx]
+ Changes between 0.9.8a and 0.9.9 [xx XXX xxxx]
+
+ *) Whirlpool hash implementation is added.
+ [Andy Polyakov]
+
+ *) BIGNUM code on 64-bit SPARCv9 targets is switched from bn(64,64) to
+ bn(64,32). Because of instruction set limitations it doesn't have
+ any negative impact on performance. This was done mostly in order
+ to make it possible to share assembler modules, such as bn_mul_mont
+ implementations, between 32- and 64-bit builds without hassle.
+ [Andy Polyakov]
+
+ *) Disable rogue ciphersuites:
+
+ - SSLv2 0x08 0x00 0x80 ("RC4-64-MD5")
+ - SSLv3/TLSv1 0x00 0x61 ("EXP1024-RC2-CBC-MD5")
+ - SSLv3/TLSv1 0x00 0x60 ("EXP1024-RC4-MD5")
+
+ The latter two were purportedly from
+ draft-ietf-tls-56-bit-ciphersuites-0[01].txt, but do not really
+ appear there.
+
+ Other ciphersuites from draft-ietf-tls-56-bit-ciphersuites-01.txt
+ remain enabled for now, but are just as unofficial, and the ID
+ has long expired; these will probably disappear soon.
+ [Bodo Moeller]
+
+ *) Move code previously exiled into file crypto/ec/ec2_smpt.c
+ to ec2_smpl.c, and no longer require the OPENSSL_EC_BIN_PT_COMP
+ macro.
+ [Bodo Moeller]
+
+ *) New candidate for BIGNUM assembler implementation, bn_mul_mont,
+ dedicated Montgomery multiplication procedure, is introduced.
+ BN_MONT_CTX is modified to allow bn_mul_mont to reach for higher
+ "64-bit" performance on certain 32-bit targets.
+ [Andy Polyakov]
+
+ *) New option SSL_OP_NO_COMP to disable use of compression selectively
+ in SSL structures. New SSL ctrl to set maximum send fragment size.
+ Save memory by seeting the I/O buffer sizes dynamically instead of
+ using the maximum available value.
+ [Steve Henson]
+
+ *) New option -V for 'openssl ciphers'. This prints the ciphersuite code
+ in addition to the text details.
+ [Bodo Moeller]
+
+ *) Very, very preliminary EXPERIMENTAL support for printing of general
+ ASN1 structures. This currently produces rather ugly output and doesn't
+ handle several customised structures at all.
+ [Steve Henson]
+
+ *) Integrated support for PVK file format and some related formats such
+ as MS PUBLICKEYBLOB and PRIVATEKEYBLOB. Command line switches to support
+ these in the 'rsa' and 'dsa' utilities.
+ [Steve Henson]
+
+ *) Support for PKCS#1 RSAPublicKey format on rsa utility command line.
+ [Steve Henson]
+
+ *) Remove the ancient ASN1_METHOD code. This was only ever used in one
+ place for the (very old) "NETSCAPE" format certificates which are now
+ handled using new ASN1 code equivalents.
+ [Steve Henson]
+
+ *) Let the TLSv1_method() etc. functions return a 'const' SSL_METHOD
+ pointer and make the SSL_METHOD parameter in SSL_CTX_new,
+ SSL_CTX_set_ssl_version and SSL_set_ssl_method 'const'.
+ [Nils Larsch]
+
+ *) Modify CRL distribution points extension code to print out previously
+ unsupported fields. Enhance extension setting code to allow setting of
+ all fields.
+ [Steve Henson]
+
+ *) Add print and set support for Issuing Distribution Point CRL extension.
+ [Steve Henson]
+
+ Changes between 0.9.8a and 0.9.8b [XX xxx XXXX]
+
+ *) Update support for ECC-based TLS ciphersuites according to
+ draft-ietf-tls-ecc-12.txt with proposed changes.
+ [Douglas Stebila]
+
+ *) New functions EVP_CIPHER_CTX_new() and EVP_CIPHER_CTX_free() to support
+ opaque EVP_CIPHER_CTX handling.
+ [Steve Henson]
+
+ *) Fixes and enhancements to zlib compression code. We now only use
+ "zlib1.dll" and use the default __cdecl calling convention on Win32
+ to conform with the standards mentioned here:
+ http://www.zlib.net/DLL_FAQ.txt
+ Static zlib linking now works on Windows and the new --with-zlib-include
+ --with-zlib-lib options to Configure can be used to supply the location
+ of the headers and library. Gracefully handle case where zlib library
+ can't be loaded.
+ [Steve Henson]
+
+ *) Several fixes and enhancements to the OID generation code. The old code
+ sometimes allowed invalid OIDs (1.X for X >= 40 for example), couldn't
+ handle numbers larger than ULONG_MAX, truncated printing and had a
+ non standard OBJ_obj2txt() behaviour.
+ [Steve Henson]
+
+ *) Add support for building of engines under engine/ as shared libraries
+ under VC++ build system.
+ [Steve Henson]
+
+ *) Corrected the numerous bugs in the Win32 path splitter in DSO.
+ Hopefully, we will not see any false combination of paths any more.
+ [Richard Levitte]
+
+ Changes between 0.9.8 and 0.9.8a [11 Oct 2005]
+
+ *) Remove the functionality of SSL_OP_MSIE_SSLV2_RSA_PADDING
+ (part of SSL_OP_ALL). This option used to disable the
+ countermeasure against man-in-the-middle protocol-version
+ rollback in the SSL 2.0 server implementation, which is a bad
+ idea. (CVE-2005-2969)
+
+ [Bodo Moeller; problem pointed out by Yutaka Oiwa (Research Center
+ for Information Security, National Institute of Advanced Industrial
+ Science and Technology [AIST], Japan)]
+
+ *) Add two function to clear and return the verify parameter flags.
+ [Steve Henson]
+
+ *) Keep cipherlists sorted in the source instead of sorting them at
+ runtime, thus removing the need for a lock.
+ [Nils Larsch]
+
+ *) Avoid some small subgroup attacks in Diffie-Hellman.
+ [Nick Mathewson and Ben Laurie]
+
+ *) Add functions for well-known primes.
+ [Nick Mathewson]
+
+ *) Extended Windows CE support.
+ [Satoshi Nakamura and Andy Polyakov]
+
+ *) Initialize SSL_METHOD structures at compile time instead of during
+ runtime, thus removing the need for a lock.
+ [Steve Henson]
+
+ *) Make PKCS7_decrypt() work even if no certificate is supplied by
+ attempting to decrypt each encrypted key in turn. Add support to
+ smime utility.
+ [Steve Henson]
+
+ Changes between 0.9.7h and 0.9.8 [05 Jul 2005]
+
+ *) Add libcrypto.pc and libssl.pc for those who feel they need them.
+ [Richard Levitte]
+
+ *) Change CA.sh and CA.pl so they don't bundle the CSR and the private
+ key into the same file any more.
+ [Richard Levitte]
+
+ *) Add initial support for Win64, both IA64 and AMD64/x64 flavors.
+ [Andy Polyakov]
+
+ *) Add -utf8 command line and config file option to 'ca'.
+ [Stefan <stf@udoma.org]
+
+ *) Removed the macro des_crypt(), as it seems to conflict with some
+ libraries. Use DES_crypt().
+ [Richard Levitte]
+
+ *) Correct naming of the 'chil' and '4758cca' ENGINEs. This
+ involves renaming the source and generated shared-libs for
+ both. The engines will accept the corrected or legacy ids
+ ('ncipher' and '4758_cca' respectively) when binding. NB,
+ this only applies when building 'shared'.
+ [Corinna Vinschen <vinschen@redhat.com> and Geoff Thorpe]
+
+ *) Add attribute functions to EVP_PKEY structure. Modify
+ PKCS12_create() to recognize a CSP name attribute and
+ use it. Make -CSP option work again in pkcs12 utility.
+ [Steve Henson]
+
+ *) Add new functionality to the bn blinding code:
+ - automatic re-creation of the BN_BLINDING parameters after
+ a fixed number of uses (currently 32)
+ - add new function for parameter creation
+ - introduce flags to control the update behaviour of the
+ BN_BLINDING parameters
+ - hide BN_BLINDING structure
+ Add a second BN_BLINDING slot to the RSA structure to improve
+ performance when a single RSA object is shared among several
+ threads.
+ [Nils Larsch]
+
+ *) Add support for DTLS.
+ [Nagendra Modadugu <nagendra@cs.stanford.edu> and Ben Laurie]
+
+ *) Add support for DER encoded private keys (SSL_FILETYPE_ASN1)
+ to SSL_CTX_use_PrivateKey_file() and SSL_use_PrivateKey_file()
+ [Walter Goulet]
+
+ *) Remove buggy and incompletet DH cert support from
+ ssl/ssl_rsa.c and ssl/s3_both.c
+ [Nils Larsch]
+
+ *) Use SHA-1 instead of MD5 as the default digest algorithm for
+ the apps/openssl applications.
+ [Nils Larsch]
+
+ *) Compile clean with "-Wall -Wmissing-prototypes
+ -Wstrict-prototypes -Wmissing-declarations -Werror". Currently
+ DEBUG_SAFESTACK must also be set.
+ [Ben Laurie]
+
+ *) Change ./Configure so that certain algorithms can be disabled by default.
+ The new counterpiece to "no-xxx" is "enable-xxx".
+
+ The patented RC5 and MDC2 algorithms will now be disabled unless
+ "enable-rc5" and "enable-mdc2", respectively, are specified.
+
+ (IDEA remains enabled despite being patented. This is because IDEA
+ is frequently required for interoperability, and there is no license
+ fee for non-commercial use. As before, "no-idea" can be used to
+ avoid this algorithm.)
+
+ [Bodo Moeller]
+
+ *) Add processing of proxy certificates (see RFC 3820). This work was
+ sponsored by KTH (The Royal Institute of Technology in Stockholm) and
+ EGEE (Enabling Grids for E-science in Europe).
+ [Richard Levitte]
+
+ *) RC4 performance overhaul on modern architectures/implementations, such
+ as Intel P4, IA-64 and AMD64.
+ [Andy Polyakov]
+
+ *) New utility extract-section.pl. This can be used specify an alternative
+ section number in a pod file instead of having to treat each file as
+ a separate case in Makefile. This can be done by adding two lines to the
+ pod file:
+
+ =for comment openssl_section:XXX
+
+ The blank line is mandatory.
+
+ [Steve Henson]
+
+ *) New arguments -certform, -keyform and -pass for s_client and s_server
+ to allow alternative format key and certificate files and passphrase
+ sources.
+ [Steve Henson]
+
+ *) New structure X509_VERIFY_PARAM which combines current verify parameters,
+ update associated structures and add various utility functions.
+
+ Add new policy related verify parameters, include policy checking in
+ standard verify code. Enhance 'smime' application with extra parameters
+ to support policy checking and print out.
+ [Steve Henson]
+
+ *) Add a new engine to support VIA PadLock ACE extensions in the VIA C3
+ Nehemiah processors. These extensions support AES encryption in hardware
+ as well as RNG (though RNG support is currently disabled).
+ [Michal Ludvig <michal@logix.cz>, with help from Andy Polyakov]
+
+ *) Deprecate BN_[get|set]_params() functions (they were ignored internally).
+ [Geoff Thorpe]
+
+ *) New FIPS 180-2 algorithms, SHA-224/-256/-384/-512 are implemented.
+ [Andy Polyakov and a number of other people]
+
+ *) Improved PowerPC platform support. Most notably BIGNUM assembler
+ implementation contributed by IBM.
+ [Suresh Chari, Peter Waltenberg, Andy Polyakov]
+
+ *) The new 'RSA_generate_key_ex' function now takes a BIGNUM for the public
+ exponent rather than 'unsigned long'. There is a corresponding change to
+ the new 'rsa_keygen' element of the RSA_METHOD structure.
+ [Jelte Jansen, Geoff Thorpe]
+
+ *) Functionality for creating the initial serial number file is now
+ moved from CA.pl to the 'ca' utility with a new option -create_serial.
+
+ (Before OpenSSL 0.9.7e, CA.pl used to initialize the serial
+ number file to 1, which is bound to cause problems. To avoid
+ the problems while respecting compatibility between different 0.9.7
+ patchlevels, 0.9.7e employed 'openssl x509 -next_serial' in
+ CA.pl for serial number initialization. With the new release 0.9.8,
+ we can fix the problem directly in the 'ca' utility.)
+ [Steve Henson]
+
+ *) Reduced header interdepencies by declaring more opaque objects in
+ ossl_typ.h. As a consequence, including some headers (eg. engine.h) will
+ give fewer recursive includes, which could break lazy source code - so
+ this change is covered by the OPENSSL_NO_DEPRECATED symbol. As always,
+ developers should define this symbol when building and using openssl to
+ ensure they track the recommended behaviour, interfaces, [etc], but
+ backwards-compatible behaviour prevails when this isn't defined.
+ [Geoff Thorpe]
+
+ *) New function X509_POLICY_NODE_print() which prints out policy nodes.
+ [Steve Henson]
+
+ *) Add new EVP function EVP_CIPHER_CTX_rand_key and associated functionality.
+ This will generate a random key of the appropriate length based on the
+ cipher context. The EVP_CIPHER can provide its own random key generation
+ routine to support keys of a specific form. This is used in the des and
+ 3des routines to generate a key of the correct parity. Update S/MIME
+ code to use new functions and hence generate correct parity DES keys.
+ Add EVP_CHECK_DES_KEY #define to return an error if the key is not
+ valid (weak or incorrect parity).
+ [Steve Henson]
+
+ *) Add a local set of CRLs that can be used by X509_verify_cert() as well
+ as looking them up. This is useful when the verified structure may contain
+ CRLs, for example PKCS#7 signedData. Modify PKCS7_verify() to use any CRLs
+ present unless the new PKCS7_NO_CRL flag is asserted.
+ [Steve Henson]
+
+ *) Extend ASN1 oid configuration module. It now additionally accepts the
+ syntax:
+
+ shortName = some long name, 1.2.3.4
+ [Steve Henson]
+
+ *) Reimplemented the BN_CTX implementation. There is now no more static
+ limitation on the number of variables it can handle nor the depth of the
+ "stack" handling for BN_CTX_start()/BN_CTX_end() pairs. The stack
+ information can now expand as required, and rather than having a single
+ static array of bignums, BN_CTX now uses a linked-list of such arrays
+ allowing it to expand on demand whilst maintaining the usefulness of
+ BN_CTX's "bundling".
+ [Geoff Thorpe]
+
+ *) Add a missing BN_CTX parameter to the 'rsa_mod_exp' callback in RSA_METHOD
+ to allow all RSA operations to function using a single BN_CTX.
+ [Geoff Thorpe]
+
+ *) Preliminary support for certificate policy evaluation and checking. This
+ is initially intended to pass the tests outlined in "Conformance Testing
+ of Relying Party Client Certificate Path Processing Logic" v1.07.
+ [Steve Henson]
+
+ *) bn_dup_expand() has been deprecated, it was introduced in 0.9.7 and
+ remained unused and not that useful. A variety of other little bignum
+ tweaks and fixes have also been made continuing on from the audit (see
+ below).
+ [Geoff Thorpe]
+
+ *) Constify all or almost all d2i, c2i, s2i and r2i functions, along with
+ associated ASN1, EVP and SSL functions and old ASN1 macros.
+ [Richard Levitte]
*) BN_zero() only needs to set 'top' and 'neg' to zero for correct results,
and this should never fail. So the return value from the use of
*) Support for policyMappings certificate extension.
[Steve Henson]
- *) Fixed a typo bug that would cause ENGINE_set_default() to set an
- ENGINE as defaults for all supported algorithms irrespective of
- the 'flags' parameter. 'flags' is now honoured, so applications
- should make sure they are passing it correctly.
- [Geoff Thorpe]
-
*) Make sure the default DSA_METHOD implementation only uses its
dsa_mod_exp() and/or bn_mod_exp() handlers if they are non-NULL,
and change its own handlers to be NULL so as to remove unnecessary
Makefile.shared, for Cygwin's sake.
[Richard Levitte]
- *) Extend the BIGNUM API by creating new macros that behave like
- functions
-
- void BN_set_sign(BIGNUM *a, int neg);
- int BN_get_sign(const BIGNUM *a);
+ *) Extend the BIGNUM API by creating a function
+ void BN_set_negative(BIGNUM *a, int neg);
+ and a macro that behave like
+ int BN_is_negative(const BIGNUM *a);
- and avoid the need to access 'a->neg' directly in applications.
- [Nils Larsch <nla@trustcenter.de>]
+ to avoid the need to access 'a->neg' directly in applications.
+ [Nils Larsch]
*) Implement fast modular reduction for pseudo-Mersenne primes
used in NIST curves (crypto/bn/bn_nist.c, crypto/ec/ecp_nist.c).
*) Include some named elliptic curves, and add OIDs from X9.62,
SECG, and WAP/WTLS. Each curve can be obtained from the new
function
- EC_GROUP_new_by_nid(),
+ EC_GROUP_new_by_curve_name(),
and the list of available named curves can be obtained with
EC_get_builtin_curves().
Also add a 'curve_name' member to EC_GROUP objects, which can be
accessed via
- EC_GROUP_set_nid()
- EC_GROUP_get_nid()
- [Nils Larsch <nla@trustcenter.de, Bodo Moeller]
+ EC_GROUP_set_curve_name()
+ EC_GROUP_get_curve_name()
+ [Nils Larsch <larsch@trustcenter.de, Bodo Moeller]
*) Remove a few calls to bn_wexpand() in BN_sqr() (the one in there
was actually never needed) and in BN_mul(). The removal in BN_mul()
differing sizes.
[Richard Levitte]
- Changes between 0.9.7c and 0.9.7d [xx XXX XXXX]
+ Changes between 0.9.7h and 0.9.7i [14 Oct 2005]
+
+ *) Wrapped the definition of EVP_MAX_MD_SIZE in a #ifdef OPENSSL_FIPS.
+ The value now differs depending on if you build for FIPS or not.
+ BEWARE! A program linked with a shared FIPSed libcrypto can't be
+ safely run with a non-FIPSed libcrypto, as it may crash because of
+ the difference induced by this change.
+ [Andy Polyakov]
+
+ Changes between 0.9.7g and 0.9.7h [11 Oct 2005]
+
+ *) Remove the functionality of SSL_OP_MSIE_SSLV2_RSA_PADDING
+ (part of SSL_OP_ALL). This option used to disable the
+ countermeasure against man-in-the-middle protocol-version
+ rollback in the SSL 2.0 server implementation, which is a bad
+ idea. (CVE-2005-2969)
+
+ [Bodo Moeller; problem pointed out by Yutaka Oiwa (Research Center
+ for Information Security, National Institute of Advanced Industrial
+ Science and Technology [AIST], Japan)]
+
+ *) Minimal support for X9.31 signatures and PSS padding modes. This is
+ mainly for FIPS compliance and not fully integrated at this stage.
+ [Steve Henson]
+
+ *) For DSA signing, unless DSA_FLAG_NO_EXP_CONSTTIME is set, perform
+ the exponentiation using a fixed-length exponent. (Otherwise,
+ the information leaked through timing could expose the secret key
+ after many signatures; cf. Bleichenbacher's attack on DSA with
+ biased k.)
+ [Bodo Moeller]
+
+ *) Make a new fixed-window mod_exp implementation the default for
+ RSA, DSA, and DH private-key operations so that the sequence of
+ squares and multiplies and the memory access pattern are
+ independent of the particular secret key. This will mitigate
+ cache-timing and potential related attacks.
+
+ BN_mod_exp_mont_consttime() is the new exponentiation implementation,
+ and this is automatically used by BN_mod_exp_mont() if the new flag
+ BN_FLG_EXP_CONSTTIME is set for the exponent. RSA, DSA, and DH
+ will use this BN flag for private exponents unless the flag
+ RSA_FLAG_NO_EXP_CONSTTIME, DSA_FLAG_NO_EXP_CONSTTIME, or
+ DH_FLAG_NO_EXP_CONSTTIME, respectively, is set.
+
+ [Matthew D Wood (Intel Corp), with some changes by Bodo Moeller]
+
+ *) Change the client implementation for SSLv23_method() and
+ SSLv23_client_method() so that is uses the SSL 3.0/TLS 1.0
+ Client Hello message format if the SSL_OP_NO_SSLv2 option is set.
+ (Previously, the SSL 2.0 backwards compatible Client Hello
+ message format would be used even with SSL_OP_NO_SSLv2.)
+ [Bodo Moeller]
+
+ *) Add support for smime-type MIME parameter in S/MIME messages which some
+ clients need.
+ [Steve Henson]
+
+ *) New function BN_MONT_CTX_set_locked() to set montgomery parameters in
+ a threadsafe manner. Modify rsa code to use new function and add calls
+ to dsa and dh code (which had race conditions before).
+ [Steve Henson]
+
+ *) Include the fixed error library code in the C error file definitions
+ instead of fixing them up at runtime. This keeps the error code
+ structures constant.
+ [Steve Henson]
+
+ Changes between 0.9.7f and 0.9.7g [11 Apr 2005]
+
+ [NB: OpenSSL 0.9.7h and later 0.9.7 patch levels were released after
+ OpenSSL 0.9.8.]
+
+ *) Fixes for newer kerberos headers. NB: the casts are needed because
+ the 'length' field is signed on one version and unsigned on another
+ with no (?) obvious way to tell the difference, without these VC++
+ complains. Also the "definition" of FAR (blank) is no longer included
+ nor is the error ENOMEM. KRB5_PRIVATE has to be set to 1 to pick up
+ some needed definitions.
+ [Steve Henson]
+
+ *) Undo Cygwin change.
+ [Ulf Möller]
+
+ *) Added support for proxy certificates according to RFC 3820.
+ Because they may be a security thread to unaware applications,
+ they must be explicitely allowed in run-time. See
+ docs/HOWTO/proxy_certificates.txt for further information.
+ [Richard Levitte]
+
+ Changes between 0.9.7e and 0.9.7f [22 Mar 2005]
+
+ *) Use (SSL_RANDOM_VALUE - 4) bytes of pseudo random data when generating
+ server and client random values. Previously
+ (SSL_RANDOM_VALUE - sizeof(time_t)) would be used which would result in
+ less random data when sizeof(time_t) > 4 (some 64 bit platforms).
+
+ This change has negligible security impact because:
+
+ 1. Server and client random values still have 24 bytes of pseudo random
+ data.
+
+ 2. Server and client random values are sent in the clear in the initial
+ handshake.
+
+ 3. The master secret is derived using the premaster secret (48 bytes in
+ size for static RSA ciphersuites) as well as client server and random
+ values.
+
+ The OpenSSL team would like to thank the UK NISCC for bringing this issue
+ to our attention.
+
+ [Stephen Henson, reported by UK NISCC]
+
+ *) Use Windows randomness collection on Cygwin.
+ [Ulf Möller]
+
+ *) Fix hang in EGD/PRNGD query when communication socket is closed
+ prematurely by EGD/PRNGD.
+ [Darren Tucker <dtucker@zip.com.au> via Lutz Jänicke, resolves #1014]
+
+ *) Prompt for pass phrases when appropriate for PKCS12 input format.
+ [Steve Henson]
+
+ *) Back-port of selected performance improvements from development
+ branch, as well as improved support for PowerPC platforms.
+ [Andy Polyakov]
+
+ *) Add lots of checks for memory allocation failure, error codes to indicate
+ failure and freeing up memory if a failure occurs.
+ [Nauticus Networks SSL Team <openssl@nauticusnet.com>, Steve Henson]
+
+ *) Add new -passin argument to dgst.
+ [Steve Henson]
+
+ *) Perform some character comparisons of different types in X509_NAME_cmp:
+ this is needed for some certificates that reencode DNs into UTF8Strings
+ (in violation of RFC3280) and can't or wont issue name rollover
+ certificates.
+ [Steve Henson]
+
+ *) Make an explicit check during certificate validation to see that
+ the CA setting in each certificate on the chain is correct. As a
+ side effect always do the following basic checks on extensions,
+ not just when there's an associated purpose to the check:
+
+ - if there is an unhandled critical extension (unless the user
+ has chosen to ignore this fault)
+ - if the path length has been exceeded (if one is set at all)
+ - that certain extensions fit the associated purpose (if one has
+ been given)
+ [Richard Levitte]
+
+ Changes between 0.9.7d and 0.9.7e [25 Oct 2004]
+
+ *) Avoid a race condition when CRLs are checked in a multi threaded
+ environment. This would happen due to the reordering of the revoked
+ entries during signature checking and serial number lookup. Now the
+ encoding is cached and the serial number sort performed under a lock.
+ Add new STACK function sk_is_sorted().
+ [Steve Henson]
+
+ *) Add Delta CRL to the extension code.
+ [Steve Henson]
+
+ *) Various fixes to s3_pkt.c so alerts are sent properly.
+ [David Holmes <d.holmes@f5.com>]
+
+ *) Reduce the chances of duplicate issuer name and serial numbers (in
+ violation of RFC3280) using the OpenSSL certificate creation utilities.
+ This is done by creating a random 64 bit value for the initial serial
+ number when a serial number file is created or when a self signed
+ certificate is created using 'openssl req -x509'. The initial serial
+ number file is created using 'openssl x509 -next_serial' in CA.pl
+ rather than being initialized to 1.
+ [Steve Henson]
+
+ Changes between 0.9.7c and 0.9.7d [17 Mar 2004]
+
+ *) Fix null-pointer assignment in do_change_cipher_spec() revealed
+ by using the Codenomicon TLS Test Tool (CVE-2004-0079)
+ [Joe Orton, Steve Henson]
+
+ *) Fix flaw in SSL/TLS handshaking when using Kerberos ciphersuites
+ (CVE-2004-0112)
+ [Joe Orton, Steve Henson]
+
+ *) Make it possible to have multiple active certificates with the same
+ subject in the CA index file. This is done only if the keyword
+ 'unique_subject' is set to 'no' in the main CA section (default
+ if 'CA_default') of the configuration file. The value is saved
+ with the database itself in a separate index attribute file,
+ named like the index file with '.attr' appended to the name.
+ [Richard Levitte]
*) X509 verify fixes. Disable broken certificate workarounds when
X509_V_FLAGS_X509_STRICT is set. Check CRL issuer has cRLSign set if
*) Fix various bugs revealed by running the NISCC test suite:
Stop out of bounds reads in the ASN1 code when presented with
- invalid tags (CAN-2003-0543 and CAN-2003-0544).
+ invalid tags (CVE-2003-0543 and CVE-2003-0544).
- Free up ASN1_TYPE correctly if ANY type is invalid (CAN-2003-0545).
+ Free up ASN1_TYPE correctly if ANY type is invalid (CVE-2003-0545).
If verify callback ignores invalid public key errors don't try to check
certificate signature with the NULL public key.

-- Geoff's ENGINE_set_default() fix
+ *) Fixed a typo bug that would cause ENGINE_set_default() to set an
+ ENGINE as defaults for all supported algorithms irrespective of

*) Target "mingw" now allows native Windows code to be generated in
