mbed TLS ChangeLog (Sorted per branch, date)
= mbed TLS 2.12.0 branch released 2018-07-25
Security
* Fix a vulnerability in TLS ciphersuites based on CBC and using SHA-384,
in (D)TLS 1.0 to 1.2, that allowed an active network attacker to
partially recover the plaintext of messages under some conditions by
exploiting timing measurements. With DTLS, the attacker could perform
this recovery by sending many messages in the same connection. With TLS
or if mbedtls_ssl_conf_dtls_badmac_limit() was used, the attack only
worked if the same secret (for example a HTTP Cookie) has been repeatedly
sent over connections manipulated by the attacker. Connections using GCM
or CCM instead of CBC, using hash sizes other than SHA-384, or using
Encrypt-then-Mac (RFC 7366) were not affected. The vulnerability was
caused by a miscalculation (for SHA-384) in a countermeasure to the
original Lucky 13 attack. Found by Kenny Paterson, Eyal Ronen and Adi
Shamir.
* Fix a vulnerability in TLS ciphersuites based on CBC, in (D)TLS 1.0 to
1.2, that allowed a local attacker, able to execute code on the local
machine as well as manipulate network packets, to partially recover the
plaintext of messages under some conditions by using a cache attack
targetting an internal MD/SHA buffer. With TLS or if
mbedtls_ssl_conf_dtls_badmac_limit() was used, the attack only worked if
the same secret (for example a HTTP Cookie) has been repeatedly sent over
connections manipulated by the attacker. Connections using GCM or CCM
instead of CBC or using Encrypt-then-Mac (RFC 7366) were not affected.
Found by Kenny Paterson, Eyal Ronen and Adi Shamir.
* Add a counter-measure against a vulnerability in TLS ciphersuites based
on CBC, in (D)TLS 1.0 to 1.2, that allowed a local attacker, able to
execute code on the local machine as well as manipulate network packets,
to partially recover the plaintext of messages under some conditions (see
previous entry) by using a cache attack targeting the SSL input record
buffer. Connections using GCM or CCM instead of CBC or using
Encrypt-then-Mac (RFC 7366) were not affected. Found by Kenny Paterson,
Eyal Ronen and Adi Shamir.
Features
* Add new crypto primitives from RFC 7539: stream cipher Chacha20, one-time
authenticator Poly1305 and AEAD construct Chacha20-Poly1305. Contributed
by Daniel King.
* Add support for CHACHA20-POLY1305 ciphersuites from RFC 7905.
* Add platform support for the Haiku OS. (https://www.haiku-os.org).
Contributed by Augustin Cavalier.
* Make the receive and transmit buffers independent sizes, for situations
where the outgoing buffer can be fixed at a smaller size than the incoming
buffer, which can save some RAM. If buffer lengths are kept equal, there
is no functional difference. Contributed by Angus Gratton, and also
independently contributed again by Paul Sokolovsky.
* Add support for key wrapping modes based on AES as defined by
NIST SP 800-38F algorithms KW and KWP and by RFC 3394 and RFC 5649.
Bugfix
* Fix the key_app_writer example which was writing a leading zero byte which
was creating an invalid ASN.1 tag. Found by Aryeh R. Fixes #1257.
* Fix compilation error on C++, because of a variable named new.
Found and fixed by Hirotaka Niisato in #1783.
* Fix "no symbols" warning issued by ranlib when building on Mac OS X. Fix
contributed by tabascoeye.
* Clarify documentation for mbedtls_ssl_write() to include 0 as a valid
return value. Found by @davidwu2000. #839
* Fix a memory leak in mbedtls_x509_csr_parse(), found by catenacyber,
Philippe Antoine. Fixes #1623.
* Remove unused headers included in x509.c. Found by Chris Hanson and fixed
by Brendan Shanks. Part of a fix for #992.
* Fix compilation error when MBEDTLS_ARC4_C is disabled and
MBEDTLS_CIPHER_NULL_CIPHER is enabled. Found by TrinityTonic in #1719.
* Added length checks to some TLS parsing functions. Found and fixed by
Philippe Antoine from Catena cyber. #1663.
* Fix the inline assembly for the MPI multiply helper function for i386 and
i386 with SSE2. Found by László Langó. Fixes #1550
* Fix namespacing in header files. Remove the `mbedtls` namespacing in
the `#include` in the header files. Resolves #857
* Fix compiler warning of 'use before initialisation' in
mbedtls_pk_parse_key(). Found by Martin Boye Petersen and fixed by Dawid
Drozd. #1098
* Fix decryption for zero length messages (which contain all padding) when a
CBC based ciphersuite is used together with Encrypt-then-MAC. Previously,
such a message was wrongly reported as an invalid record and therefore lead
to the connection being terminated. Seen most often with OpenSSL using
TLS 1.0. Reported by @kFYatek and by Conor Murphy on the forum. Fix
contributed by Espressif Systems. Fixes #1632
* Fix ssl_client2 example to send application data with 0-length content
when the request_size argument is set to 0 as stated in the documentation.
Fixes #1833.
* Correct the documentation for `mbedtls_ssl_get_session()`. This API has
deep copy of the session, and the peer certificate is not lost. Fixes #926.
* Fix build using -std=c99. Fixed by Nick Wilson.
Changes
* Fail when receiving a TLS alert message with an invalid length, or invalid
zero-length messages when using TLS 1.2. Contributed by Espressif Systems.
* Change the default behaviour of mbedtls_hkdf_extract() to return an error
when calling with a NULL salt and non-zero salt_len. Contributed by
Brian J Murray
* Change the shebang line in Perl scripts to look up perl in the PATH.
Contributed by fbrosson.
* Allow overriding the time on Windows via the platform-time abstraction.
Fixed by Nick Wilson.
* Use gmtime_r/gmtime_s for thread-safety. Fixed by Nick Wilson.
= mbed TLS 2.11.0 branch released 2018-06-18
Features
* Add additional block mode, OFB (Output Feedback), to the AES module and
cipher abstraction module.
* Implement the HMAC-based extract-and-expand key derivation function
(HKDF) per RFC 5869. Contributed by Thomas Fossati.
* Add support for the CCM* block cipher mode as defined in IEEE Std. 802.15.4.
* Add support for the XTS block cipher mode with AES (AES-XTS).
Contributed by Aorimn in pull request #414.
* In TLS servers, support offloading private key operations to an external
cryptoprocessor. Private key operations can be asynchronous to allow
non-blocking operation of the TLS server stack.
Bugfix
* Fix the cert_write example to handle certificates signed with elliptic
curves as well as RSA. Fixes #777 found by dbedev.
* Fix for redefinition of _WIN32_WINNT to avoid overriding a definition
used by user applications. Found and fixed by Fabio Alessandrelli.
* Fix compilation warnings with IAR toolchain, on 32 bit platform.
Reported by rahmanih in #683
* Fix braces in mbedtls_memory_buffer_alloc_status(). Found by sbranden, #552.
Changes
* Changed CMake defaults for IAR to treat all compiler warnings as errors.
* Changed the Clang parameters used in the CMake build files to work for
versions later than 3.6. Versions of Clang earlier than this may no longer
work. Fixes #1072
= mbed TLS 2.10.0 branch released 2018-06-06
Features
* Add support for ARIA cipher (RFC 5794) and associated TLS ciphersuites
(RFC 6209). Disabled by default, see MBEDTLS_ARIA_C in config.h
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.
Bugfix
* Fix an issue with MicroBlaze support in bn_mul.h which was causing the
build to fail. Found by zv-io. Fixes #1651.
Changes
* Support TLS testing in out-of-source builds using cmake. Fixes #1193.
* Fix redundant declaration of mbedtls_ssl_list_ciphersuites. Raised by
TrinityTonic. #1359.

The mbed TLS library in Zephyr is a downstream of an externally maintained
open source project. The original upstream code can be found at:
https://tls.mbed.org/download/start/mbedtls-2.9.0-apache.tgz
https://tls.mbed.org/download/start/mbedtls-2.12.0-apache.tgz
At version 2.9.0
One change was applied in the original code. In mbedTLS both files,
net_sockets.c and x509.c, were defining _POSIX_C_SOURCE and as Zephyr
build all files together this was raising and warning. In order to
fix this problem one define guard was added, as showed bellow:
#if defined(_POSIX_C_SOURCE)
#undef _POSIX_C_SOURCE
#define _POSIX_C_SOURCE 200112L
#endif

* \brief Callback type: start external signature operation.
*
* This callback is called during an SSL handshake to start

* is no longer valid after this function returns.
*
* This function may call mbedtls_ssl_set_async_operation_data()
* to store an operation context for later retrieval
* by the resume or cancel callback.
*
* \note For RSA signatures, this function must produce output
* that is consistent with PKCS#1 v1.5 in the same way as
* mbedtls_rsa_pkcs1_sign(). Before the private key operation,
* apply the padding steps described in RFC 8017, section 9.2
* "EMSA-PKCS1-v1_5" as follows.
* - If \p md_alg is #MBEDTLS_MD_NONE, apply the PKCS#1 v1.5
* encoding, treating \p hash as the DigestInfo to be
* padded. In other words, apply EMSA-PKCS1-v1_5 starting
* from step 3, with `T = hash` and `tLen = hash_len`.
* - If `md_alg != MBEDTLS_MD_NONE`, apply the PKCS#1 v1.5
* encoding, treating \p hash as the hash to be encoded and
* padded. In other words, apply EMSA-PKCS1-v1_5 starting
* from step 2, with `digestAlgorithm` obtained by calling
* mbedtls_oid_get_oid_by_md() on \p md_alg.
*
* \note For ECDSA signatures, the output format is the DER encoding
* `Ecdsa-Sig-Value` defined in
* [RFC 4492 section 5.4](https://tools.ietf.org/html/rfc4492#section-5.4).
*
* \param ssl The SSL connection instance. It should not be

* \param cert Certificate containing the public key.
* In simple cases, this is one of the pointers passed to

/*
* This implementation should never be optimized out by the compiler
*
* This implementation for mbedtls_platform_zeroize() was inspired from Colin
* Percival's blog article at:
*
* http://www.daemonology.net/blog/2014-09-04-how-to-zero-a-buffer.html
*
* It uses a volatile function pointer to the standard memset(). Because the
* pointer is volatile the compiler expects it to change at
* any time and will not optimize out the call that could potentially perform
* other operations on the input buffer instead of just setting it to 0.
* Nevertheless, as pointed out by davidtgoldblatt on Hacker News
* (refer to http://www.daemonology.net/blog/2014-09-05-erratum.html for
* details), optimizations of the following form are still possible:
*
* if( memset_func != memset )
* memset_func( buf, 0, len );
*
* Note that it is extremely difficult to guarantee that
* mbedtls_platform_zeroize() will not be optimized out by aggressive compilers
* in a portable way. For this reason, Mbed TLS also provides the configuration
* option MBEDTLS_PLATFORM_ZEROIZE_ALT, which allows users to configure
* mbedtls_platform_zeroize() to use a suitable implementation for their
* platform and needs.
