@@ -6,7 +6,143 @@ Features
* Add support for ARIA cipher (RFC 5794) and associated TLS ciphersuites
(RFC 6209). Disabled by default, see MBEDTLS_ARIA_C in config.h
= mbed TLS 2.7.x branch released 2018-xx-xx
API Changes
* Extend the platform module with a util component that contains
functionality shared by multiple Mbed TLS modules. At this stage
platform_util.h (and its associated platform_util.c) only contain
mbedtls_platform_zeroize(), which is a critical function from a security
point of view. mbedtls_platform_zeroize() needs to be regularly tested
against compilers to ensure that calls to it are not removed from the
output binary as part of redundant code elimination optimizations.
Therefore, mbedtls_platform_zeroize() is moved to the platform module to
facilitate testing and maintenance.
= mbed TLS 2.9.0 branch released 2018-04-30
Security
* Fix an issue in the X.509 module which could lead to a buffer overread
during certificate validation. Additionally, the issue could also lead to
unnecessary callback checks being made or to some validation checks to be
omitted. The overread could be triggered remotely, while the other issues
would require a non DER-compliant certificate to be correctly signed by a
trusted CA, or a trusted CA with a non DER-compliant certificate. Found by
luocm. Fixes #825.
* Fix the buffer length assertion in the ssl_parse_certificate_request()
function which led to an arbitrary overread of the message buffer. The
overreads could be caused by receiving a malformed message at the point
where an optional signature algorithms list is expected when the signature
algorithms section is too short. In builds with debug output, the overread
data is output with the debug data.
* Fix a client-side bug in the validation of the server's ciphersuite choice
which could potentially lead to the client accepting a ciphersuite it didn't
offer or a ciphersuite that cannot be used with the TLS or DTLS version
chosen by the server. This could lead to corruption of internal data
structures for some configurations.
Features
* Add an option, MBEDTLS_AES_FEWER_TABLES, to dynamically compute smaller AES
tables during runtime, thereby reducing the RAM/ROM footprint by ~6KiB.
Suggested and contributed by jkivilin in pull request #394.
* Add initial support for Curve448 (RFC 7748). Only mbedtls_ecp_mul() and
ECDH primitive functions (mbedtls_ecdh_gen_public(),
mbedtls_ecdh_compute_shared()) are supported for now. Contributed by
Nicholas Wilson in pull request #348.
API Changes
* Extend the public API with the function of mbedtls_net_poll() to allow user
applications to wait for a network context to become ready before reading
or writing.
* Add function mbedtls_ssl_check_pending() to the public API to allow
a check for whether more more data is pending to be processed in the
internal message buffers.
This function is necessary to determine when it is safe to idle on the
underlying transport in case event-driven IO is used.
Bugfix
* Fix a spurious uninitialized variable warning in cmac.c. Fix independently
contributed by Brian J Murray and David Brown.
* Add missing dependencies in test suites that led to build failures
in configurations that omit certain hashes or public-key algorithms.
Fixes #1040.
* Fix C89 incompatibility in benchmark.c. Contributed by Brendan Shanks.
#1353
* Add missing dependencies for MBEDTLS_HAVE_TIME_DATE and
MBEDTLS_VERSION_FEATURES in some test suites. Contributed by
Deomid Ryabkov. Fixes #1299, #1475.
* Fix the Makefile build process for building shared libraries on Mac OS X.
Fixed by mnacamura.
* Fix parsing of PKCS#8 encoded Elliptic Curve keys. Previously Mbed TLS was
unable to parse keys which had only the optional parameters field of the
ECPrivateKey structure. Found by Jethro Beekman, fixed in #1379.
* Return the plaintext data more quickly on unpadded CBC decryption, as
stated in the mbedtls_cipher_update() documentation. Contributed by
Andy Leiserson.
* Fix overriding and ignoring return values when parsing and writing to
a file in pk_sign program. Found by kevlut in #1142.
* Restrict usage of error code MBEDTLS_ERR_SSL_WANT_READ to situations
where data needs to be fetched from the underlying transport in order
to make progress. Previously, this error code was also occasionally
returned when unexpected messages were being discarded, ignoring that
further messages could potentially already be pending to be processed
in the internal buffers; these cases led to deadlocks when event-driven
I/O was used. Found and reported by Hubert Mis in #772.
* Fix buffer length assertions in the ssl_parse_certificate_request()
function which leads to a potential one byte overread of the message
buffer.
* Fix invalid buffer sizes passed to zlib during record compression and
decompression.
* Fix the soversion of libmbedcrypto to match the soversion of the
maintained 2.7 branch. The soversion was increased in Mbed TLS
version 2.7.1 to reflect breaking changes in that release, but the
increment was missed in 2.8.0 and later releases outside of the 2.7 branch.
Changes
* Remove some redundant code in bignum.c. Contributed by Alexey Skalozub.
* Support cmake builds where Mbed TLS is a subproject. Fix contributed
independently by Matthieu Volat and Arne Schwabe.
* Improve testing in configurations that omit certain hashes or
public-key algorithms. Includes contributions by Gert van Dijk.
* Improve negative testing of X.509 parsing.
* Do not define global mutexes around readdir() and gmtime() in
configurations where the feature is disabled. Found and fixed by Gergely
Budai.
* Harden the function mbedtls_ssl_config_free() against misuse, so that it
doesn't leak memory if the user doesn't use mbedtls_ssl_conf_psk() and
instead incorrectly manipulates the configuration structure directly.
Found and fix submitted by junyeonLEE in #1220.
* Provide an empty implementation of mbedtls_pkcs5_pbes2() when
MBEDTLS_ASN1_PARSE_C is not enabled. This allows the use of PBKDF2
without PBES2. Fixed by Marcos Del Sol Vives.
* Add the order of the base point as N in the mbedtls_ecp_group structure
for Curve25519 (other curves had it already). Contributed by Nicholas
Wilson #481
* Improve the documentation of mbedtls_net_accept(). Contributed by Ivan
Krylov.
* Improve the documentation of mbedtls_ssl_write(). Suggested by
Paul Sokolovsky in #1356.
* Add an option in the Makefile to support ar utilities where the operation
letter must not be prefixed by '-', such as LLVM. Found and fixed by
Alex Hixon.
* Allow configuring the shared library extension by setting the DLEXT
environment variable when using the project makefiles.
* Optimize unnecessary zeroing in mbedtls_mpi_copy. Based on a contribution
by Alexey Skalozub in #405.
* In the SSL module, when f_send, f_recv or f_recv_timeout report
transmitting more than the required length, return an error. Raised by
Sam O'Connor in #1245.
* Improve robustness of mbedtls_ssl_derive_keys against the use of
HMAC functions with non-HMAC ciphersuites. Independently contributed
by Jiayuan Chen in #1377. Fixes #1437.
* Improve security of RSA key generation by including criteria from
FIPS 186-4. Contributed by Jethro Beekman. #1380
* Declare functions in header files even when an alternative implementation
of the corresponding module is activated by defining the corresponding
MBEDTLS_XXX_ALT macro. This means that alternative implementations do
not need to copy the declarations, and ensures that they will have the
same API.
* Add platform setup and teardown calls in test suites.
