OpenSSL CHANGES
_______________
- Changes between 0.9.7c and 0.9.8 [xx XXX xxxx]
+ Changes between 0.9.7e and 0.9.8 [xx XXX xxxx]
+
+ *) 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]
- *) 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 now moved from CA.pl to the 'ca' utility with a new
- option -create_serial.
+ *) 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
*) 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
differing sizes.
[Richard Levitte]
- Changes between 0.9.7c and 0.9.7d [xx XXX XXXX]
+ Changes between 0.9.7e and 0.9.7f [XX xxx XXXX]
+
+ *) Prompt for pass phrases when appropriate for PKCS12 input format.
+ [Steve Henson]
+
+ *) 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 (CAN-2004-0079)
+ [Joe Orton, Steve Henson]
+
+ *) Fix flaw in SSL/TLS handshaking when using Kerberos ciphersuites
+ (CAN-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
between threads, blinding will still be very fast).
[Bodo Moeller]
+ *) 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]
+
*) Target "mingw" now allows native Windows code to be generated in
the Cygwin environment as well as with the MinGW compiler.
[Ulf Moeller]
*) Clean old EAY MD5 hack from e_os.h.
[Richard Levitte]
- Changes between 0.9.6j and 0.9.6k [30 Sep 2003]
+ Changes between 0.9.6l and 0.9.6m [17 Mar 2004]
- *) Fix various bugs revealed by running the NISCC test suite:
+ *) Fix null-pointer assignment in do_change_cipher_spec() revealed
+ by using the Codenomicon TLS Test Tool (CAN-2004-0079)
+ [Joe Orton, Steve Henson]
- Stop out of bounds reads in the ASN1 code when presented with
- invalid tags (CAN-2003-0543 and CAN-2003-0544).
-
- If verify callback ignores invalid public key errors don't try to check
- certificate signature with the NULL public key.
+ Changes between 0.9.6k and 0.9.6l [04 Nov 2003]
+
+ *) Fix additional bug revealed by the NISCC test suite:
+ Stop bug triggering large recursion when presented with
+ certain ASN.1 tags (CAN-2003-0851)
