6 * Fix authentication bypass in SSL/TLS: when auth_mode is set to optional,
7 mbedtls_ssl_get_verify_result() would incorrectly return 0 when the peer's
8 X.509 certificate chain had more than MBEDTLS_X509_MAX_INTERMEDIATE_CA
9 (default: 8) intermediates, even when it was not trusted. Could be
10 triggered remotely on both sides. (With auth_mode set to required
11 (default), the handshake was correctly aborted.)
Simon Butcher9fae2222017-07-28 22:32:23 +010012 * Reliably zeroize sensitive data after use in AES example applications

Andres Amaya Garcia63e672b2017-07-07 13:19:13 +010016Features
17 * Add the functions mbedtls_platform_setup() and mbedtls_platform_teardown()
Andres Amaya Garcia052ac862017-07-12 11:27:05 +010018 and the context struct mbedtls_platform_context to perform
19 platform-specific setup and teardown operations. The macro
Andres Amaya Garcia586d3772017-07-18 10:24:26 +010020 MBEDTLS_PLATFORM_SETUP_TEARDOWN_ALT allows the functions to be overridden
21 by the user in a platform_alt.h file. This new APIs are required in some
Andres Amaya Garcia052ac862017-07-12 11:27:05 +010022 embedded environments that have hardware acceleration support.

Simon Butcher51e8c3e2017-07-20 12:33:41 +020024API Changes
25 * Reverted API/ABI breaking changes introduced in mbed TLS 2.5.1, to make the
26 API consistent with mbed TLS 2.5.0. Specifically removed the inline
27 qualifier from the functions mbedtls_aes_decrypt, mbedtls_aes_encrypt,
Simon Butcher256da0f2017-07-22 11:49:55 +020028 mbedtls_ssl_ciphersuite_uses_ec and mbedtls_ssl_ciphersuite_uses_psk. #978
29 Found by James Cowgill.
Simon Butcherb060cc22017-07-28 01:04:34 +010030 * Certificate verification functions now set flags to -1 in case the full
31 chain was not verified due to an internal error (including in the verify
32 callback) or chain length limitations.
33 * With authmode set to optional, handshake is now aborted if the
34 verification of the peer's certificate failed due to an overlong chain or
35 a fatal error in the vrfy callback.

Ron Eldor5a21fd62016-12-16 16:15:56 +020037Bugfix
38 * Add a check if iv_len is zero, and return an error if it is zero. reported
39 by roberto. #716
Ron Eldor8ab05952017-01-09 19:27:59 +020040 * Replace preproccessor condition from #if defined(MBEDTLS_THREADING_PTHREAD)
41 to #if defined(MBEDTLS_THREADING_C) as the library cannot assume they will
42 always be implemented by pthread support. Fix for #696
Ron Eldor3e19df52017-01-09 15:09:16 +020043 * Fix resource leak on windows platform, in mbedtls_x509_crt_parse_path.
44 In case of failure, when an error occures, goto cleanup.
45 Found by redplait #590
Ron Eldor7269fee2017-01-12 14:50:50 +020046 * Add MBEDTLS_MPI_CHK to check for error value of mbedtls_mpi_fill_random.
47 Reported and fix suggested by guidovranken in #740
Andres Amaya Garciaaa27dfe2017-05-04 11:05:55 +010048 * Fix conditional preprocessor directives in bignum.h to enable 64-bit
49 compilation when using ARM Compiler 6.
Simon Butcher00d3cc62017-07-26 17:25:55 +010050 * Fix a potential integer overflow in the version verification for DER
51 encoded X509 CRLs. The overflow would enable maliciously constructed CRLs
52 to bypass the version verification check. Found by Peng Li/Yueh-Hsun Lin,
53 KNOX Security, Samsung Research America
Andres AG2e3ddfa2017-02-17 13:54:43 +000054 * Fix potential integer overflow in the version verification for DER

Janos Follath32529402017-06-22 10:02:07 +010063 * Added config.h option MBEDTLS_NO_UDBL_DIVISION, to prevent the use of
Simon Butcher256da0f2017-07-22 11:49:55 +020064 64-bit division. #708
Janos Follathbfea4a72017-06-22 10:02:07 +010065 * Removed mutexes from ECP hardware accelerator code. Now all hardware
66 accelerator code in the library leaves concurrency handling to the
67 platform. Reported by Steven Cooreman. #863
Andres Amaya Garcia92fcfe22017-06-26 12:57:44 +010068 * Define the macro MBEDTLS_AES_ROM_TABLES in the configuration file
69 config-no-entropy.h to reduce the RAM footprint.

Hanno Beckerbf4c2e32017-06-09 11:28:45 +010074 * Fixed unlimited overread of heap-based buffer in mbedtls_ssl_read().
75 The issue could only happen client-side with renegotiation enabled.
76 Could result in DoS (application crash) or information leak
77 (if the application layer sent data read from mbedtls_ssl_read()
78 back to the server or to a third party). Can be triggered remotely.
Gilles Peskine5d2511c2017-05-12 13:16:40 +020079 * Removed SHA-1 and RIPEMD-160 from the default hash algorithms for
80 certificate verification. SHA-1 can be turned back on with a compile-time
81 option if needed.
Gilles Peskined50177f2017-05-16 17:53:03 +020082 * Fixed offset in FALLBACK_SCSV parsing that caused TLS server to fail to
83 detect it sometimes. Reported by Hugo Leisink. #810
Manuel Pégourié-Gonnardc1380de2017-05-11 12:49:51 +020084 * Tighten parsing of RSA PKCS#1 v1.5 signatures, to avoid a
85 potential Bleichenbacher/BERserk-style attack.

Hanno Beckereccf60c2017-06-05 15:19:01 +010087Bugfix
Janos Follath5a1c0e72017-06-16 09:00:07 +010088 * Remove size zero arrays from ECJPAKE test suite. Size zero arrays are not
89 valid C and they prevented the test from compiling in Visual Studio 2015
90 and with GCC using the -Wpedantic compilation option.
Hanno Becker7e5437a2017-04-28 17:15:26 +010091 * Fix insufficient support for signature-hash-algorithm extension,
92 resulting in compatibility problems with Chrome. Found by hfloyrd. #823
Janos Follath5a1c0e72017-06-16 09:00:07 +010093 * Fix behaviour that hid the original cause of fatal alerts in some cases
94 when sending the alert failed. The fix makes sure not to hide the error
Gilles Peskine3df98f52017-05-10 17:47:40 +020095 that triggered the alert.
Janos Follath5a1c0e72017-06-16 09:00:07 +010096 * Fix SSLv3 renegotiation behaviour and stop processing data received from
97 peer after sending a fatal alert to refuse a renegotiation attempt.
98 Previous behaviour was to keep processing data even after the alert has
99 been sent.
Hanno Becker39ae8cd2017-05-08 16:31:14 +0100100 * Accept empty trusted CA chain in authentication mode
101 MBEDTLS_SSL_VERIFY_OPTIONAL.
Janos Follath5a1c0e72017-06-16 09:00:07 +0100102 Found by jethrogb. #864
103 * Fix implementation of mbedtls_ssl_parse_certificate() to not annihilate
104 fatal errors in authentication mode MBEDTLS_SSL_VERIFY_OPTIONAL and to
105 reflect bad EC curves within verification result.
106 * Fix bug that caused the modular inversion function to accept the invalid
107 modulus 1 and therefore to hang. Found by blaufish. #641.
108 * Fix incorrect sign computation in modular exponentiation when the base is
109 a negative MPI. Previously the result was always negative. Found by Guido
110 Vranken.
111 * Fix a numerical underflow leading to stack overflow in mpi_read_file()
112 that was triggered uppon reading an empty line. Found by Guido Vranken.

Janos Follath5a1c0e72017-06-16 09:00:07 +0100115 * Send fatal alerts in more cases. The previous behaviour was to skip
116 sending the fatal alert and just drop the connection.
Janos Follath0a5154b2017-03-10 11:31:41 +0000117 * Clarify ECDSA documentation and improve the sample code to avoid
Janos Follath5a1c0e72017-06-16 09:00:07 +0100118 misunderstanding and potentially dangerous use of the API. Pointed out
Janos Follath0a5154b2017-03-10 11:31:41 +0000119 by Jean-Philippe Aumasson.

Gilles Peskine4a7f6a02017-03-23 14:37:37 +0100124 * Wipe stack buffers in RSA private key operations
Janos Follath5a1c0e72017-06-16 09:00:07 +0100125 (rsa_rsaes_pkcs1_v15_decrypt(), rsa_rsaes_oaep_decrypt). Found by Laurent
126 Simon.
Janos Follath45182a02017-03-23 10:41:56 +0000127 * Add exponent blinding to RSA private operations as a countermeasure
128 against side-channel attacks like the cache attack described in
129 https://arxiv.org/abs/1702.08719v2.
130 Found and fix proposed by Michael Schwarz, Samuel Weiser, Daniel Gruss,

Simon Butcher4775e832017-05-13 22:56:08 +0100133Features
Janos Follath5a1c0e72017-06-16 09:00:07 +0100134 * Add hardware acceleration support for the Elliptic Curve Point module.
135 This involved exposing parts of the internal interface to enable
136 replacing the core functions and adding and alternative, module level
137 replacement support for enabling the extension of the interface.
Janos Follath7a8a0902017-04-10 16:13:06 +0100138 * Add a new configuration option to 'mbedtls_ssl_config' to enable
139 suppressing the CA list in Certificate Request messages. The default
140 behaviour has not changed, namely every configured CAs name is included.
141
Andres AGf5bf7182017-03-03 14:09:56 +0000142API Changes
143 * The following functions in the AES module have been deprecated and replaced
144 by the functions shown below. The new functions change the return type from
145 void to int to allow returning error codes when using MBEDTLS_AES_ALT,
146 MBEDTLS_AES_DECRYPT_ALT or MBEDTLS_AES_ENCRYPT_ALT.
147 mbedtls_aes_decrypt() -> mbedtls_internal_aes_decrypt()
148 mbedtls_aes_encrypt() -> mbedtls_internal_aes_encrypt()
149
Andres Amaya Garcia75fdf632017-05-02 16:01:20 +0100150Bugfix
151 * Remove macros from compat-1.3.h that correspond to deleted items from most
152 recent versions of the library. Found by Kyle Keen.
Janos Follath5a1c0e72017-06-16 09:00:07 +0100153 * Fixed issue in the Threading module that prevented mutexes from
154 initialising. Found by sznaider. #667 #843
155 * Add checks in the PK module for the RSA functions on 64-bit systems.
156 The PK and RSA modules use different types for passing hash length and
157 without these checks the type cast could lead to data loss. Found by Guido
158 Vranken.
Hanno Becker61937d42017-04-26 15:01:23 +0100159 * Avoid shadowing of time and index functions through mbed TLS function
160 arguments. Found by inestlerode. Fixes #557.

Simon Butcherb65c2be2017-03-10 18:50:44 +0000165 * Add checks to prevent signature forgeries for very large messages while
166 using RSA through the PK module in 64-bit systems. The issue was caused by
167 some data loss when casting a size_t to an unsigned int value in the
168 functions rsa_verify_wrap(), rsa_sign_wrap(), rsa_alt_sign_wrap() and
169 mbedtls_pk_sign(). Found by Jean-Philippe Aumasson.
Andres AG939954c2016-12-08 17:08:44 +0000170 * Fixed potential livelock during the parsing of a CRL in PEM format in
171 mbedtls_x509_crl_parse(). A string containing a CRL followed by trailing
172 characters after the footer could result in the execution of an infinite
173 loop. The issue can be triggered remotely. Found by Greg Zaverucha,
174 Microsoft.
Janos Follath182013f2016-10-25 10:50:22 +0100175 * Removed MD5 from the allowed hash algorithms for CertificateRequest and
176 CertificateVerify messages, to prevent SLOTH attacks against TLS 1.2.
Simon Butcher0621b1f2017-02-05 16:48:47 +0000177 Introduced by interoperability fix for #513.
Janos Follath7dadc2f2017-01-27 16:05:20 +0000178 * Fixed a bug that caused freeing a buffer that was allocated on the stack,
179 when verifying the validity of a key on secp224k1. This could be
180 triggered remotely for example with a maliciously constructed certificate
Simon Butcher71e9d582017-02-28 18:47:27 +0000181 and potentially could lead to remote code execution on some platforms.

Andres AGd1650662016-12-09 17:26:23 +0000186 * Fix output certificate verification flags set by x509_crt_verify_top() when
187 traversing a chain of trusted CA. The issue would cause both flags,
188 MBEDTLS_X509_BADCERT_NOT_TRUSTED and MBEDTLS_X509_BADCERT_EXPIRED, to be
189 set when the verification conditions are not met regardless of the cause.
190 Found by Harm Verhagen and inestlerode. #665 #561
Simon Butcherd57c8f02017-02-02 13:08:37 +0000191 * Fix the redefinition of macro ssl_set_bio to an undefined symbol
192 mbedtls_ssl_set_bio_timeout in compat-1.3.h, by removing it.
193 Found by omlib-lin. #673
Andres AGc0db5112016-12-07 15:05:53 +0000194 * Fix unused variable/function compilation warnings in pem.c, x509_crt.c and
195 x509_csr.c that are reported when building mbed TLS with a config.h that
Simon Butchera333b3c2017-02-02 16:17:37 +0000196 does not define MBEDTLS_PEM_PARSE_C. Found by omnium21. #562
Andres AG2196c7f2016-12-15 17:01:16 +0000197 * Fix incorrect renegotiation condition in ssl_check_ctr_renegotiate() that
198 would compare 64 bits of the record counter instead of 48 bits as indicated
199 in RFC 6347 Section 4.3.1. This could cause the execution of the
200 renegotiation routines at unexpected times when the protocol is DTLS. Found
201 by wariua. #687
Andres AG703990b2016-10-24 11:23:36 +0100202 * Fixed multiple buffer overreads in mbedtls_pem_read_buffer() when parsing

Janos Follath87c98072017-02-03 12:36:59 +0000213 * Fixed heap overreads in mbedtls_x509_get_time(). Found by Peng
214 Li/Yueh-Hsun Lin, KNOX Security, Samsung Research America.
Andres AG5708dcb2016-12-08 17:19:21 +0000215 * Fix potential memory leak in mbedtls_x509_crl_parse(). The leak was caused
216 by missing calls to mbedtls_pem_free() in cases when a
Simon Butcherd02dc142017-02-28 16:36:22 +0000217 MBEDTLS_ERR_PEM_NO_HEADER_FOOTER_PRESENT error was encountered. Found and
218 fix proposed by Guido Vranken. #722
Simon Butcher956c58f2017-03-02 09:18:09 +0000219 * Fixed the templates used to generate project and solution files for Visual
220 Studio 2015 as well as the files themselves, to remove a build warning
221 generated in Visual Studio 2015. Reported by Steve Valliere. #742

223 Raised and fix suggested by Alan Gillingham in the mbed TLS forum. #771
Andres AGd1cc7f62017-01-06 13:17:35 +0000224 * Fix 1 byte buffer overflow in mbedtls_mpi_write_string() when the MPI
225 number to write in hexadecimal is negative and requires an odd number of
226 digits. Found and fixed by Guido Vranken.
Simon Butcher81cf88f2017-03-07 19:35:49 +0000227 * Fix unlisted DES configuration dependency in some pkparse test cases. Found
228 by inestlerode. #555
Andres AG6b171e42017-03-09 16:16:11 +0000229 * Fix a potential integer overflow in the version verification for DER

593 * The following _init() functions that could return errors have
Tillmann Karras588ad502015-09-25 04:27:22 +0200594 been split into an _init() that returns void and another function that
Manuel Pégourié-Gonnard06939ce2015-05-11 11:25:46 +0200595 should generally be the first function called on this context after init:
Manuel Pégourié-Gonnard96936682015-06-02 15:14:15 +0100596 mbedtls_ssl_init() -> mbedtls_ssl_setup()

Manuel Pégourié-Gonnard96936682015-06-02 15:14:15 +0100601 Note that for mbedtls_ssl_setup(), you need to be done setting up the
602 ssl_config structure before calling it.
Manuel Pégourié-Gonnard9a1a4d62015-05-11 10:35:53 +0200603 * Most ssl_set_xxx() functions (all except ssl_set_bio(), ssl_set_hostname(),
604 ssl_set_session() and ssl_set_client_transport_id(), plus
605 ssl_legacy_renegotiation()) have been renamed to mbedtls_ssl_conf_xxx()

Manuel Pégourié-Gonnard96936682015-06-02 15:14:15 +0100617 * mbedtls_ssl_conf_session_cache() changed prototype (only one context
Manuel Pégourié-Gonnarde6ef16f2015-05-11 19:54:43 +0200618 pointer, parameters reordered).
619 * On server, mbedtls_ssl_conf_session_tickets_cb() must now be used in
620 place of mbedtls_ssl_conf_session_tickets() to enable session tickets.
Manuel Pégourié-Gonnard96936682015-06-02 15:14:15 +0100621 * The SSL debug callback gained two new arguments (file name, line number).

638 * net_accept() gained new arguments for the size of the client_ip buffer.
Manuel Pégourié-Gonnarda958d692015-03-27 10:23:53 +0100639 * In the threading layer, mbedtls_mutex_init() and mbedtls_mutex_free() now
640 return void.
641 * ecdsa_write_signature() gained an addtional md_alg argument and
Manuel Pégourié-Gonnard75f90102015-03-27 09:56:18 +0100642 ecdsa_write_signature_det() was deprecated.
Manuel Pégourié-Gonnard43b37cb2015-05-12 11:20:10 +0200643 * pk_sign() no longer accepts md_alg == POLARSSL_MD_NONE with ECDSA.
644 * Last argument of x509_crt_check_key_usage() and
645 mbedtls_x509write_crt_set_key_usage() changed from int to unsigned.
Manuel Pégourié-Gonnard35f1d7f2015-03-19 12:42:40 +0000646 * test_ca_list (from certs.h) is renamed to test_cas_pem and is only
Manuel Pégourié-Gonnard5b9e5b12015-05-26 17:46:09 +0200647 available if POLARSSL_PEM_PARSE_C is defined (it never worked without).
648 * Test certificates in certs.c are no longer guaranteed to be nul-terminated
Manuel Pégourié-Gonnard1b8de572015-05-27 16:49:37 +0200649 strings; use the new *_len variables instead of strlen().
Manuel Pégourié-Gonnard88bdb0b2015-03-10 14:02:33 +0000650 * Functions mbedtls_x509_xxx_parse(), mbedtls_pk_parse_key(),
651 mbedtls_pk_parse_public_key() and mbedtls_dhm_parse_dhm() now expect the
Manuel Pégourié-Gonnard60c793b2015-06-18 20:52:58 +0200652 length parameter to include the terminating null byte for PEM input.
653 * Signature of mpi_mul_mpi() changed to make the last argument unsigned
Manuel Pégourié-Gonnardf4acfe12014-09-17 10:56:54 +0200654 * calloc() is now used instead of malloc() everywhere. API of platform
655 layer and the memory_buffer_alloc module changed accordingly.
Manuel Pégourié-Gonnardc0d74942015-06-23 12:30:57 +0200656 (Thanks to Mansour Moufid for helping with the replacement.)
Manuel Pégourié-Gonnardd54e6172015-04-28 17:56:12 +0200657 * Change SSL_DISABLE_RENEGOTIATION config.h flag to SSL_RENEGOTIATION
658 (support for renegotiation now needs explicit enabling in config.h).
659 * Split MBEDTLS_HAVE_TIME into MBEDTLS_HAVE_TIME and MBEDTLS_HAVE_TIME_DATE
Manuel Pégourié-Gonnardaff37e52015-05-11 18:11:57 +0200660 in config.h

Manuel Pégourié-Gonnard0a4fb092015-05-07 12:50:31 +0100735 * DTLS no longer hard-depends on TIMING_C, but uses a callback interface
736 instead, see mbedtls_ssl_set_timer_cb(), with the Timing module providing
737 an example implementation, see mbedtls_timing_delay_context and
Manuel Pégourié-Gonnard88d37852015-06-17 14:26:49 +0200738 mbedtls_timing_set/get_delay().
739 * With UDP sockets, it is no longer necessary to call net_bind() again
Manuel Pégourié-Gonnard0a4fb092015-05-07 12:50:31 +0100740 after a successful net_accept().

1915 POLARSSL_ERR_SSL_CONN_EOF on an EOF from its f_recv() function.
1916 ssl_read() returns 0 if a POLARSSL_ERR_SSL_CONN_EOF is received
1917 after the handshake.

2174 of gcc (bug reported by David Barrett)
2175 * Correctly handle the case in padlock_xcryptcbc() when input or
2176 ouput data is non-aligned by falling back to the software
2177 implementation, as VIA Nehemiah cannot handle non-aligned buffers

2194 peer may cause xyssl to loop indefinitely by sending a certificate
2195 for which the RSA signature check fails (bug reported by Benoit)
2196 * Added test vectors for: AES-CBC, AES-CFB, DES-CBC and 3DES-CBC,
2197 HMAC-MD5, HMAC-SHA1, HMAC-SHA-256, HMAC-SHA-384, and HMAC-SHA-512
