* Version 3.5.8 (released 2016-01-09)
** libgnutls: Ensure that multiple calls to the gnutls_set_priority_*
functions will not leave the verification profiles field to an
undefined state. The last call will take precedence.
** libgnutls: Ensure that GNUTLS_E_DECRYPTION_FAIL will be returned
by PKCS#8 decryption functions when an invalid key is provided. This
addresses regression on decrypting certain PKCS#8 keys.
** libgnutls: Introduced option to override the default priority string
used by the library. The intention is to allow support of system-wide
priority strings (as set with --with-system-priority-file). The
configure option is --with-default-priority-string.
** libgnutls: Require a valid IV size on all ciphers for PKCS#8 decryption.
This prevents crashes when decrypting malformed PKCS#8 keys.
** libgnutls: Fix crash on the loading of malformed private keys with certain
parameters set to zero.
** libgnutls: Fix double free in certificate information printing. If the PKIX
extension proxy was set with a policy language set but no policy specified,
that could lead to a double free.
** libgnutls: Addressed memory leaks in client and server side error paths
(issues found using oss-fuzz project)
** libgnutls: Addressed memory leaks in X.509 certificate printing error paths
(issues found using oss-fuzz project)
** libgnutls: Addressed memory leaks and an infinite loop in OpenPGP certificate
parsing. Fixes by Alex Gaynor. (issues found using oss-fuzz project)
** libgnutls: Addressed invalid memory accesses in OpenPGP certificate parsing.
(issues found using oss-fuzz project)
** API and ABI modifications:
No changes since last version.
* Version 3.5.7 (released 2016-12-8)
** libgnutls: Include CHACHA20-POLY1305 ciphersuites in the SECURE128
and SECURE256 priority strings.
** libgnutls: Require libtasn1 4.9; this ensures gnutls will correctly
operate with OIDs which have elements that exceed 2^32.
** libgnutls: The DN decoding functions output the traditional DN format
rather than the strict RFC4514 compliant textual DN. This reverts the
3.5.6 introduced change, and allows applications which depended on the
previous format to continue to function. Introduced new functions which
output the strict format by default, and can revert to the old one using
a flag.
** libgnutls: Improved TPM key handling. Check authorization requirements
prior to using a key and fix issue on loop for PIN input. Patches by
James Bottomley.
** libgnutls: In all functions accepting UTF-8 passwords, ensure that
passwords are normalized according to RFC7613. When invalid UTF-8
passwords are detected, they are only tolerated for decryption.
This introduces a libunistring dependency on GnuTLS. A version of
libunistring is included in the library for the platforms that do
not ship it; it can be used with the '--with-included-unistring'
option to configure script.
** libgnutls: When setting a subject alternative name in a certificate
which is in UTF-8 format, it will transparently be converted to IDNA form
prior to storing.
** libgnutls: GNUTLS_CRT_PRINT_ONELINE flag on gnutls_x509_crt_print()
will print the SHA256 key-ID instead of a certificate fingerprint.
** libgnutls: enhance the PKCS#7 verification capabilities. In the case
signers that are not discoverable using the trust list or input, use
the stored list as pool to generate a trusted chain to the signer.
** libgnutls: Improved MTU calculation precision for the CBC ciphersuites
under DTLS.
** libgnutls: [added missing news entry since 3.5.0]
No longer tolerate certificate key usage violations for
TLS signature verification, and decryption. That is GnuTLS will fail
to connect to servers which incorrectly use a restricted to signing certificate
for decryption, or vice-versa. This reverts the lax behavior introduced
in 3.1.0, due to several such broken servers being available. The %COMPAT
priority keyword can be used to work-around connecting on these servers.
** certtool: When exporting a CRQ in DER format ensure no text data are
intermixed. Patch by Dmitry Eremin-Solenikov.
** certtool: Include the SHA-256 variant of key ID in --certificate-info
options.
** p11tool: Introduced the --initialize-pin and --initialize-so-pin
options.
** API and ABI modifications:
gnutls_utf8_password_normalize: Added
gnutls_ocsp_resp_get_responder2: Added
gnutls_x509_crt_get_issuer_dn3: Added
gnutls_x509_crt_get_dn3: Added
gnutls_x509_rdn_get2: Added
gnutls_x509_dn_get_str2: Added
gnutls_x509_crl_get_issuer_dn3: Added
gnutls_x509_crq_get_dn3: Added
* Version 3.5.6 (released 2016-11-04)
** libgnutls: Enhanced the PKCS#7 parser to allow decoding old
(pre-rfc5652) structures with arbitrary encapsulated content.
** libgnutls: Introduced a function group to set known DH parameters
using groups from RFC7919.
** libgnutls: Added more strict RFC4514 textual DN encoding and decoding.
Now the generated textual DN is in reverse order according to RFC4514,
and functions which generate a DN from strings such gnutls_x509_crt_set_*dn()
set the expected DN (reverse of the provided string).
** libgnutls: Introduced time and constraints checks in the end certificate
in the gnutls_x509_crt_verify_data2() and gnutls_pkcs7_verify_direct()
functions.
** libgnutls: Set limits on the maximum number of alerts handled. That is,
applications using gnutls could be tricked into an busy loop if the
peer sends continuously alert messages. Applications which set a maximum
handshake time (via gnutls_handshake_set_timeout) will eventually recover
but others may remain in a busy loops indefinitely. This is related but
not identical to CVE-2016-8610, due to the difference in alert handling
of the libraries (gnutls delegates that handling to applications).
** libgnutls: Reverted the change which made the gnutls_certificate_set_*key*
functions return an index (introduced in 3.5.5), to avoid affecting programs
which explicitly check success of the function as equality to zero. In order
for these functions to return an index an explicit call to gnutls_certificate_set_flags
with the GNUTLS_CERTIFICATE_API_V2 flag is now required.
** libgnutls: Reverted the behavior of sending a status request extension even
without a response (introduced in 3.5.5). That is, we no longer reply to a
client's hello with a status request, with a status request extension. Although
that behavior is legal, it creates incompatibility issues with releases in
the gnutls 3.3.x branch.
** libgnutls: Delayed the initialization of the random generator at
the first call of gnutls_rnd(). This allows applications to load
on systems which getrandom() would block, without blocking until
real random data are needed.
** certtool: --get-dh-params will output parameters from the RFC7919
groups.
** p11tool: improvements in --initialize option.
** API and ABI modifications:
GNUTLS_CERTIFICATE_API_V2: Added
GNUTLS_NO_TICKETS: Added
gnutls_pkcs7_get_embedded_data_oid: Added
gnutls_anon_set_server_known_dh_params: Added
gnutls_certificate_set_known_dh_params: Added
gnutls_psk_set_server_known_dh_params: Added
gnutls_x509_crt_check_key_purpose: Added
* Version 3.5.5 (released 2016-10-09)
** libgnutls: enhanced gnutls_certificate_set_ocsp_status_request_file()
to allow importing multiple OCSP request files, one for each chain
provided.
** libgnutls: The gnutls_certificate_set_key* functions return an
index of the added chain. That index can be used either with
gnutls_certificate_set_ocsp_status_request_file(), or with
gnutls_certificate_get_crt_raw() and friends.
** libgnutls: Added SHA*, AES-GCM, AES-CCM and AES-CBC optimized implementations
for the aarch64 architecture. Uses Andy Polyakov's assembly code.
** libgnutls: Ensure proper cleanups on gnutls_certificate_set_*key()
failures due to key mismatch. This prevents leaks or double freeing
on such failures.
** libgnutls: Increased the maximum size of the handshake message hash.
This will allow the library to cope better with larger packets, as
the ones offered by current TLS 1.3 drafts.
** libgnutls: Allow to use client certificates despite them containing
disallowed algorithms for a session. That allows for example a client
to use DSA-SHA1 due to his old DSA certificate, without requiring him
to enable DSA-SHA1 (and thus make it acceptable for the server's certificate).
** libgnutls: Reverted AESNI code on x86 to earlier version as the
latest version was creating position depending code. Added checks
in the CI to detect position depending code early.
** guile: Update code to the I/O port API of Guile >= 2.1.4
This makes sure the GnuTLS bindings will work with the forthcoming 2.2
stable series of Guile, of which 2.1 is a preview.
** API and ABI modifications:
gnutls_certificate_set_ocsp_status_request_function2: Added
gnutls_session_ext_register: Added
gnutls_session_supplemental_register: Added
GNUTLS_E_PK_INVALID_PUBKEY: Added
GNUTLS_E_PK_INVALID_PRIVKEY: Added
hitch-1.4.4 (2016-12-22)
------------------------
- OpenSSL 1.1.0 compatibility fixes. OpenSSL 1.1.0 is now fully
supported with Hitch.
- Fix a bug in the OCSP refresh code that could make it loop with
immediate refreshes flooding an OCSP responder.
- Force the SSL_OP_SINGLE_DH_USE setting. This protects against an
OpenSSL vulnerability where a remote attacker could discover private
DH exponents (CVE-2016-0701).
hitch-1.4.3 (2016-11-14)
------------------------
- OCSP stapling is now enabled by default.
Users should create ocsp-dir (default: /var/lib/hitch/) and make it
writable for the hitch user.
- Build error due to man page generation on FreeBSD (most likely non-Linux)
has been fixed.
hitch-1.4.2 (2016-11-08)
------------------------
- Example configuration file hitch.conf.example has been shortened and
defaults moved into Hitch itself. Default cipher string is now what we
believe to be secure. Users are recommended to use the built-in default
from now on, unless they have special requirements.
- hitch.conf(5) manual has been added.
- Hitch will now send a TLS Close notification during connection teardown.
This fixes an incomplete read with a GnuTLS client when the backend
(thttpd) used EOF to signal end of data, leaving some octets discarded
by gnutls client-side. (Issue 127_)
- Autotools will now detect SO_REUSEPORT availability. (Issue 122_)
- Improved error handling on memory allocation failure.
configure test because the type in stddef.h is guarded by a c11 macro
(most likely).
Force the configure test to pass.
From David Shao in PR pkg/51793 (originally from FreeBSD ports).
1.79 2017-01-03
Patch to fix a few inline variable declarations that cause errors for
older compilers. From Andy Grundman. Thanks.
Patch: Generated C code is not compatible with MSVC, AIX cc,
probably others. Added some PREINIT blocks and replaced 2 cases of INIT with
PREINIT. From Andy Grundman. Thanks.
Patch to fix: Fails to compile if the OpenSSL library it's built
against has compression support compiled out. From Stephan
Wall. Thanks.
Added RSA_get_key_parameters() to return a list of pointers to RSA key
internals.
Patch to fix some documentation typos courtesy gregor herrmann.
RSA_get_key_parameters() is now only available prior OpenSSL 1.1.
Testing with openssl-1.1.0b.
Version 1.0.9
- Fix problem with compilation agains libressl
- Make tests use localy build c library instead of system one
Version 1.0.8
- Use p1_utils 1.0.6
- Make it possible to decode certificate to OTP format
- Make sure p1_sha isn't compiled to native code
SECURITY:
- default Policy Privilege Escalation: If a parent token did not have
the default policy attached to its token, it could still create
children with the default policy. This is no longer allowed (unless
the parent has sudo capability for the creation path). In most cases
this is low severity since the access grants in the default policy are
meant to be access grants that are acceptable for all tokens to have.
- Leases Not Expired When Limited Use Token Runs Out of Uses: When
using limited-use tokens to create leased secrets, if the
limited-use token was revoked due to running out of uses (rather than
due to TTL expiration or explicit revocation) it would fail to revoke
the leased secrets. These secrets would still be revoked when their
TTL expired, limiting the severity of this issue. An endpoint has been
added (auth/token/tidy) that can perform housekeeping tasks on the
token store; one of its tasks can detect this situation and revoke the
associated leases.
FEATURES:
- Policy UI (Enterprise): Vault Enterprise UI now supports viewing,
creating, and editing policies.
IMPROVEMENTS:
- http: Vault now sets a no-store cache control header to make it more
secure in setups that are not end-to-end encrypted
BUG FIXES:
- auth/ldap: Don't panic if dialing returns an error and starttls is
enabled; instead, return the error
- ui (Enterprise): Submitting an unseal key now properly resets the
form so a browser refresh isn't required to continue.
0.6.3 (December 6, 2016)
DEPRECATIONS/CHANGES:
- Request size limitation: A maximum request size of 32MB is imposed
to prevent a denial of service attack with arbitrarily large
requests
- LDAP denies passwordless binds by default: In new LDAP mounts, or
when existing LDAP mounts are rewritten, passwordless binds will be
denied by default. The new deny_null_bind parameter can be set to
false to allow these.
- Any audit backend activated satisfies conditions: Previously, when a
new Vault node was taking over service in an HA cluster, all audit
backends were required to be loaded successfully to take over active
duty. This behavior now matches the behavior of the audit logging
system itself: at least one audit backend must successfully be loaded.
The server log contains an error when this occurs. This helps keep a
Vault HA cluster working when there is a misconfiguration on a standby
node.
FEATURES:
- Web UI (Enterprise): Vault Enterprise now contains a built-in web UI
that offers access to a number of features, including
init/unsealing/sealing, authentication via userpass or LDAP, and K/V
reading/writing. The capability set of the UI will be expanding
rapidly in further releases. To enable it, set ui = true in the top
level of Vault's configuration file and point a web browser at your
Vault address.
- Google Cloud Storage Physical Backend: You can now use GCS for
storing Vault data
IMPROVEMENTS:
- auth/github: Policies can now be assigned to users as well as to
teams
- cli: Set the number of retries on 500 down to 0 by default (no
retrying). It can be very confusing to users when there is a pause
while the retries happen if they haven't explicitly set it. With
request forwarding the need for this is lessened anyways.
- core: Response wrapping is now allowed to be specified by backend
responses (requires backends gaining support)
- physical/consul: When announcing service, use the scheme of the
Vault server rather than the Consul client
- secret/consul: Added listing functionality to roles
- secret/postgresql: Added revocation_sql parameter on the role
endpoint to enable customization of user revocation SQL statements
- secret/transit: Add listing of keys
BUG FIXES:
- api/unwrap, command/unwrap: Increase compatibility of unwrap command
with Vault 0.6.1 and older
- api/unwrap, command/unwrap: Fix error when no client token exists
- auth/approle: Creating the index for the role_id properly
- auth/aws-ec2: Handle the case of multiple upgrade attempts when
setting the instance-profile ARN
- auth/ldap: Avoid leaking connections on login
- command/path-help: Use the actual error generated by Vault rather
than always using 500 when there is a path help error
- command/ssh: Use temporary file for identity and ensure its deletion
before the command returns
- cli: Fix error printing values with -field if the values contained
formatting directives
- command/server: Don't say mlock is supported on OSX when it isn't.
- core: Fix bug where a failure to come up as active node (e.g. if an
audit backend failed) could lead to deadlock
- physical/mysql: Fix potential crash during setup due to a query
failure
- secret/consul: Fix panic on user error
0.4.8 - 11/12/2014
- Added more acknowledgements and security considerations
0.4.7 - 11/12/2014
- Added TLS 1.2 support (Yngve Pettersen and Paul Sokolovsky)
- Don't offer SSLv3 by default (e.g. POODLE)
- Fixed bug with PyCrypto_RSA integration
- Fixed harmless bug that added non-prime into sieves list
- Added "make test" and "make test-dev" targets (Hubert Kario)
0.4.5 - 3/20/2013
- **API CHANGE**: TLSClosedConnectionError instead of ValueError when writing
to a closed connection. This inherits from socket.error, so should
interact better with SocketServer (see http://bugs.python.org/issue14574)
and other things expecting a socket.error in this situation.
- Added support for RC4-MD5 ciphersuite (if enabled in settings)
- This is allegedly necessary to connect to some Internet servers.
- Added TLSConnection.unread() function
- Switched to New-style classes (inherit from 'object')
- Minor cleanups
0.4.4 - 2/25/2013
- Added Python 3 support (Martin von Loewis)
- Added NPN client support (Marcelo Fernandez)
- Switched to RC4 as preferred cipher
- faster in Python, avoids "Lucky 13" timing attacks
- Fixed bug when specifying ciphers for anon ciphersuites
- Made RSA hashAndVerify() tolerant of sigs w/o encoded NULL AlgorithmParam
- (this function is not used for TLS currently, and this tolerance may
not even be necessary)
0.4.3 - 9/27/2012
- Minor bugfix (0.4.2 doesn't load tackpy)
0.4.2 - 9/25/2012
- Updated TACK (compatible with tackpy 0.9.9)
0.4.1 - 5/22/2012
- Fixed RSA padding bugs (w/help from John Randolph)
- Updated TACK (compatible with tackpy 0.9.7)
- Added SNI
- Added NPN server support (Sam Rushing/Google)
- Added AnonDH (Dimitris Moraitis)
- Added X509CertChain.parsePemList
- Improved XML-RPC (Kees Bos)
0.4.0 - 2/11/2012
- Fixed pycrypto support
- Fixed python 2.6 problems
0.3.9.x - 2/7/2012
Much code cleanup, in particular decomposing the handshake functions so they
are readable. The main new feature is support for TACK, an experimental
authentication method that provides a new way to pin server certificates (See
https://github.com/moxie0/Convergence/wiki/TACK ).
Also:
- Security Fixes
- Sends SCSV ciphersuite as per RFC 5746, to signal non-renegotiated
Client Hello. Does not support renegotiation (never has).
- Change from e=3 to e=65537 for generated RSA keys, not strictly
necessary but mitigates risk of sloppy verifier.
- 1/(n-1) countermeasure for BEAST.
- Behavior changes:
- Split cmdline into tls.py and tlstest.py, improved options.
- Formalized LICENSE.
- Defaults to closing socket after sending close_notify, fixes hanging.
problem that would occur sometime when waiting for other party's
close_notify.
- Update SRP to RFC 5054 compliance.
- Removed client handshake "callbacks", no longer support the SRP
re-handshake idiom within a single handshake function.
- Bugfixes
- Added hashlib support, removes Deprecation Warning due to sha and md5.
- Handled GeneratorExit exceptions that are a new Python feature, and
interfere with the async code if not handled.
- Removed:
- Shared keys (it was based on an ancient I-D, not TLS-PSK).
- cryptlib support, it wasn't used much, we have enough other options.
- cryptoIDs (TACK is better).
- win32prng extension module, as os.urandom is now available.
- Twisted integration (unused?, slowed down loading).
- Jython code (ancient, didn't work).
- Compat support for python versions < 2.7.
- Additions
- Support for TACK via TACKpy.
- Support for CertificateRequest.certificate_authorities ("reqCAs")
- Added TLSConnection.shutdown() to better mimic socket.
- Enabled Session resumption for XMLRPCTransport.
* Remove -ansi flag to be compatible with OCaml 4.04 (thanks Mark Shinwell, ).
* Use accessor functions for X509_STORE_CTX.
* Change CLIBS order to allow static linking.
For full changes, please refer ChangeLog file.
Future deprecation notice
=========================
We plan on retiring more legacy cryptography in future releases,
specifically:
* In approximately August 2017, removing remaining support for the
SSH v.1 protocol (client-only and currently compile-time disabled).
* In the same release, removing support for Blowfish and RC4 ciphers
and the RIPE-MD160 HMAC. (These are currently run-time disabled).
* Refusing all RSA keys smaller than 1024 bits (the current minimum
is 768 bits)
* The next release of OpenSSH will remove support for running sshd(8)
with privilege separation disabled.
* The next release of portable OpenSSH will remove support for
OpenSSL version prior to 1.0.1.
This list reflects our current intentions, but please check the final
release notes for future releases.
Potentially-incompatible changes
================================
This release includes a number of changes that may affect existing
configurations:
* This release removes server support for the SSH v.1 protocol.
* ssh(1): Remove 3des-cbc from the client's default proposal. 64-bit
block ciphers are not safe in 2016 and we don't want to wait until
attacks like SWEET32 are extended to SSH. As 3des-cbc was the
only mandatory cipher in the SSH RFCs, this may cause problems
connecting to older devices using the default configuration,
but it's highly likely that such devices already need explicit
configuration for key exchange and hostkey algorithms already
anyway.
* sshd(8): Remove support for pre-authentication compression.
Doing compression early in the protocol probably seemed reasonable
in the 1990s, but today it's clearly a bad idea in terms of both
cryptography (cf. multiple compression oracle attacks in TLS) and
attack surface. Pre-auth compression support has been disabled by
default for >10 years. Support remains in the client.
* ssh-agent will refuse to load PKCS#11 modules outside a whitelist
of trusted paths by default. The path whitelist may be specified
at run-time.
* sshd(8): When a forced-command appears in both a certificate and
an authorized keys/principals command= restriction, sshd will now
refuse to accept the certificate unless they are identical.
The previous (documented) behaviour of having the certificate
forced-command override the other could be a bit confusing and
error-prone.
* sshd(8): Remove the UseLogin configuration directive and support
for having /bin/login manage login sessions.
Changes since OpenSSH 7.3
=========================
This is primarily a bugfix release.
Security
--------
* ssh-agent(1): Will now refuse to load PKCS#11 modules from paths
outside a trusted whitelist (run-time configurable). Requests to
load modules could be passed via agent forwarding and an attacker
could attempt to load a hostile PKCS#11 module across the forwarded
agent channel: PKCS#11 modules are shared libraries, so this would
result in code execution on the system running the ssh-agent if the
attacker has control of the forwarded agent-socket (on the host
running the sshd server) and the ability to write to the filesystem
of the host running ssh-agent (usually the host running the ssh
client). Reported by Jann Horn of Project Zero.
* sshd(8): When privilege separation is disabled, forwarded Unix-
domain sockets would be created by sshd(8) with the privileges of
'root' instead of the authenticated user. This release refuses
Unix-domain socket forwarding when privilege separation is disabled
(Privilege separation has been enabled by default for 14 years).
Reported by Jann Horn of Project Zero.
* sshd(8): Avoid theoretical leak of host private key material to
privilege-separated child processes via realloc() when reading
keys. No such leak was observed in practice for normal-sized keys,
nor does a leak to the child processes directly expose key material
to unprivileged users. Reported by Jann Horn of Project Zero.
* sshd(8): The shared memory manager used by pre-authentication
compression support had a bounds checks that could be elided by
some optimising compilers. Additionally, this memory manager was
incorrectly accessible when pre-authentication compression was
disabled. This could potentially allow attacks against the
privileged monitor process from the sandboxed privilege-separation
process (a compromise of the latter would be required first).
This release removes support for pre-authentication compression
from sshd(8). Reported by Guido Vranken using the Stack unstable
optimisation identification tool (http://css.csail.mit.edu/stack/)
* sshd(8): Fix denial-of-service condition where an attacker who
sends multiple KEXINIT messages may consume up to 128MB per
connection. Reported by Shi Lei of Gear Team, Qihoo 360.
* sshd(8): Validate address ranges for AllowUser and DenyUsers
directives at configuration load time and refuse to accept invalid
ones. It was previously possible to specify invalid CIDR address
ranges (e.g. user@127.1.2.3/55) and these would always match,
possibly resulting in granting access where it was not intended.
