* Version 2.8.2 (released 2009-08-10)
** libgnutls: Fix problem with NUL bytes in X.509 CN and SAN fields.
By using a NUL byte in CN/SAN fields, it was possible to fool GnuTLS
into 1) not printing the entire CN/SAN field value when printing a
certificate and 2) cause incorrect positive matches when matching a
hostname against a certificate. Some CAs apparently have poor
checking of CN/SAN values and issue these (arguable invalid)
certificates. Combined, this can be used by attackers to become a
MITM on server-authenticated TLS sessions. The problem is mitigated
since attackers needs to get one certificate per site they want to
attack, and the attacker reveals his tracks by applying for a
certificate at the CA. It does not apply to client authenticated TLS
sessions. Research presented independently by Dan Kaminsky and Moxie
Marlinspike at BlackHat09. Thanks to Tomas Hoger <thoger@redhat.com>
for providing one part of the patch. [GNUTLS-SA-2009-4].

*** API/ABI changes in GnuTLS 2.8 compared to GnuTLS 2.6.x
No offically supported interfaces have been modified or removed. The
library should be completely backwards compatible on both the source
and binary level.
The shared library no longer exports some symbols that have never been
officially supported, i.e., not mentioned in any of the header files.
The symbols are:
_gnutls*
gnutls_asn1_tab
Normally when symbols are removed, the shared library version has to
be incremented. This leads to a significant cost for everyone using
the library. Because none of the above symbols have ever been
intended for use by well-behaved applications, we decided that the it
would be better for those applications to pay the price rather than
incurring problems on the majority of applications.
If it turns out that applications have been using unofficial
interfaces, we will need to release a follow-on release on the v2.8
branch to exports additional interfaces. However, initial testing
suggests that few if any applications have been using any of the
internal symbols.
Although not a new change compared to 2.6.x, we'd like to remind you
interfaces have been modified so that X.509 chain verification now
also checks activation/expiration times on certificates. The affected
functions are:
gnutls_x509_crt_list_verify: CHANGED, checks activation/expiration times.
gnutls_certificate_verify_peers: Likewise.
gnutls_certificate_verify_peers2: Likewise.
GNUTLS_CERT_NOT_ACTIVATED: ADDED.
GNUTLS_CERT_EXPIRED: ADDED.
GNUTLS_VERIFY_DISABLE_TIME_CHECKS: ADDED.
This change in behaviour was made during the GnuTLS 2.6.x cycle, and
we gave our rationale for it in earlier release notes.
The following symbols have been added to the library:
gnutls_certificate_set_x509_simple_pkcs12_mem: ADDED
gnutls_x509_crl_get_authority_key_id: ADDED
gnutls_x509_crl_get_extension_data: ADDED
gnutls_x509_crl_get_extension_info: ADDED
gnutls_x509_crl_get_extension_oid: ADDED
gnutls_x509_crl_get_number: ADDED
gnutls_x509_crl_set_authority_key_id: ADDED
gnutls_x509_crl_set_number: ADDED
gnutls_x509_crq_get_attribute_data: ADDED
gnutls_x509_crq_get_attribute_info: ADDED
gnutls_x509_crq_get_basic_constraints: ADDED
gnutls_x509_crq_get_extension_by_oid: ADDED
gnutls_x509_crq_get_extension_data: ADDED
gnutls_x509_crq_get_extension_info: ADDED

The following interfaces have been added to the header files:
GNUTLS_VERSION: ADDED, replaces LIBGNUTLS_VERSION.
GNUTLS_VERSION_MAJOR: ADDED, replaces LIBGNUTLS_VERSION_MAJOR.

Merged from stable branch. [GNUTLS-SA-2009-2] [CVE-2009-1416]
** libgnutls: Check expiration/activation time on untrusted certificates.
Merged from stable branch. Reported by Romain Francoise
<romain@orebokech.com>. This changes the semantics of
gnutls_x509_crt_list_verify, which in turn is used by
gnutls_certificate_verify_peers and gnutls_certificate_verify_peers2.
We add two new gnutls_certificate_status_t codes for reporting the new
error condition, GNUTLS_CERT_NOT_ACTIVATED and GNUTLS_CERT_EXPIRED.
We also add a new gnutls_certificate_verify_flags flag,
GNUTLS_VERIFY_DISABLE_TIME_CHECKS, that can be used to disable the new
behaviour. [GNUTLS-SA-2009-3] [CVE-2009-1417]
** lib: Linker version scripts reduces number of exported symbols.
The linker version script now lists all exported ABIs explicitly, to
avoid accidentally exporting unintended functions. Compared to
before, most symbols beginning with _gnutls* are no longer exported.
These functions have never been intended for use by applications, and
there were no prototypes for these function in the public header
files. Thus we believe it is possible to do this without incrementing
the library ABI version which normally has to be done when removing an
interface.
** lib: Limit exported symbols on systems without LD linker scripts.
Before all symbols were exported. Now we limit the exported symbols
to (for libgnutls and libgnutls-extra) gnutls* and (for libgnutls)
_gnutls*. This is a superset of the actual supported ABI, but still
an improvement compared to before. This is implemented using Libtool
-export-symbols-regex. It is more portable than linker version
scripts.
** libgnutls: Incremented CURRENT/AGE libtool version to reflect new symbols.
This should have been done in the last release.
** gnutls-serv: Listen on all interfaces, including both IPv4 and IPv6.
Reported by Peter Hendrickson <pdh@wiredyne.com> in
<http://thread.gmane.org/gmane.comp.encryption.gpg.gnutls.devel/3476>.
** doc: Improved sections for the info manual.
We now follow the advice given by the texinfo manual on which
directory categories to use. In particular, libgnutls moved from the
'GNU Libraries' section to the 'Software libraries' and the command
line tools moved from 'Network Applications' to 'System
Administration'.
** API and ABI modifications:
gnutls_x509_crt_list_verify: CHANGED, checks activation/expiration times.
gnutls_certificate_verify_peers: Likewise.
gnutls_certificate_verify_peers2: Likewise.
GNUTLS_CERT_NOT_ACTIVATED: ADDED.
GNUTLS_CERT_EXPIRED: ADDED.
GNUTLS_VERIFY_DISABLE_TIME_CHECKS: ADDED.
* Version 2.7.7 (released 2009-04-20)
** libgnutls: Applied patch by Cedric Bail to add functions
gnutls_x509_crt_verify_hash() and gnutls_x509_crt_get_verify_algorithm().
** gnutls.pc: Add -ltasn1 to 'pkg-config --libs --static gnutls' output.

** API and ABI modifications:
gnutls_x509_crt_verify_hash: ADDED

* Version 2.7.6 (released 2009-02-27)
** certtool: Query for multiple dnsName subjectAltName in interactive mode.
This applies both to generating certificates and certificate requests.
** pkix.asn: Removed unneeded definitions to reduce memory usage.
** gnutls-cli: No longer accepts V1 CAs by default during X.509 chain verify.
Use --priority NORMAL:%VERIFY_ALLOW_X509_V1_CA_CRT to permit V1 CAs to
be used for chain verification.
** gnutls-serv: No longer disable MAC padding by default.
Use --priority NORMAL:%COMPAT to disable MAC padding again.
** gnutls-cli: Certificate information output format changed.
The tool now uses libgnutls' functions to print certificate
information. This avoids code duplication.
** libgnutls: New priority strings %VERIFY_ALLOW_SIGN_RSA_MD5
** and %VERIFY_ALLOW_X509_V1_CA_CRT.
They can be used to override the default certificate chain validation
behaviour.
** libgnutls: Added %SSL3_RECORD_VERSION priority string that allows to
specify the client hello message record version. Used to overcome buggy
TLS servers. Report by Martin von Gagern.
** libgnutls: gnutls_x509_crt_print prints signature algorithm in oneline mode.
** libgnutls: gnutls_openpgp_crt_print supports oneline mode.
** doc: Update gnutls-cli and gnutls-serv --help output descriptions.
** API and ABI modifications:
No changes since last version.
* Version 2.7.5 (released 2009-02-06)
** libgnutls: Accept chains where intermediary certs are trusted.
Before GnuTLS needed to validate the entire chain back to a
self-signed certificate. GnuTLS will now stop looking when it has
found an intermediary trusted certificate. The new behaviour is
useful when chains, for example, contains a top-level CA, an
intermediary CA signed using RSA-MD5, and an end-entity certificate.
To avoid chain validation errors due to the RSA-MD5 cert, you can
explicitly add the intermediary RSA-MD5 cert to your trusted certs.
The signature on trusted certificates are not checked, so the chain
has a chance to validate correctly. Reported by "Douglas E. Engert"

** libgnutls: Permit V1 Certificate Authorities properly.
Before they were mistakenly rejected even though
GNUTLS_VERIFY_ALLOW_ANY_X509_V1_CA_CRT and/or
GNUTLS_VERIFY_ALLOW_X509_V1_CA_CRT were supplied. Reported by
"Douglas E. Engert" <deengert@anl.gov> in
<http://thread.gmane.org/gmane.comp.encryption.gpg.gnutls.devel/3351>.
** API and ABI modifications:
No changes since last version.
* Version 2.7.4 (released 2009-01-07)
** libgnutls: deprecate X.509 validation chains using MD5 and MD2 signatures.
This is a bugfix -- the previous attempt to do this from internal x509
certificate verification procedures did not return the correct value
for certificates using a weak hash. Reported by Daniel Kahn Gillmor
<dkg@fifthhorseman.net> in
<http://thread.gmane.org/gmane.comp.encryption.gpg.gnutls.devel/3332>,
debugged and patch by Tomas Mraz <tmraz@redhat.com> and Daniel Kahn
Gillmor <dkg@fifthhorseman.net>.
** libgnutls: New interface to get key id for certificate requests.
Patch from David Marín Carreño <davefx@gmail.com> in
<http://thread.gmane.org/gmane.comp.encryption.gpg.gnutls.devel/3321>.
** libgnutls: gnutls_x509_crq_print will now also print public key id.
** certtool: --verify-chain now prints results of using library verification.
Earlier, certtool --verify-chain used its own validation algorithm
which wasn't guaranteed to give the same result as the libgnutls
internal validation algorithm. Now this command print a new final
line with header 'Chain verification output:' that contains the result
from using the internal verification algorithm on the same chain.
** tests: Add crq_key_id self-test of gnutls_x509_crq_get_key_id.
** API and ABI modifications:
gnutls_x509_crq_get_key_id: ADDED.
* Version 2.7.3 (released 2008-12-10)
** libgnutls: Fix chain verification for chains that ends with RSA-MD2 CAs.

Andreas Metzler <ametzler@downhill.at.eu.org> in
<http://thread.gmane.org/gmane.comp.encryption.gpg.gnutls.devel/3309>.
** libgnutls: Libgcrypt initialization changed.
If libgcrypt has not already been initialized, GnuTLS will now
initialize libgcrypt with disabled secure memory. Initialize
libgcrypt explicitly in your application if you want to enable secure
memory. Before GnuTLS initialized libgcrypt to use GnuTLS's memory
allocation functions, which doesn't use secure memory, so there is no
real change in behaviour.
** libgnutls: Fix memory leak in PSK authentication.
Reported by Michael Weiser <michael@weiser.dinsnail.net> in
<http://permalink.gmane.org/gmane.network.gnutls.general/1465>.
** libgnutls: Small byte reads via gnutls_record_recv() optimized.
** certtool: Move gcry_control(GCRYCTL_ENABLE_QUICK_RANDOM, 0) call earlier.
It needs to be invoked before libgcrypt is initialized.
** gnutls-cli: Return non-zero exit code on error conditions.
** gnutls-cli: Corrected bug which caused a rehandshake request to be ignored.
** tests: Added chainverify self-test that tests X.509 chain verifications.
** API and ABI modifications:
No changes since last version.
* Version 2.7.2 (released 2008-11-18)
** libgnutls: Fix X.509 certificate chain validation error. [GNUTLS-SA-2008-3]
The flaw makes it possible for man in the middle attackers (i.e.,
active attackers) to assume any name and trick GNU TLS clients into
trusting that name. Thanks for report and analysis from Martin von

* Version 2.6.6 (released 2009-04-30)
libgnutls: Corrected double free on signature verification failure.
Reported by Miroslav Kratochvil. See the advisory
for more details. [GNUTLS-SA-2009-1] [CVE-2009-1415]
libgnutls: Fix DSA key generation.
Noticed when investigating the previous GNUTLS-SA-2009-1 problem. All
DSA keys generated using GnuTLS 2.6.x are corrupt. See the advisory
for more details. [GNUTLS-SA-2009-2] [CVE-2009-1416]
libgnutls: Check expiration/activation time on untrusted certificates.
Reported by Romain Francoise. Before the
library did not check activation/expiration times on certificates, and
was documented as not doing so. We have realized that many
applications that use libgnutls, including gnutls-cli, fail to perform
proper checks. Implementing similar logic in all applications leads
to code duplication. Hence, we decided to check whether the current
time (as reported by the time function) is within the
activation/expiration period of certificates when verifying untrusted
certificates.
This changes the semantics of gnutls_x509_crt_list_verify, which in
turn is used by gnutls_certificate_verify_peers and
gnutls_certificate_verify_peers2. We add two new
gnutls_certificate_status_t codes for reporting the new error
condition, GNUTLS_CERT_NOT_ACTIVATED and GNUTLS_CERT_EXPIRED. We also
add a new gnutls_certificate_verify_flags flag,
GNUTLS_VERIFY_DISABLE_TIME_CHECKS, that can be used to disable the new
behaviour.
API and ABI modifications:
gnutls_x509_crt_list_verify: CHANGED, checks activation/expiration times.
gnutls_certificate_verify_peers: Likewise.
gnutls_certificate_verify_peers2: Likewise.
GNUTLS_CERT_NOT_ACTIVATED: ADDED.
GNUTLS_CERT_EXPIRED: ADDED.
GNUTLS_VERIFY_DISABLE_TIME_CHECKS: ADDED.
* Version 2.6.5 (released 2009-04-11)
** libgnutls: Added %SSL3_RECORD_VERSION priority string that allows to
specify the client hello message record version. Used to overcome buggy
TLS servers. Report by Martin von Gagern.
** GnuTLS no longer uses the libtasn1-config script to find libtasn1.
Libtasn1 0.3.4 or later is required. This is to align with the
upcoming libtasn1 v2.0 release that doesn't have a libtasn1-script.
** API and ABI modifications:
No changes since last version.
* Version 2.6.4 (released 2009-02-06)
** libgnutls: Accept chains where intermediary certs are trusted.
Before GnuTLS needed to validate the entire chain back to a
self-signed certificate. GnuTLS will now stop looking when it has
found an intermediary trusted certificate. The new behaviour is
useful when chains, for example, contains a top-level CA, an
intermediary CA signed using RSA-MD5, and an end-entity certificate.
To avoid chain validation errors due to the RSA-MD5 cert, you can
explicitly add the intermediary RSA-MD5 cert to your trusted certs.
The signature on trusted certificates are not checked, so the chain
has a chance to validate correctly. Reported by "Douglas E. Engert"
<deengert@anl.gov> in
<http://thread.gmane.org/gmane.comp.encryption.gpg.gnutls.devel/3351>.
** libgnutls: result_size in gnutls_hex_encode now holds

Major changes compared to the v2.0 branch:
* SRP support aligned with newly published RFC 5054.
* OpenPGP support aligned with newly published RFC 5081.
* Support for DSA2 keys.
* Support for Camellia cipher.
* Support for Opaque PRF Input extension.
* PKCS#8 parser now handle DSA keys.
* Change from GPLv2 to GPLv3 for command-line tools, libgnutls-extra,
etc. Notice that liblzo2 2.02 is licensed under GPLv2 only. Earlier
versions, such as 2.01 which is included with GnuTLS, is available under
GPLv2 or later. If this incompatibility causes problems, we recommend
you to disable LZO using --without-lzo. LZO compression is not a
standard TLS compression algorithm, so the impact should be minimal.
* Functions for disabling record protocol padding.
Works around bugs on Nokia/Ericsson phones.
* New functions gnutls_priority_set() for setting cipher priorities easily.
Priorities like "COMPAT" also enables other work arounds, such as
disabling padding.
* Other minor improvements and bug fixes.
Minor changes compared to the latest v2.1.8 release candidate:
* Update internal copy of libtasn1 to version 1.2.
* Certtool --verify-chain now handle inputs larger than 64kb.
This fixes the self-test "rsa-md5-collision" under MinGW+Wine with
recent versions of libgcrypt. The problem was that Wine with the
libgcrypt RNG generates huge amounts of debugging output.
* Translation updates.
Added Dutch translation. Updated Polish and Swedish translation.
Backwards incompatible API/ABI changes in GnuTLS 2.2
====================================================
To adapt to changes in the TLS extension specifications for OpenPGP
and SRP, the GnuTLS API had to be modified. This means breaking the
API and ABI backwards compatibility. That is something we try to
avoid unless it is necessary. We decided to also remove the already
deprecated stub functions for X.509 to XML conversion and TLS
authorization (see below) when we had the opportunity.
Generally, most applications does not need to be modified. Just
re-compile them against the latest GnuTLS release, and it should work
fine.
Applications that use the OpenPGP or SRP features needs to be
modified. Below is a list of the modified APIs and discussion of what
the minimal things you need to modify in your application to make it
work with GnuTLS 2.2.
Note that GnuTLS 2.2 also introduces new APIs -- such as
gnutls_set_priority() that is superior to
gnutls_set_default_priority() -- that you may want to start using.
However, using those new APIs is not required to use GnuTLS 2.2 since
the old functions continue are still supported. This text only
discuss what you minimally have to modify.
XML related changes
-------------------
The function `gnutls_x509_crt_to_xml' has been removed. It has been
deprecated and only returned an error code since GnuTLS version
1.2.11. Nobody has complained, so users doesn't seem to miss the
functionality. We don't know of any other library to convert X.509
certificates into XML format, but we decided (long ago) that GnuTLS
isn't the right place for this kind of functionality. If you want
help to find some other library to use here, please explain and
discuss your use case on help-gnutls <at> gnu.org.
TLS Authorization related changes
---------------------------------
Everything related to TLS authorizations have been removed, they were
only stub functions that returned an error code:
GNUTLS_SUPPLEMENTAL_AUTHZ_DATA
gnutls_authz_data_format_type_t
gnutls_authz_recv_callback_func
gnutls_authz_send_callback_func
gnutls_authz_enable
gnutls_authz_send_x509_attr_cert
gnutls_authz_send_saml_assertion
gnutls_authz_send_x509_attr_cert_url
gnutls_authz_send_saml_assertion_url
SRP related changes
-------------------
The callback gnutls_srp_client_credentials_function has a new
prototype, and its semantic has changed. You need to rewrite the
callback, see the updated function documentation and SRP example code
(doc/examples/ex-client-srp.c and doc/examples/ex-serv-srp.c) for more
information.
The alert codes GNUTLS_A_MISSING_SRP_USERNAME and
GNUTLS_A_UNKNOWN_SRP_USERNAME are no longer used by the SRP
specification, instead the GNUTLS_A_UNKNOWN_PSK_IDENTITY alert is
used. There are #define's to map the old names to the new. You may
run into problems if you have a switch-case with cases for both SRP
alerts, since they are now mapped to the same value. The solution is
to drop the SRP alerts from such switch cases, as they are now
deprecated in favor of GNUTLS_A_UNKNOWN_PSK_IDENTITY.
OpenPGP related changes
-----------------------
The function `gnutls_certificate_set_openpgp_keyserver' have been
removed. There is no replacement functionality inside GnuTLS. If you
need keyserver functionality, consider using the GnuPG tools.
All functions, types, and error codes related to OpenPGP trustdb
format have been removed. The trustdb format is a non-standard
GnuPG-specific format, and we recommend you to use key rings instead.
The following have been removed:
gnutls_certificate_set_openpgp_trustdb
gnutls_openpgp_trustdb_init
gnutls_openpgp_trustdb_deinit
gnutls_openpgp_trustdb_import
gnutls_openpgp_key_verify_trustdb
gnutls_openpgp_trustdb_t
GNUTLS_E_OPENPGP_TRUSTDB_VERSION_UNSUPPORTED
The following functions has an added parameter of the (new) type
`gnutls_openpgp_crt_fmt_t'. The type specify the format of the data
(binary or base64). The functions are:
gnutls_certificate_set_openpgp_key_file
gnutls_certificate_set_openpgp_key_mem
gnutls_certificate_set_openpgp_keyring_mem
gnutls_certificate_set_openpgp_keyring_file
To improve terminology and align with the X.509 interface, some
functions have been renamed. Compatibility mappings exists. The old
and new names of the affected functions and types are:
Old name New name
gnutls_openpgp_key_t gnutls_openpgp_crt_t
gnutls_openpgp_key_fmt_t gnutls_openpgp_crt_fmt_t
gnutls_openpgp_key_status_t gnutls_openpgp_crt_status_t
GNUTLS_OPENPGP_KEY GNUTLS_OPENPGP_CERT
GNUTLS_OPENPGP_KEY_FINGERPRINT GNUTLS_OPENPGP_CERT_FINGERPRINT
gnutls_openpgp_key_init gnutls_openpgp_crt_init
gnutls_openpgp_key_deinit gnutls_openpgp_crt_deinit
gnutls_openpgp_key_import gnutls_openpgp_crt_import

gnutls_openpgp_key_check_hostname gnutls_openpgp_crt_check_hostname
gnutls_openpgp_send_key gnutls_openpgp_send_cert
* Version 2.0.0 (released 2007-09-04)
The following changes have been made since GnuTLS 1.6:
* Support for external RSA/DSA signing for TLS client authentication.
This allows you to secure the private key better, for example by using
privilege-separation techniques between the private key and the
network client/server.
* Support for signing X.509 certificates using RSA with SHA-256/384/512.
* Experimental support for TLS 1.2 (disabled by default). The TLS 1.2
specification is not finalized yet, but we implement a draft version
for testing.
* Support for X.509 Proxy Certificates (RFC 3820)
* Support for Supplemental handshakes messages (RFC 4680).
* Support for TLS authorization extension (draft-housley-tls-authz-extns-07).
* Support for the X.509 'otherName' Subject Altnerative Names (for XMPP).
* Guile bindings for GnuTLS have been added, thanks to Ludovic Courtes.
* Improve logic of gnutls_set_default_priority() which can now be more
recommended.
* New APIs to enumerate supported algorithms in the library.
* New APIs to access X.509 Certificate extension sequentially.
* New APIs to print X.509 Certificates and CRLs in human readable formats.
* New APIs to extract X.509 Distinguished Names from certificates.
* New APIs to handle pathLenConstraint in X.509 Basic Constraints.
* Certtool can export more than one certificate to PKCS#12.
* Several message translation improvements.
* Instructions and improvements to easily set up a HTTPS test server.
* Included copies updated to Libtasn1 1.1 and OpenCDK 0.6.4.
* Build improvements for Windows, Mac OS X, uClinux, etc.
* GnuTLS is now developed in GIT.
* Improved manual
* Many bugfixes and minor improvements.
* Version 2.0.4 (released 2007-11-16)
** Corrected bug in decompression of expanded compression data.
** API and ABI modifications:
No changes since last version.
* Version 2.0.3 (released 2007-11-10)
** This version backports several fixes from the 2.1.x branch.
** Fixed PKCS #3 parameter export.
** Added gnutls_record_disable_padding() to allow servers talking to
buggy clients that complain if the TLS 1.0 record protocol padding is
used.
** Introduced gnutls_session_enable_compatibility_mode() to allow enabling
all supported compatibility options (like disabling padding).
** Corrected bug which did not allow a server to run without supporting
certificates.
** API and ABI modifications:
gnutls_session_enable_compatibility_mode: ADDED
gnutls_record_disable_padding: ADDED
Add LICENSE, commented out; it contains both LGPL-2.1 and GPL2 code.
* Version 2.0.2 (released 2007-10-17)
** TLS authorization support removed.
This technique may be patented in the future, and it is not of crucial
importance for the Internet community. After deliberation we have
concluded that the best thing we can do in this situation is to
encourage society not to adopt this technique. We have decided to
lead the way with our own actions.
** certtool: Fixed data corruption when using --outder.
** Fix configure-time Guile detection.
** API and ABI modifications:
GNUTLS_SUPPLEMENTAL_USER_MAPPING_DATA: ADDED. To avoid that the
gnutls_supplemental_data_format_type_t enum type becomes empty.
* Version 2.0.1 (released 2007-09-20)
** New directory doc/credentials/ with test credentials.
This collects the test credentials from the web page and from src/.
The script gnutls-http-serv has also been moved to that directory.
** Update SRP extension type and cipher suite with official IANA values.
This breaks backwards compatibility with SRP in older versions of
GnuTLS, but this is intentional to speed up the adoption of the
official values. The old values we used were incorrect.
** Guile: Fix `x509-certificate-dn-oid'
** API and ABI modifications:
No changes since last version.
While an update to a .0 version is somehow risky, it finishes the
unfortunate state that the pkgsrc gnutls didn't work with the pkgsrc
opencdk, which I wouldn't like to go into the next stable branch.
Release candidates have worked for me, and there is some time left
before the Q3 branch, so I'm confident.
changes:
* Support for external RSA/DSA signing for TLS client authentication
-many X.509 enhancements
Support for Supplemental handshakes messages (RFC 4680)
* Support for TLS authorization extension (draft-housley-tls-authz-extns-07)
* Improve logic of gnutls_set_default_priority()
* New APIs to enumerate supported algorithms in the library
* Certtool can export more than one certificate to PKCS#12
* Several message translation improvements
* Improved manual
* Many bugfixes and minor improvements
* Version 1.6.3 (released 2007-05-26)
** New API functions to extract DER encoded X.509 Subject/Issuer DN.
Suggested by Nate Nielsen <nielsen-list@memberwebs.com>. Backported
from the 1.7.x branch, see
<http://lists.gnu.org/archive/html/help-gnutls/2007-05/msg00029.html>.
** Have PKCS8 parser return better error codes.
Reported by Nate Nielsen <nielsen-list@memberwebs.com>, see
<http://lists.gnupg.org/pipermail/gnutls-dev/2007-May/001653.html> and
<http://lists.gnupg.org/pipermail/gnutls-dev/2007-May/001654.html>.
** Fix mem leak for sessions with client authentication via certificates.
Reported by Andrew W. Nosenko <andrew.w.nosenko@gmail.com>, see
<http://lists.gnupg.org/pipermail/gnutls-dev/2007-April/001539.html>.
** Fix building of 'tlsia' self test.
Earlier some gcc are known to build tlsia linking to
$prefix/lib/libgnutls-extra.so rather than the libgnutls-extra.so in
the build directory, even though command line parameters look OK.
Changing order of some parameters fixes it.
** API and ABI modifications:
gnutls_x509_crt_get_raw_issuer_dn: ADD.
gnutls_x509_crt_get_raw_dn: ADD.
* Version 1.6.2 (released 2007-04-18)
** Fix X.509 signing with RSA-PKCS#1 to set a NULL parameters fields.
Before, we remove the parameters field, which resulted in a slightly
different DER encoding which in turn caused signature verification
failures of GnuTLS-generated RSA certificates in some other
implementations (e.g., GnuPG 2.x's gpgsm). Depending on which RFCs
you read, this may or may not be correct, but our new behaviour appear
to be consistent with other widely used implementations.
** Regenerate the PKIX ASN.1 syntax tree.
For some reason, after changing the ASN.1 type of ldap-UID in the last
release, the generated C file built from the ASN.1 schema was not
refreshed. This can cause problems when reading/writing UID
components inside X.500 Distinguished Names. Reported by devel
<dev001@pas-world.com>.
** Updated translations.
** API and ABI modifications:
No changes since last version.
* Version 1.6.1 (released 2006-12-28)
** Fix the list of trusted CAs that server's send to clients.
Before, the list contained issuer DN's instead of subject DN's of the
trusted CAs. Reported by Max Kellermann
** Fix gnutls_certificate_set_x509_crl to initialize the CRL before using it.
Reported by Max Kellermann
** Encode UID fields in DN's as DirectoryString.
Before GnuTLS encoded and parsed UID fields as IA5String. This was
incorrect, it should have used DirectoryString. Now it will use
DirectoryString for the UID field, but for backwards compatibility it
will also accept IA5String UID's. Reported by Max Kellermann
** Fix ./configure failure with non-GCC compilers.
This fixes the following error message:
configure: error: conditional "HAVE_LD_OUTPUT_DEF" was never defined.
Reported by "Michael C. Vergallen"
* Version 1.6.0 (released 2006-11-17)
** No changes since 1.5.5.
The major changes compared to the 1.4.x branch are:
*** A GnuTLS C++ library is part of the official distribution.
Currently there are no examples or documentation, but hopefully this
will change. See gnutlsxx.h for the API.
*** Windows is a supported platform.
There are, however, two know bugs. One is related to select() in
command line tools (not, nota bene, in the library), the other is a
problem with libgcrypt that causes delays. Help is needed to resolve
those issues, so we feel we can't delay the release because of this.
*** New APIs for custom push/pull function error reporting.
The new APIs are gnutls_transport_set_errno and
gnutls_transport_set_global_errno. See the release notes for version
1.5.4 for more information.
*** Self tests are run under valgrind, if available. See --disable-valgrind.
* Version 1.4.4 (released 2006-09-12)
** Relax the test that caught signatures that exploit the variant of
** Bleichenbacher's Crypto 06 rump session attack on our
** verification logic flaw.
In particular, we now permit the digestAlgorithm.parameters field to
be present but empty, whereas in 1.4.3 we actually checked that the
field was absent.
** Revert the removal of debug information for the GNUTLS-SA-2006-3 problem.
The messages are only printed in debug mode, which is not recommended
for normal use, and thus logging this situation cannot be abused as an
oracle in typical recommended situations.
** API and ABI modifications:
No changes since last version.
* Version 1.4.3 (released 2006-09-08)
** Fix PKCS#1 verification to avoid a variant of Bleichenbacher's
** Crypto 06 rump session attack.
In particular, we check that the digestAlgorithm.parameters field is
empty, to avoid that it can contain "garbage" that may be used to
alter the numeric properties of the signature. See
<http://www.imc.org/ietf-openpgp/mail-archive/msg14307.html> (which is
not exactly the same as the problem we fix here). Reported by Yutaka
OIWA <y.oiwa@aist.go.jp>.
See GNUTLS-SA-2006-4 on http://www.gnutls.org/security.html for more
up to date information.
** Fix PKCS#1 decryption to avoid Bleichenbacher's Crypto 98 attack.
See <http://www.bell-labs.com/user/bleichen/papers/pkcs.ps.gz>.
Reported by Werner Koch <wk@gnupg.org>.
See GNUTLS-SA-2006-3 on http://www.gnutls.org/security.html for more
up to date information.
** Fix crash in gnutls_x509_crt_sign2 if passed a NULL issuer_key.
** API and ABI modifications:
No changes since last version.
* Version 1.4.2 (released 2006-08-12)
** Fix a crash (strcmp() on a NULL value) in the certificate verification logic.
This can happen if you call gnutls_certificate_verify_peers2 and have
a certain mix of local CA certificates and the peer send special
certificates, that together trigger certain behaviour. It is not
known at this point whether the crash can be triggered without the
special local CA certificate, and thus turn this into a remote crash
of clients that verify server certificates when they talk to a server
with the special server certificate. See GNUTLS-SA-2006-2 on
http://www.gnu.org/software/gnutls/security.html for more up to date
information. Reported by satyakumar <satyam_kkd@hyd.hellosoft.com>.
** Change SRP and Cert-Type extensions to match IANA registry.
** OpenCDK updated to 0.5.9 to fix some problems with OpenPGP support.
** Make --without-included-libtasn1 work.
Reported by Daniel Black <dragonheart@gentoo.org>.
** API and ABI modifications:
No changes since last version.
* Version 1.4.1 (released 2006-06-14)
** Replaced inactive ifdefs to enable openpgp support in test programs.
** Fixed bug in OpenPGP authentication handshake.
** Fixed typographical in man pages.
** Build fixes of the manual.
** Added Swedish translation.
** API and ABI modifications:
No changes since last version.
* Version 1.4.0 (released 2006-05-15)
** Remove GnuTLS 0.8.x compatibility functions.
** The libgcrypt RNG is initialized in gnutls_global_init().
** TLS/IA API changes from Emile van Bergen.
A dummy credential structure is not needed now, if you wish to use the
low-level TLS/IA API, simply call gnutls_ia_enable to enable TLS/IA on
a session.
** The self-tests are now run under valgrind, if it is installed.
** Libtasn1 is updated to 0.3.4, and that version is now required.
** The command line tools now use getaddrinfo and support IPv6.
** API and ABI modifications:
_gnutls_x509_get_raw_crt_activation_time,
_gnutls_x509_get_raw_crt_expiration_time: Removed.
gnutls_ia_require_inner_phase: Removed, replaced by gnutls_ia_enable.
gnutls_ia_enable: Added.
- Error messages are now translated using GNU Gettext.
- The function gnutls_x509_crt_to_xml now return an internal error.
This means that the code to convert X.509 certificates to XML format
does not work any more. The reason is that the function called
libtasn1 internal functions. It seems unclean for libtasn1 to export
the APIs needed here. Instead it would be better to implement XML
support inside libtasn1 properly. If you need this functionality
strongly, please consider looking into implementing this suggested
approach instead. As a workaround, you may also modify lib/x509/xml.c
(change '#if 1' to '#if 0') and build using --with-included-libtasn1.
- Doc fixes to explain that gnutls_record_send can block.
- gnutls-cli can now recognize services and port numbers with the -p option.
** New API to access the TLS master secret.
When possible, you should use the TLS PRF functions instead.
** Improved handling when multiple libraries use GnuTLS at the same time.
Now gnutls_global_init() can be called multiple times, and
gnutls_global_deinit() will only deallocate the structure when it has
been called as many times as gnutls_global_init() was called.
** Added a self test of TLS resume functionality.
** Fix crash in TLS resume code, caused by TLS/IA changes.
** Add 'const' keywords in various places, from Frediano ZIGLIO.
** The code was indented again, including the external header files.
** API and ABI modifications:
New functions to retrieve the master secret value:
gnutls_session_get_master_secret
Add a 'const' keyword to existing API:
gnutls_x509_crq_get_challenge_password
* Version 1.3.2 (released 2005-12-15)
** GnuTLS now support TLS Inner application (TLS/IA).
This is per draft-funk-tls-inner-application-extension-01. This
functionality is added to libgnutls-extra, so it is licensed under the
GNU General Public License.
** New APIs to access the TLS Pseudo-Random-Function (PRF).
The PRF is used by some protocols building on TLS, such as EAP-PEAP
and EAP-TTLS. One function to access the raw PRF and one to access
the PRF seeded with the client/server random fields are provided.
Suggested by Jouni Malinen <jkmaline@cc.hut.fi>.
** New APIs to acceess the client and server random fields in a session.
These fields can be useful by protocols using TLS. Note that these
fields are typically used as input to the TLS PRF, and if this is your
intended use, you should use the TLS PRF API that use the
client/server random field directly. Suggested by Jouni Malinen
<jkmaline@cc.hut.fi>.
** Internal type cleanups.
The uint8, uint16, uint32 types have been replaced by uint8_t,
uint16_t, uint32_t. Gnulib is used to guarantee the presence of
correct types on platforms that lack them. The uint type have been
replaced by unsigned.
** API and ABI modifications:
New functions to invoke the TLS Pseudo-Random-Function (PRF):
gnutls_prf
gnutls_prf_raw
New functions to retrieve the session's client and server random values:
gnutls_session_get_server_random
gnutls_session_get_client_random
New function, to perform TLS/IA handshake:
gnutls_ia_handshake
New function to decide whether to do a TLS/IA handshake:
gnutls_ia_handshake_p
New functions to allocate a TLS/IA credential:
gnutls_ia_allocate_client_credentials
gnutls_ia_free_client_credentials
gnutls_ia_allocate_server_credentials
gnutls_ia_free_server_credentials
New functions to handle the AVP callback:
gnutls_ia_set_client_avp_function
gnutls_ia_set_client_avp_ptr
gnutls_ia_get_client_avp_ptr
gnutls_ia_set_server_avp_function
gnutls_ia_set_server_avp_ptr
gnutls_ia_get_server_avp_ptr
New functions, to toggle TLS/IA application phases:
gnutls_ia_require_inner_phase
New function to mix session keys with inner secret:
gnutls_ia_permute_inner_secret
Low-level API (used internally by gnutls_ia_handshake):
gnutls_ia_endphase_send
gnutls_ia_send
gnutls_ia_recv
New functions that can be used after successful TLS/IA negotiation:
gnutls_ia_generate_challenge
gnutls_ia_extract_inner_secret
Enum type with TLS/IA modes:
gnutls_ia_mode_t
Enum type with TLS/IA packet types:
gnutls_ia_apptype_t
Enum values for TLS/IA alerts:
GNUTLS_A_INNER_APPLICATION_FAILURE
GNUTLS_A_INNER_APPLICATION_VERIFICATION
New error codes, to signal when an application phase has finished:
GNUTLS_E_WARNING_IA_IPHF_RECEIVED
GNUTLS_E_WARNING_IA_FPHF_RECEIVED
New error code to signal TLS/IA verify failure:
GNUTLS_E_IA_VERIFY_FAILED
* Version 1.3.1 (released 2005-12-08)
** Support for DHE-PSK cipher suites has been added.
This method offers perfect forward secrecy.
** Fix gnutls-cli STARTTLS hang when SIGINT is sent too quickly, thanks to
Otto Maddox <ottomaddox@fastmail.fm> and Nozomu Ando <nand@mac.com>.
** Corrected a bug in certtool for 64 bit machines. Reported
by Max Kellermann <max@duempel.org>.
** New function to set a X.509 private key and certificate pairs, and/or
CRLs, from an PKCS#12 file, suggested by Emile van Bergen
<emile@e-advies.nl>.
The integrity of the PKCS#12 file is protected through a password
based MAC; public-key based signatures for integrity protection are
not supported. PKCS#12 bags may be encrypted using password derived
symmetric keys, public-key based encryption is not supported. The
PKCS#8 keys may be encrypted using passwords. The API use the same
password for all operations. We believe that any more flexibility
create too much complexity that would hurt overall security, but may
add more PKCS#12 related APIs if real-world experience indicate
otherwise.
** gnutls_x509_privkey_import_pkcs8 now accept unencrypted PEM PKCS#8 keys,
reported by Emile van Bergen <emile@e-advies.nl>.
This will enable "certtool -k -8" to parse those keys.
** Certtool now generate keys in unencrypted PKCS#8 format for empty passwords.
Use "certtool -p -8" and press press enter at the prompt. Earlier,
certtool would have encrypted the key using an empty password.
** Certtool now accept --password for --key-info and encrypted PKCS#8 keys.
Earlier it would have prompted the user for it, even if --password was
supplied.
** Added self test of PKCS#8 parsing.
Unencrypted and encrypted (pbeWithSHAAnd3-KeyTripleDES-CBC and
pbeWithSHAAnd40BitRC2-CBC) formats are tested. The test is in
tests/pkcs8.
** API and ABI modifications:
New function to set X.509 credentials from a PKCS#12 file:
gnutls_certificate_set_x509_simple_pkcs12_file
New gnutls_kx_algorithm_t enum type:
GNUTLS_KX_DHE_PSK
New API to return session data (better data types than
gnutls_session_get_data):
gnutls_session_get_data2
New API to set PSK Diffie-Hellman parameters:
gnutls_psk_set_server_dh_params
* Version 1.3.0 (2005-11-15)
** Support for TLS Pre-Shared Key (TLS-PSK) ciphersuites have been added.
This add several new APIs, see below. Read the updated manual for
more information. A new self test "pskself" has been added, that will
test this functionality.
** The session resumption data are now system independent.
** The code has been re-indented to conform to the GNU coding style.
** Removed the RIPEMD ciphersuites.
** Added a discussion of the internals of gnutls in manual.
** Fixes for Tru64 UNIX 4.0D that lack MAP_FAILED, from Albert Chin.
** Remove trailing comma in enums, for IBM C v6, from Albert Chin.
** Make sure config.h is included first in a few files, from Albert Chin.
** Don't use C++ comments ("//") as they are invalid, from Albert Chin.
** Don't install SRP programs and man pages if --disable-srp-authentication,
from Albert Chin.
** API and ABI modifications:
New gnutls_kx_algorithm_t key exchange type: GNUTLS_KX_PSK
New gnutls_credentials_type_t credential type:
GNUTLS_CRD_PSK
New credential types:
gnutls_psk_server_credentials_t
gnutls_psk_client_credentials_t
New functions to allocate PSK credentials:
gnutls_psk_allocate_client_credentials
gnutls_psk_free_client_credentials
gnutls_psk_free_server_credentials
gnutls_psk_allocate_server_credentials
New enum type for PSK key flags:
gnutls_psk_key_flags
New function prototypes for credential callback:
gnutls_psk_client_credentials_function
gnutls_psk_server_credentials_function
New function to set PSK username and key:
gnutls_psk_set_client_credentials
New function to set PSK passwd file:
gnutls_psk_set_server_credentials_file
New function to extract PSK user in server:
gnutls_psk_server_get_username
New functions to set PSK callback:
gnutls_psk_set_server_credentials_function
gnutls_psk_set_client_credentials_function
Use size_t instead of int for output size parameter:
gnutls_srp_base64_encode
gnutls_srp_base64_decode
* Version 1.2.9 (2005-11-07)
- Documentation was updated and improved.
- RSA-MD2 is now supported for verifying digital signatures.
- Due to cryptographic advances, verifying untrusted X.509
certificates signed with RSA-MD2 or RSA-MD5 will now fail with a
GNUTLS_CERT_INSECURE_ALGORITHM verification output. For
applications that must remain interoperable, you can use the
GNUTLS_VERIFY_ALLOW_SIGN_RSA_MD2 or GNUTLS_VERIFY_ALLOW_SIGN_RSA_MD5
flags when verifying certificates. Naturally, this is not
recommended default behaviour for applications. To enable the
broken algorithms, call gnutls_certificate_set_verify_flags with the
proper flag, to change the verification mode used by
gnutls_certificate_verify_peers2.
- Make it possible to send empty data through gnutls_record_send,
to align with the send(2) API.
- Some changes in the certificate receiving part of handshake to prevent
some possible errors with non-blocking servers.
- Added numeric version symbols to permit simple CPP-based feature
tests, suggested by Daniel Stenberg <daniel@haxx.se>.
- The (experimental) low-level crypto alternative to libgcrypt used
earlier (Nettle) has been replaced with crypto code from gnulib.
This leads to easier re-use of these components in other projects,
leading to more review and simpler maintenance. The new configure
parameter --with-builtin-crypto replace the old --with-nettle, and
must be used if you wish to enable this functionality. See README
under "Experimental" for more information. Internally, GnuTLS has
been updated to use the new "Generic Crypto" API in gl/gc.h. The
API is similar to the old crypto/gc.h, because the gnulib code were
based on GnuTLS's gc.h.
- Fix compiler warning in the "anonself" self test.
- API and ABI modifications:
gnutls_x509_crt_list_verify: Added 'const' to prototype in <gnutls/x509.h>.
This doesn't reflect a change in behaviour,
so we don't break backwards compatibility.
GNUTLS_MAC_MD2: New gnutls_mac_algorithm_t value.
GNUTLS_DIG_MD2: New gnutls_digest_algorithm_t value.
GNUTLS_VERIFY_ALLOW_SIGN_RSA_MD2,
GNUTLS_VERIFY_ALLOW_SIGN_RSA_MD5: New gnutls_certificate_verify_flags values.
Use when calling
gnutls_x509_crt_list_verify,
gnutls_x509_crt_verify, or
gnutls_certificate_set_verify_flags.
GNUTLS_CERT_INSECURE_ALGORITHM: New gnutls_certificate_status_t value,
used when broken signature algorithms
is used (currently RSA-MD2/MD5).
LIBGNUTLS_VERSION_MAJOR,
LIBGNUTLS_VERSION_MINOR,
LIBGNUTLS_VERSION_PATCH,
LIBGNUTLS_VERSION_NUMBER: New CPP symbols, indicating the GnuTLS
version number, can be used for feature existence
tests.
* Version 1.2.8 (2005-10-07)
- Libgcrypt 1.2.2 is required to fix a bug for forking GnuTLS servers.
- Don't install the auxilliary libexamples library used by the
examples in doc/examples/ on "make install", report and tiny patch
from Thomas Klausner
- If you pass a X.509 CA or PGP trust database to the command line
tool, it will now abort the connection if the server certificate
validation fails. Use the parameter --insecure to continue even
after certificate validation failures. Inspired from discussion
with Alexander Kotelnikov
- The test for socklen_t has been moved to gnulib.
- Link failures for duplicate or missing "program_name" symbol has been fixed,
patch from Martin Lambers
- The command line tool and the examples no longer uses mmap or bzero,
to make them more portable, patch from Martin Lambers
- Made the PKCS #12 API handle null passwords. Based on patch by
Anton Altaparmakov
- The GTK-DOC manual should build with current released tools.
(But a copy of the output is included, so the tools are not required.)
- API and ABI modifications:
No changes since last version.
* Version 1.2.7 (2005-09-09)
- The GNUTLS and GNUTLS-EXTRA libraries are now built with versioned symbols.
- Certtool now complains when reading out-of-range X.509 serial
numbers, suggested by Fran
- Certtool now uses the readline library (when available) when reading
X.509 serial numbers.
- Fixed build problems in getpass on uClibc and Mingw32 platforms.
- Fixed compile warning regarding socklen_t on Mingw32, reported by
Martin Lambers
- Fixed examples in doc/examples/, suggested by Fran
- Gnulib is now used for the core library, enabling future code cleanups.
- The gnutls-cli tool now use gnutls_certificate_verify_peers2,
suggested by Daniel Stenberg
- Doc fixes for gnutls_transport_set_push and gnutls_transport_set_pull.
- Minilibtasn1 is now 0.2.17 (removed optional use of C99 macros).
- Disable zlib support if zlib.h is not present.
- A number of internal cleanups.
- API and ABI modifications:
No changes since last version.
pkgsrc change: do not install libexamples (looks like a bug)
- MiniLZO updated to version 2.01 and moved to separate directory.
- Collision between system LZO header files and MiniLZO header file fixed.
- Will now test for liblzo functionality in liblzo2 too.
- Minilibtasn1 is now 0.2.14 (no code changes).
- Some code changes to avoid GTK-DOC warnings.
- API and ABI modifications:
No changes since last version.
* Version 1.2.5 (2005-07-03)
- More builddir != srcdir fixes, reported by Mike Castle
- Fixed off-by-one bug in the size parameter of gnutls_x509_crt_get*_dn,
reported by Adam Langley
- Corrected some stuff in minilzo detection. Pointed out by
Sergey Lipnevich.
- MiniLZO updated to version 2.00.
- gnutls_x509_crt_list_import now accept a DER formatted CRL.
- API and ABI modifications:
No changes since last version.
