5Bugfix
6 * Fix memory leak in mbedtls_ssl_set_hostname() when called multiple times.
7 Found by projectgus and jethrogb, #836.
Simon Butcher5d39ace2017-10-02 19:12:54 +01008 * Fix usage help in ssl_server2 example. Found and fixed by Bei Lin.
Ron Eldorbac9d4d2017-10-03 15:58:26 +03009 * Parse signature algorithm extension when renegotiating. Previously,
10 renegotiated handshakes would only accept signatures using SHA-1
11 regardless of the peer's preferences, or fail if SHA-1 was disabled.
Andres Amaya Garciabc041132016-11-21 15:38:02 +000012 * Fix leap year calculation in x509_date_is_valid() to ensure that invalid
13 dates on leap years with 100 and 400 intervals are handled correctly. Found
14 by Nicholas Wilson. #694

Simon Butchera3050832017-08-10 10:48:33 +010019 * Fix authentication bypass in SSL/TLS: when authmode is set to optional,
Ron Eldorb5851192017-07-20 00:30:44 +020020 mbedtls_ssl_get_verify_result() would incorrectly return 0 when the peer's
21 X.509 certificate chain had more than MBEDTLS_X509_MAX_INTERMEDIATE_CA
Simon Butchera3050832017-08-10 10:48:33 +010022 (default: 8) intermediates, even when it was not trusted. This could be
23 triggered remotely from either side. (With authmode set to 'required'
24 (the default), the handshake was correctly aborted).
25 * Reliably zeroize sensitive data after use in AES example applications
Hanno Becker3948a102017-06-27 08:26:53 +010026 programs/aes/aescrypt2 and programs/aes/crypt_and_hash.
27 Found by Laurent Simon.
Ron Eldorb5851192017-07-20 00:30:44 +020028
29API Changes
30 * 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.
Simon Butchera3050832017-08-10 10:48:33 +010033 * With authmode set to optional, the TLS handshake is now aborted if the
Ron Eldorb5851192017-07-20 00:30:44 +020034 verification of the peer's certificate failed due to an overlong chain or
Simon Butchera3050832017-08-10 10:48:33 +010035 a fatal error in the verify callback.
Ron Eldorb5851192017-07-20 00:30:44 +020036
Ron Eldor5ff277e2017-07-20 00:30:44 +020037Bugfix
Simon Butchera3050832017-08-10 10:48:33 +010038 * Add a check if iv_len is zero in GCM, and return an error if it is zero.
39 Reported by roberto. #716
40 * Replace preprocessor condition from #if defined(MBEDTLS_THREADING_PTHREAD)
Ron Eldoree709f42017-01-09 19:27:59 +020041 to #if defined(MBEDTLS_THREADING_C) as the library cannot assume they will
42 always be implemented by pthread support. Fix for #696
Simon Butchera3050832017-08-10 10:48:33 +010043 * Fix a resource leak on Windows platforms in mbedtls_x509_crt_parse_path(),
44 in the case of an error. Found by redplait. #590
Ron Eldora886ce32017-01-12 14:50:50 +020045 * Add MBEDTLS_MPI_CHK to check for error value of mbedtls_mpi_fill_random.
46 Reported and fix suggested by guidovranken in #740
Andres AG0ff660e2017-02-10 14:39:58 +000047 * Fix a potential integer overflow in the version verification for DER
48 encoded X509 CRLs. The overflow would enable maliciously constructed CRLs
49 to bypass the version verification check. Found by Peng Li/Yueh-Hsun Lin,
50 KNOX Security, Samsung Research America
Andres AGb322be52017-02-17 13:54:43 +000051 * Fix a potential integer overflow in the version verification for DER
52 encoded X509 certificates. The overflow would enable maliciously
53 constructed certificates to bypass the certificate verification check.
54 * Fix potential integer overflow in the version verification for DER
55 encoded X509 CSRs. The overflow would enable maliciously constructed CSRs
56 to bypass the version verification check. Found by Peng Li/Yueh-Hsun Lin,
57 KNOX Security, Samsung Research America

Hanno Becker88647ac2017-06-09 11:30:33 +010067 * Fixed unlimited overread of heap-based buffer in mbedtls_ssl_read().
68 The issue could only happen client-side with renegotiation enabled.
69 Could result in DoS (application crash) or information leak
70 (if the application layer sent data read from mbedtls_ssl_read()
71 back to the server or to a third party). Can be triggered remotely.
Janos Follath4477bca2017-03-23 10:41:56 +000072 * Add exponent blinding to RSA private operations as a countermeasure
73 against side-channel attacks like the cache attack described in
74 https://arxiv.org/abs/1702.08719v2.
75 Found and fix proposed by Michael Schwarz, Samuel Weiser, Daniel Gruss,
76 Clémentine Maurice and Stefan Mangard.
Gilles Peskine8877ec22017-03-23 14:37:37 +010077 * Wipe stack buffers in RSA private key operations

79 Simon.
Gilles Peskine7344e1b2017-05-12 13:16:40 +020080 * Removed SHA-1 and RIPEMD-160 from the default hash algorithms for
81 certificate verification. SHA-1 can be turned back on with a compile-time
82 option if needed.
Gilles Peskine39e29812017-05-16 17:53:03 +020083 * Fixed offset in FALLBACK_SCSV parsing that caused TLS server to fail to
84 detect it sometimes. Reported by Hugo Leisink. #810
Manuel Pégourié-Gonnard230ee312017-05-11 12:49:51 +020085 * Tighten parsing of RSA PKCS#1 v1.5 signatures, to avoid a
86 potential Bleichenbacher/BERserk-style attack.
Janos Follath4477bca2017-03-23 10:41:56 +000087
Simon Butcher93d0f4b2017-05-13 23:00:05 +010088Bugfix

90 recent versions of the library. Found by Kyle Keen.
Janos Follath3fb1cc32017-06-16 14:04:08 +010091 * Fixed issue in the Threading module that prevented mutexes from
92 initialising. Found by sznaider. #667 #843
Hanno Beckeraa8a2bd2017-04-28 17:15:26 +010093 * Fix insufficient support for signature-hash-algorithm extension,
94 resulting in compatibility problems with Chrome. Found by hfloyrd. #823
Hanno Beckera3929ba2017-05-08 16:31:14 +010095 * Accept empty trusted CA chain in authentication mode
Janos Follath3fb1cc32017-06-16 14:04:08 +010096 MBEDTLS_SSL_VERIFY_OPTIONAL. Found by jethrogb. #864
97 * Fix implementation of mbedtls_ssl_parse_certificate() to not annihilate
Hanno Becker58897fb2017-07-27 15:10:21 +010098 fatal errors in authentication mode MBEDTLS_SSL_VERIFY_OPTIONAL and to
Janos Follath3fb1cc32017-06-16 14:04:08 +010099 reflect bad EC curves within verification result.
100 * Fix bug that caused the modular inversion function to accept the invalid
101 modulus 1 and therefore to hang. Found by blaufish. #641.
102 * Fix incorrect sign computation in modular exponentiation when the base is
103 a negative MPI. Previously the result was always negative. Found by Guido
104 Vranken.
105 * Fix a numerical underflow leading to stack overflow in mpi_read_file()
106 that was triggered uppon reading an empty line. Found by Guido Vranken.

Simon Butchere4b3df52017-02-26 02:01:22 +0000116 * Add checks to prevent signature forgeries for very large messages while
117 using RSA through the PK module in 64-bit systems. The issue was caused by
118 some data loss when casting a size_t to an unsigned int value in the
119 functions rsa_verify_wrap(), rsa_sign_wrap(), rsa_alt_sign_wrap() and
120 mbedtls_pk_sign(). Found by Jean-Philippe Aumasson.
Andres AG7cd7cf02016-12-08 17:08:44 +0000121 * Fixed potential livelock during the parsing of a CRL in PEM format in
122 mbedtls_x509_crl_parse(). A string containing a CRL followed by trailing
123 characters after the footer could result in the execution of an infinite
124 loop. The issue can be triggered remotely. Found by Greg Zaverucha,
125 Microsoft.
Janos Follath8dbb35a2017-01-27 16:05:20 +0000126 * Fixed a bug that caused freeing a buffer that was allocated on the stack,
127 when verifying the validity of a key on secp224k1. This could be
128 triggered remotely for example with a maliciously constructed certificate
Simon Butcher3ea1af22017-02-28 18:47:27 +0000129 and potentially could lead to remote code execution on some platforms.
Simon Butcherbd6882b2017-03-07 12:37:14 +0000130 Reported independently by rongsaws and Aleksandar Nikolic, Cisco Talos
131 team. #569 CVE-2017-2784

Andres AG8136e822016-12-09 17:26:23 +0000134 * Fix output certificate verification flags set by x509_crt_verify_top() when
135 traversing a chain of trusted CA. The issue would cause both flags,
136 MBEDTLS_X509_BADCERT_NOT_TRUSTED and MBEDTLS_X509_BADCERT_EXPIRED, to be
137 set when the verification conditions are not met regardless of the cause.
138 Found by Harm Verhagen and inestlerode. #665 #561
Simon Butcher0f862942017-02-02 13:08:37 +0000139 * Fix the redefinition of macro ssl_set_bio to an undefined symbol

143 that are reported when building mbed TLS with a config.h that does not
Simon Butcheref3d4e42017-02-02 16:36:59 +0000144 define MBEDTLS_PEM_PARSE_C. Found by omnium21. #562
Andres AG8efc7692016-12-15 17:01:16 +0000145 * Fix incorrect renegotiation condition in ssl_check_ctr_renegotiate() that
146 would compare 64 bits of the record counter instead of 48 bits as indicated
147 in RFC 6347 Section 4.3.1. This could cause the execution of the
148 renegotiation routines at unexpected times when the protocol is DTLS. Found
149 by wariua. #687
Andres AGc6559722016-10-24 11:23:36 +0100150 * Fixed multiple buffer overreads in mbedtls_pem_read_buffer() when parsing

160 cause buffer bound checks to be bypassed. Found by Eyal Itkin.
Janos Follath5ad40452017-02-03 12:36:59 +0000161 * Fixed heap overreads in mbedtls_x509_get_time(). Found by Peng
162 Li/Yueh-Hsun Lin, KNOX Security, Samsung Research America.
Andres AGf4cbe102016-12-08 17:19:21 +0000163 * Fix potential memory leak in mbedtls_x509_crl_parse(). The leak was caused
164 by missing calls to mbedtls_pem_free() in cases when a
Simon Butcher763e3272017-02-28 16:36:22 +0000165 MBEDTLS_ERR_PEM_NO_HEADER_FOOTER_PRESENT error was encountered. Found and
166 fix proposed by Guido Vranken. #722

Manuel Pégourié-Gonnardf4acfe12014-09-17 10:56:54 +0200459API Changes
Manuel Pégourié-Gonnarda25ffc32015-06-25 12:01:16 +0200460 * The library has been split into libmbedcrypto, libmbedx509, libmbedtls.
461 You now need to link to all of them if you use TLS for example.
Manuel Pégourié-Gonnardd54e6172015-04-28 17:56:12 +0200462 * All public identifiers moved to the mbedtls_* or MBEDTLS_* namespace.
Manuel Pégourié-Gonnard6e088f92015-05-06 17:53:08 +0100463 Some names have been further changed to make them more consistent.
Manuel Pégourié-Gonnardd54e6172015-04-28 17:56:12 +0200464 Migration helpers scripts/rename.pl and include/mbedlts/compat-1.3.h are
Manuel Pégourié-Gonnard6e088f92015-05-06 17:53:08 +0100465 provided. Full list of renamings in scripts/data_files/rename-1.3-2.0.txt
Manuel Pégourié-Gonnard898e0aa2015-06-18 15:28:12 +0200466 * Renamings of fields inside structures, not covered by the previous list:
Manuel Pégourié-Gonnard797f48a2015-06-18 15:45:05 +0200467 mbedtls_cipher_info_t.key_length -> key_bitlen
468 mbedtls_cipher_context_t.key_length -> key_bitlen
469 mbedtls_ecp_curve_info.size -> bit_size
Manuel Pégourié-Gonnardd54e6172015-04-28 17:56:12 +0200470 * Headers are now found in the 'mbedtls' directory (previously 'polarssl').
Manuel Pégourié-Gonnard6963ff02015-04-28 18:02:54 +0200471 * The following _init() functions that could return errors have
Manuel Pégourié-Gonnard2f84e972015-05-11 09:52:24 +0200472 been split into an _init() that returns void and another function that
Manuel Pégourié-Gonnard06939ce2015-05-11 11:25:46 +0200473 should generally be the first function called on this context after init:
Manuel Pégourié-Gonnard41d479e2015-04-29 00:48:22 +0200474 mbedtls_ssl_init() -> mbedtls_ssl_setup()
Manuel Pégourié-Gonnard6963ff02015-04-28 18:02:54 +0200475 mbedtls_ccm_init() -> mbedtls_ccm_setkey()

Manuel Pégourié-Gonnard2f84e972015-05-11 09:52:24 +0200477 mbedtls_hmac_drbg_init() -> mbedtls_hmac_drbg_seed(_buf)()
478 mbedtls_ctr_drbg_init() -> mbedtls_ctr_drbg_seed()
Tillmann Karras588ad502015-09-25 04:27:22 +0200479 Note that for mbedtls_ssl_setup(), you need to be done setting up the
Manuel Pégourié-Gonnard06939ce2015-05-11 11:25:46 +0200480 ssl_config structure before calling it.
Manuel Pégourié-Gonnard96936682015-06-02 15:14:15 +0100481 * Most ssl_set_xxx() functions (all except ssl_set_bio(), ssl_set_hostname(),
Manuel Pégourié-Gonnardcaace652015-05-11 09:57:11 +0200482 ssl_set_session() and ssl_set_client_transport_id(), plus
483 ssl_legacy_renegotiation()) have been renamed to mbedtls_ssl_conf_xxx()
484 (see rename.pl and compat-1.3.h above) and their first argument's type
485 changed from ssl_context to ssl_config.

Manuel Pégourié-Gonnard9a1a4d62015-05-11 10:35:53 +0200488 * The following functions have been introduced and must be used in callback
489 implementations (SNI, PSK) instead of their *conf counterparts:
490 mbedtls_ssl_set_hs_own_cert()
491 mbedtls_ssl_set_hs_ca_chain()
492 mbedtls_ssl_set_hs_psk()
Manuel Pégourié-Gonnardcaace652015-05-11 09:57:11 +0200493 * mbedtls_ssl_conf_ca_chain() lost its last argument (peer_cn), now set
Manuel Pégourié-Gonnardbc2b7712015-05-06 11:14:19 +0100494 using mbedtls_ssl_set_hostname().
Manuel Pégourié-Gonnard01e5e8c2015-05-11 10:11:56 +0200495 * mbedtls_ssl_conf_session_cache() changed prototype (only one context
Manuel Pégourié-Gonnard5cb33082015-05-06 18:06:26 +0100496 pointer, parameters reordered).
Manuel Pégourié-Gonnard866eb472015-05-25 19:41:37 +0200497 * On server, mbedtls_ssl_conf_session_tickets_cb() must now be used in
498 place of mbedtls_ssl_conf_session_tickets() to enable session tickets.
Manuel Pégourié-Gonnardfd474232015-06-23 16:34:24 +0200499 * The SSL debug callback gained two new arguments (file name, line number).
500 * Debug modes were removed.
Manuel Pégourié-Gonnard01e5e8c2015-05-11 10:11:56 +0200501 * mbedtls_ssl_conf_truncated_hmac() now returns void.
Manuel Pégourié-Gonnard96936682015-06-02 15:14:15 +0100502 * mbedtls_memory_buffer_alloc_init() now returns void.
Manuel Pégourié-Gonnarde6ef16f2015-05-11 19:54:43 +0200503 * X.509 verification flags are now an uint32_t. Affect the signature of:

505 mbedtls_x509_ctr_verify_info()
Manuel Pégourié-Gonnard96936682015-06-02 15:14:15 +0100506 mbedtls_x509_crt_verify() (flags, f_vrfy -> needs to be updated)
Manuel Pégourié-Gonnarde6ef16f2015-05-11 19:54:43 +0200507 mbedtls_ssl_conf_verify() (f_vrfy -> needs to be updated)
Manuel Pégourié-Gonnardbc6ff232015-06-02 16:33:08 +0100508 * The following functions changed prototype to avoid an in-out length
509 parameter:
510 mbedtls_base64_encode()
511 mbedtls_base64_decode()
512 mbedtls_mpi_write_string()
513 mbedtls_dhm_calc_secret()
Manuel Pégourié-Gonnard91895852015-06-30 13:34:45 +0200514 * In the NET module, all "int" and "int *" arguments for file descriptors
515 changed type to "mbedtls_net_context *".
Manuel Pégourié-Gonnard0b104b02015-05-14 21:52:40 +0200516 * net_accept() gained new arguments for the size of the client_ip buffer.

523 mbedtls_x509write_crt_set_key_usage() changed from int to unsigned.
Manuel Pégourié-Gonnarda958d692015-03-27 10:23:53 +0100524 * test_ca_list (from certs.h) is renamed to test_cas_pem and is only
525 available if POLARSSL_PEM_PARSE_C is defined (it never worked without).
526 * Test certificates in certs.c are no longer guaranteed to be nul-terminated
Manuel Pégourié-Gonnard75f90102015-03-27 09:56:18 +0100527 strings; use the new *_len variables instead of strlen().
Manuel Pégourié-Gonnard43b37cb2015-05-12 11:20:10 +0200528 * Functions mbedtls_x509_xxx_parse(), mbedtls_pk_parse_key(),
529 mbedtls_pk_parse_public_key() and mbedtls_dhm_parse_dhm() now expect the
530 length parameter to include the terminating null byte for PEM input.
Manuel Pégourié-Gonnard35f1d7f2015-03-19 12:42:40 +0000531 * Signature of mpi_mul_mpi() changed to make the last argument unsigned
Manuel Pégourié-Gonnard5b9e5b12015-05-26 17:46:09 +0200532 * calloc() is now used instead of malloc() everywhere. API of platform
533 layer and the memory_buffer_alloc module changed accordingly.
Manuel Pégourié-Gonnard1b8de572015-05-27 16:49:37 +0200534 (Thanks to Mansour Moufid for helping with the replacement.)
Manuel Pégourié-Gonnard88bdb0b2015-03-10 14:02:33 +0000535 * Change SSL_DISABLE_RENEGOTIATION config.h flag to SSL_RENEGOTIATION
536 (support for renegotiation now needs explicit enabling in config.h).
Manuel Pégourié-Gonnard60c793b2015-06-18 20:52:58 +0200537 * Split MBEDTLS_HAVE_TIME into MBEDTLS_HAVE_TIME and MBEDTLS_HAVE_TIME_DATE

Manuel Pégourié-Gonnard348bcb32015-03-31 14:01:33 +0200587 * Support for RSA_ALT contexts in the PK layer is now optional. Since is is
588 enabled in the default configuration, this is only noticeable if using a
589 custom config.h
Manuel Pégourié-Gonnard1028b742015-05-06 17:33:07 +0100590 * Default DHM parameters server-side upgraded from 1024 to 2048 bits.

610 mbedtls_ssl_conf_transport()
611 mbedtls_ssl_conf_max_version()
612 mbedtls_ssl_conf_min_version()
Manuel Pégourié-Gonnard0c890352015-05-13 10:28:41 +0200613 * DTLS no longer hard-depends on TIMING_C, but uses a callback interface
614 instead, see mbedtls_ssl_set_timer_cb(), with the Timing module providing
615 an example implementation, see mbedtls_timing_delay_context and
616 mbedtls_timing_set/get_delay().
